Product Description:
The testo 830-T1 IR thermometer with laser measurement spot marker and 10:1 optics is suitable for non-contact surface temperature measurements in trade and industry.

Overview of the advantages of the testo 830-T1 infrared thermometer
Non-contact measurement of the surface temperature is accurate and fast with the testo 830-T1 infrared thermometer (2 measurements a second). To summarise the IR thermometer offers the following advantages:

High resolution processor for utmost accuracy (resolution 0.1 °C)
10:1 optics for precise measurements even at medium distances
IR thermometer with 1 point laser measurement spot marker to target the measuring point
Two alarm limit values that can be defined as required
Visual and acoustic alarm if limit value exceeded
Min./max. value display and hold function (to record a measured value)
Convenient one-handed operation thanks to the ergonomic gun-style design
Clear, illuminated digital display

The speed of the testo 830-T1 IR thermometer is impressive: it can take two measurements a second. This means you can undertake bigger measuring tasks fast and efficiently.

The infrared thermometer emission level can be individually set. This allows you to adjust it precisely to the material of the surface being measured to achieve the best possible measurement results. For untreated surfaces with a low emission level, we recommend using an emission tape (optional) which makes the IR measurement significantly easier.

Vane probe (Ø 100 mm) with Bluetooth including temperature sensor:
Use the vane probe (Ø 100 mm) to conveniently determine air velocity, volume flow and air temperature at air/ceiling outlets
Measuring range: +0.3 to +35 m/s, -20 to +70 °C
Endlessly versatile: a universal handle can be connected to all probe heads – so you can take care of more applications using less equipment, and save space too
The Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in the case. It transmits the readings to the testo 440 air velocity and IAQ measuring instrument, from up to 20 m away
Practical button on the handle: to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time
For convenient measurements at ceiling outlets: if required, you can also fit the vane probe with the extendable telescope with 90° angle and, if necessary, the telescope extension (both can be ordered separately; in combination 2 m long)
-nOur recommendation for carrying out accurate measurements at plate outlets/ventilation grilles: use the vane probe with the testovent 417 funnel set (available to order separately). If you add in the volume flow straightener (please order separately), you can achieve an impressively high level of precision when carrying out measurements at swirl outlets with turbulent air flow
Intelligent calibration concept: the testo 440 air velocity and IAQ measuring instrument remains in continuous use, since only the 100 mm vane probe head is sent in for calibration

The testo 410-1 vane anemometer is impressive thanks to its practical pocket size and is ideal for fast check measurements. With a measuring range of 0.4 to 20 m/s, the anemometer can even be used for low flow speeds.
The anemometer has a permanently mounted vane with a diameter of 40 mm. You can therefore use it for the integral measurement of air velocity at ventilation grilles (air outlets).
The anemometer is practical for outdoor operation: as well as air velocity and air temperature, the testo 410-1 also calculates the Beaufort wind force and the wind chill temperature, which is the temperature perceived by a person due to wind-related cooling.

The vane anemometer with practical functions
The testo 410-1 includes a plug-on protective cap, as well as a wrist strap for secure measurement, and enables you to take advantage of the following functions:
Single-point averaging: provides information on the average air velocity, e.g. at air outlets
Hold function: is used to record the current values relating to air velocity and air temperature and compare them with each other
Max/min values: get the minimum or maximum values since the anemometer was last switched on or reset, at the touch of a button
Illuminated display: read off your readings even in dark environments
Selectable units: for air velocity and temperature: m/s, km/h, fpm, mph, kts, Beaufort, °C, °F and wind chill

Measurement of air velocity, volumetric flow and air temperature
For measurements in ventilation ducts and in rooms
Particularly precise in the range between 0 and 2 m/s
Telescope extendible to 300 mm

Use the testo 405 thermal anemometer to measure air velocity, volumetric flow and air temperature. It is suitable for carrying out quick check measurements in ventilation ducts and for measuring the air velocity in rooms, e.g. at draughty windows.

Product Description:
If, in your capacity as an HVAC engineer, you carry out fast check measurements in ventilation ducts or in rooms, then our testo 405 thermal anemometer is a must-have. The anemometer features a permanently mounted telescope and enables you to measure air flow, volumetric flow and air temperature. The measuring range for flow is between 0 to 10 m/s, volumetric flows are calculated up to 99,990 m3/h.

The extendible telescope (up to 300 mm) makes the thermal anemometer particularly suitable for flow measurements in ventilation ducts. The illuminated display can be swivelled into various positions, ensuring that the readings can be read off comfortably. The duct bracket (included in the delivery) offers key practical advantages. You can use this to optimally position the telescope in the ventilation duct and obtain precise measurement results.

Since the testo 405 thermal anemometer measures particularly accurately in the range between 0 and 2 m/s, you can also use it to measure the air velocity in rooms. Low air velocities, at draughty windows for example, are quickly located and accurately measured using the anemometer.

Integrated sensor protection: when you are not using the testo 405 thermal anemometer, the rotating protective cap protects the flow sensor from mechanical stress.

Measures relative humidity and air temperature
Calculates the dew point
Ideal for measurements in ventilation ducts and in rooms
Measuring values easy to read off thanks to a pivoting display

The testo 605-H1 thermohygrometer enables reliable measurement of humidity and air temperature and calculation of the dew point. It has a permanently mounted probe shaft which means it is excellent when it comes to carrying out check measurements in ventilation ducts.

Product Description:
If you are looking for a compact, user-friendly thermohygrometer, the testo 605-H1 is the ideal choice. It measures relative humidity and air temperature and also calculates the dew point in the -20 to +50 °C td range. The built-in Testo humidity sensor ensures reliable measurement results with long-term stability.

The thermohygrometer is suitable for check measurements in production, storage, office and server areas. The testo 605-H1 is particularly practical for measurements in ventilation ducts, because it has a permanently mounted probe shaft (length: 125 mm). The bracket which is also supplied enables you to position and fix the probe shaft in the desired location in the ventilation duct. This means you can carry out your measurements without having to hold the thermohygrometer while doing so.

The design of the testo 605-H1 temperature and humidity measuring instrument has been well thought through, right down to the details: the display can be pivoted into different positions, enabling the measuring values to be read off easily. When you are not using the testo 605-H1, the rotating protective cap at the end of the probe shaft protects the sensor from mechanical stress.

Long, pointed thermocouple probe: ideal for measurements in liquids, soft or powdery substances and in the air

The testo 905-T1 penetration thermometer enables reliable temperature measurements in liquids, soft or powdery substances and in the air. In doing so, it is the temperature measuring instrument's large measuring range and its short response time that make it stand out. Both advantages are due to the high-quality type K thermocouple probe.

Product Description:
The testo 905-T1 penetration thermometer has a large measuring range from -50 to +350 °C and can even measure up to +500 °C for a short time (1 to 2 minutes). Its permanently integrated type K thermocouple probe makes this possible. In addition, the penetration thermometer is characterized by its short response time. The thermocouple probe reacts very quickly, particularly in water (or other liquids). The penetration thermometer is therefore ideally suited for measurements in fluid substances in laboratory, chemical and pharmaceutical areas.
However, as well as immersion/penetration of the long, pointed probe shaft in liquids and soft or powdery substances being possible, you can also insert it in ventilation ducts to measure the temperature there. The penetration thermometer is also a winner when it comes to accuracy, because it achieves a higher level than typical comparable models.

A really user-friendly penetration thermometer
The testo 905-T1 penetration thermometer is easy to use and very user-friendly. The measuring values are shown very legibly on the display. The fact that the display can be pivoted also makes reading easier. This is particularly practical, since the measuring values can be read off perfectly from many different perspectives.
