Best Testo products in the Hygrometers category
On this page you'll find a ranking of the best Testo products in this category. To give you a quick overview, we've already ranked the most important information about the products for you.
1. Testo Humidity sensor head 0636 9736 0
Moisture sensor head for attachment to the wireless handle. Combine the moisture sensor head with your Testo thermal imaging camera. No manual input of moisture values is required anymore. The moisture sensor head transmits the moisture values directly to the thermal imaging camera.

2. Testo Anemometer 0563 0003
The compact climate set includes four app-controlled measuring devices for the essential measurement tasks of HVAC technicians: the testo 405i thermo-anemometer, the testo 410i vane anemometer, the testo 605i thermo-hygrometer, and the testo 805i infrared thermometer. When combined with a smartphone or tablet, these devices can measure air and surface temperatures, humidity, air speeds, and volumetric flows in, at, and around air conditioning units and systems. Users can conveniently read their measurements via the testo Smart Probes app installed on their device. In the app, measurement parameters such as humidity or temperature can be swapped, deleted, or added with just one click. It is also quick to change the displayed measurement values. Additionally, the app offers application-specific menus for identifying mold risks and automatically calculating the volumetric flow at the outlet or in the duct by simply parameterizing the outlet or duct cross-section. Finally, the measurement data log can be sent directly via email as a PDF or Excel file. The handy testo Smart Case allows for easy transport of the measuring devices, ensuring they are always on hand when needed.

3. Testo term Mini indicators (+116... +138 °C)
They are ideally suited for temperature monitoring of products and processes where a specific temperature should not be exceeded, such as for moving or small objects or for long-term monitoring. The temperature mini-indicators are delivered in a booklet containing 10 pieces each. They can be easily peeled off the booklet like stickers and adhered to the object being measured. The coloring is irreversible: once the temperature has been exceeded, the mini-indicator does not revert to its original color, even if the temperature drops again. This allows for critical temperature exceedances to be read even after a longer period of time.

4. Testo Material moisture meter 616 M
For a quick and non-destructive examination of the moisture content of wood and building materials. The display shows the weight percentage in relation to the dry mass of the material. The testo 616 makes it easier for anyone who needs to monitor the drying processes of floors, walls, and surfaces. It comes with integrated material calibration curves for softwood, hardwood, particle board, anhydrite screed, cement screed, sand-lime brick, aerated concrete, concrete, hollow bricks, and solid bricks. Non-destructive moisture measurement is particularly advantageous for precious woods.

5. Testo Humidity meter (hygrometer) 635-2
Measuring device for measuring air humidity, material moisture content, and measuring the dew point in compressed air systems. Humidity profiles can be recorded and analyzed and displayed graphically as well as in tables. Wireless, meaning that measurement data can be transmitted via radio, the testo 635-2 can display up to 3 temperature or humidity sensors. Selectable user profiles, i.e., a function key and menu layout tailored to the application, enable intuitive operation. Material moisture can be displayed directly due to the special sensors. Characteristic curves for various materials can be stored in the ComSoft software and transferred to the measuring device. To analyze moisture on ceilings and walls, the testo 635 directly shows the dew point distance between room air and wall surface. For checking the dew point in compressed air systems, precision sensors down to -60°C tpd are available. The moisture sensor developed by Testo itself is proven worldwide and offers outstanding characteristics in terms of precision, long-term stability, temperature resistance, and robustness.

6. Testo Humidity meter
With the compact Testo 625 Thermo-Hygrometer, you can easily, quickly, and accurately measure air temperature and relative humidity to assess indoor air quality or ensure optimal conditions in storage rooms. The Testo Smart App supports you with useful features such as configuration, display (including in second-screen mode), and storage as well as documentation of measurement values directly within the app.
Technical specifications:
- Temperature measurement range: -20 to +60 °C

- Acoustic alarm for exceeding limit values
Included:
+ Carrying case
+ Calibration protocol
+ 3x 1.5 V batteries (AA - LR6)
The Testo Smart App with all features is available for free download for Android and iOS.

7. Testo Humidity measuring device (Hygromet
Set for measurements in storage, cooling, and work spaces, in ventilation ducts, as well as on refrigeration systems and heat pumps. Safely stored in the case, you will receive the testo 440 climate measuring device and the humidity-temperature probe with Bluetooth. This allows you to start your work immediately.

8. Testo 605-H1 Calibrated to: Werkss
The thermo-hygrometer with the bend is small, compact, and precise. The long-term stable sensor ensures accurate measurements even after years. By measuring temperature and humidity, the testo 605 also determines the dew point responsible for mold formation, ranging from -20 to +50 °Ctd.

9. Testo term Mini indicators (+199... +224 °C)
They are ideally suited for temperature monitoring of products and processes where a specific temperature should not be exceeded, such as for moving or small objects or for long-term monitoring. The temperature mini-indicators are delivered in a booklet containing 10 pieces each. They can be easily peeled off the booklet like stickers and adhered to the object being measured. The coloration is irreversible: once the temperature has been exceeded, the mini-indicator does not revert to its original color, even if the temperature drops again. This allows for the detection of critical temperature exceedances even after a long period.

10. Testo Sintered cap for sensors PTFE
The sintered cap for sensors made of PTFE from Testo is a specialized accessory designed for use with the moisture measuring device testo 645. This sintered cap is particularly suitable for applications in high humidity areas and provides a reliable solution for continuous measurements. With a diameter of 12 mm and a robust construction from PTFE, it ensures high resistance to aggressive media and is ideal for compressed air measurements. The sintered cap features water-repellent properties that allow for favorable behavior during condensation. Its design supports high flow rates, making it an effective choice for precise measurements in challenging environments.
