- The Testo 435-3 is a powerful and versatile instrument. It helps them to check and maintain the performance of their systems accurately and efficiently.
Probe of the Testo 435-3 multifunction meter
- Temperature probe :
- Air temperature probe : To measure air temperature in different environments.
- Surface temperature probe : Measures the temperature of surfaces by direct contact with them.
- Liquid temperature probe : For measuring the temperature of liquids.
- Humidity probe :
- Air Humidity Probe : Measures the relative humidity of the air. Helps control environmental conditions and maintain comfort.
- Wind speed probe :
- Anemometer : Measures wind speed and air flow. Important in performance testing and air conditioning.
- Pressure probe :
- Air Pressure Transducer : Measures pressure in air systems. Helps in testing and maintaining HVAC equipment.
- CO2 probe :
- CO2 Probe : Measures CO2 concentration in air. Ensures air quality in closed or crowded environments.
- Light probe :
- Light probe : Measures light intensity in lighting applications and work environments.
Testo 435-3 multifunction meter applications
-
Complex technology, but easy to handle
The testo 435-3 multifunction measuring instrument features efficient measuring features that make any inconvenient programming of the measuring instrument unnecessary:
Probe-dependent menus and selectable user profiles for the typical applications of “duct measurement” and “IAQ measurement” ensure the easiest handling imaginable.
All readings are easy to read on the large display with backlighting. In addition, the dew point distance, min., max. and average values are displayed. A robust housing provides reliable protection against impacts for the Testo 435-3 multi-function climate measuring instrument.
Documentation of measurement data on the website
The Testo fast printer, available as an option, means you can print out measurement data reports directly on site. For a duct measurement, you can print out current values or min./max. values for air velocity, volume flow, temperature and air humidity. You can use the printout as proof of your work.
Use the practical cyclic printing feature on the Testo 435-3. It allows not only the possibility of printing individual readings, but also of entire measurements on the Testo fast printer at freely adjustable intervals (e.g. once a minute).
We recommend the Testo 435-4 version for storing measurement data. It is equipped with a reading memory and PC software.
Technical specifications of the testo 435-3 multifunction meter
The Testo 435 multi-function climate measuring instrument is available in four versions. This Testo 435-3 version has an integrated differential pressure sensor with a measuring range of 0 hPa 25…. Differential pressure measurement allows you to check filters in ventilation and air conditioning systems or to measure air velocity using a Pitot tube (optional).
