435-1, multi-functional meas. instr., for A/C, ventilation and Indoor Air Quality, with battery and calibration protocol

The measuring instrument for ambient air conditions, for assessing Indoor Air Quality and adjusting and inspecting VAC systems. Model 435-1 is an affordable introduction to measurement engineering for ambient air conditions. The new IAQ probe measures Indoor Air Quality by measuring CO2 level, air moisture and air temperature. Temperature and humidity measurement is integrated in the new thermal probe. In addition, it is also possible to connect additional temperature probes. Readings from up to 3 temperature probes can be displayed in the clearly laid-out measuring instrument display; data transmission is radio-controlled, therefore wireless. Measurement data is printed on site on the IR printer.

635-2

The instrument for measuring air moisture, material equilibrium moisture and pressure dewpoint in compressed air systems. Moisture characteristics can be recorded in the instrument memory and analysed and displayed in graphics or tables. Up to 3 temperature or humidity probes can be displayed in the  635-2 meter; data transmission is by radio i.e. wireless. Selectable user profiles, i.e. allocation of specific function buttons and menu-guide to an application enable intuitive operation. Material moisture can be displayed immediately on account of the special probe. Characteristics for different materials can be stored in ComSoft and transmitted to the instrument.  635 immediately displays the dewpoint difference between ambient air and the wall surface in the analysis of moisture on walls and ceilings. Precision probes up to -60°C tpd are available to check pressure dewpoint in compressed air systems. The humdity sensor developed by Testo has proven itself worldwide and has outstanding features in terms of precision, long-term stability, temperature resistance and robustness.
