testo 435 Portable Multi Function IAQ, CO2, Vane and Hot-Wire Anemometer and NTC Thermometer

The new testo 435 is available in four versions with a wide selection of probes for many different applications plus wireless technology for more remote monitoring. The models range from the basic 435-1, a standard IAQ and HVAC multifunction meter to the 435-4, the most advanced, compact meter in the family. The 435-4 has a built-in micromanometer and measures temperature, Rh, CO2, and barometric pressure with an intelligent four function IAQ probe. A large memory capacity is able to safely store 10,000 readings which can be downloaded and analyzed later for diagnostics and audits. In addition, the 435 can calculate absolute pressure, draft, and has probes for lux and surface temperature.  Determining volume flow from 0 – 8000 fpm is easy with a wide selection of thermoanemometer probes, vane probes and Pitot tubes. A valuable option is the unique wireless probes which allow simultaneous measurements of temperature and humidity from up to 65 feet away. These probes operate with the same accuracy as traditional cable probes without tangled wires or integrated probes without limited measuring capabilities. Up to three wireless probes can be read and displayed at once and the optional wireless module can be installed by the user at any time. Use the ComSoft3 software for analysis, filling and documentation of measurement data. For field documentation purposes, the 435 will print values with time & date to an optional infrared printer.  It can perform timed interval printing from 1 minute to 24 hours set by the user.
