The testo 435-4 multifunction meter is perfect for monitoring, analyzing, and diagnosing indoor air quality issues. Users can easily pinpoint and troubleshoot problems with HVAC systems, immediately seeing the results of actions. Commissioning, validating, benchmarking, or simply adjusting HVAC systems are all easy with the testo 435-4.
The testo 435-4 multifunction meter allows you to carry out all the measurements that are necessary to check and adjust HVAC systems, and to assess the quality of indoor air. The 435-4 accepts a wide variety of probes to measure and record airflow, humidity, temperature, and indoor air quality (IAQ) readings. And with the included ComSoft Software, this data can be organized by location, analyzed, and reported.
Probe dependent menus and selectable user profiles ensure that the testo 435-4 multifunction meter is always ready to use. Easy setup of user defined IAQ and airflow / duct profiles allows for fast measurement of many different tasks. And with a wide variety of probe choices available, the testo 435-4 is ready to handle a vast array of HVAC and IAQ applications. The superb data handling will keep your readings organized and ready, however you need them, whether in a quick printout on-site, or for further analysis and placement into a report.
Improved convenience of operation thanks to user profiles
The operation of testo 435 is easy and efficient - User profiles are stored for the typical applications of duct and IAQ measurement. This makes complicated programming of the instrument unnecessary.
Secure measurement data monitoring
Measurement data reports provide the customer with data from the duct, long-term and degree of turbulence measurement. The company logo can be integrated into the form, and measurement values can be printed on the Testo fast printer.
Flexibility thanks to wireless probes
In addition to classical probes on wires, a wireless measurement up to a distance of 65 feet (without
obstruction) is possible. Damage to the wire or hindrances in usage are thus eliminated. A maximum of
three wireless probes can be recorded and displayed with testo 435. The optional, easily plugged-in
radio module can be retrofitted at any time.
