The testo 435 is perfect for monitoring, analyzing and diagnosing indoor air quality problems in the office, in the warehouse, or on the production floor, in restaurants or schools... anywhere you need to take important IAQ measurements.
You can easily pinpoint and troubleshoot problems with HVAC systems and see the results of corrections immediately. Commissioning, validating, benchmarking, or simpy adjusting HVAC systems are all easy with the testo 435.
All the right parameters for HVAC and IAQ
A new IAQ probe measures CO2, relative humidity, room air temperature and absolute pressure for evaluating indoor air quality. In addition the 435 can calculate absolute
The testo 435 is designed to accept a variety of probes depending upon your applicaton. The extraordinatory selection makes it possible to measure everything from IAQ to velocity.
For basic HVAC checks, temperature and humidity measuremenst have been integrated in the new thermal probe, for measurements in ducts. Flow speed, volume flow, air humidity and air temperature can easily be measured in one sequence.
The vane probe with a diameter of 2.4 in. is suited for integrated measurements at registers. For duct measurements, a 0.6 in. vane probe with a broad range, 118 to 8000 fpm is available. The Pitot tube is ideal for higher air
velocities. A 10”H20 differential pressure probe is integrated into the testo 435-3 and testo 435-4 for this purpose.
For important IAQ measurements the unique IAQ probe measures CO

, relative humidity and room air temperature in order to evaluate room air quality plus absolute pressure.
The degree of air velocty or draftiness in any room can easily be determined with the turbulence probe. Determine the true illumination (lux) of those low-lit areas that affect working conditions daily.
Surface temperature measurements of motors, cooling coils, heat exchangers, etc. are easily performed with the cross-band probe. Its unique design reaches the actual surface temperature in just a few seconds.
pressure, draft, lux and surface temperature. Determining volume flow, is easy with a wide selection of thermal probes, vane probes and Pitot tubes.
The right probe for every application

Wireless probes offer many advantages over traditional cable or integrated probes. Measurements up to 65 ft. from the meter are possible. There is no risk of damaging or tangling wires or cables. With the teso 435 up to three wireless probes can be read and displayed at once for temperature and humidity measurements. The optional wireless module can be installed by the user at any time.

The test 435 was designed from the ground up to provide easy-to-follow ,menus and a large, clear display. For measurements at different locations, the 435-2 and 435-4 can assign measured values to user-defined and named locations in the memory.
Programmed functions
Important measuremetns such as mean calucations (both “timed” and multi-point”), and area inputs for volume flow calculations, are directly accesed by the three function buttons. Any area input (circle or rectangle) can be stored in memory or modified at point of use. Five pre-determined shapes are accessible via the
Designed for the way you work
You want your instrument to be accurate and dependable. The testo 435 was designed and built as a precise and rugged instrument with an IP54 protection rating. The rubberized case material provides shock and impact protection. The large, back-lit display is recessed to provide added protection. An integrated loop on the top is available for a carry strap. Plus, integrated magnets on the instrument back provide secure hands-free operation. The testo 435 delivers laboratory-level accuracy, with toolboox toughness and versatility.

function buttons.
Long-term IAQ measurements of indoor air parametes are simple via the function buttons. Different measurement programs can be pre-set in memory and called up as needed.

The testo 435 offers several options for viewing, managing, printing and analyzing data.
The simplest option is to print out data with date and time for convenient and fast documenation on-site with the optional testo infrared printer.
With the 435-2 and 435-4 measure and store up to 10,000 readings then analyze them via Testo’s ComSoft3 Compact Software (included). Easily display your data in graphs or tables, or export the data to a spreadsheet for further analyses.
In addition the testo 435 can perform timed interval printing from 1 minute to 24 hours using its user-specified “Cycle printing” function for longterm monitoring.
