The Testo 435 is the preferred instrument for today' professional air balancing contractors, commissioning experts and building energy management specialists. Quickly and easily verify system performance to provide real time BTU/hour readings.

The deal choice for measuring ambient air conditions, assessing Indoor Air Quality, and evaluating VAC systems. The Testo 435-1 is an affordable means for measurement engineering of ambient air conditions. The new IAQ probe measures indoor air CO2 levels, moisture, and temperature. Temperature and humidity measurements are integrated into the new thermal probe. Optional temperature probes may be utilized based on the needs of your applications. Readings from up to 3 temperature probes can be viewed simultaneously on the display and printed on site with the Testo printer.

Your instrument should 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, impact protection, and a comfortable grip. The large, backlit display is recessed to provide added protection and visibility. In addition, integrated magnets on the back provide secure hands free operation. The testo 435 delivers laboratory level accuracy and dependability, along with toolbox toughness and versatility.

Applications:

Air Balancing Analysis
Air flow traveses oin ducts
IAQ Siagnostics
V/AC system performance testing
U-Value/R-Value determination

435 Features:

Accepts a wide variety of wired/wireless probes for airflow, pressure, temp. %RH, CO, and CO2.
Performs timed and multi point averaging as well as CFM, BTUh calculations
Internal preecision pressure sensor available
Data logs up to 10,000 readings (optional)
Integrates readings of up to 3 wireless temperature/humidity probes

The newest technology for temperature, humidity, air flow and more!

Easily pinpoint and troubleshoot problems with HVAC systems and see the results of corrections immediately. Commissioning, validating, benchmarking, or simply adjusting HVAC systems are all easy with the new Testo 435 Series HVAC Performance Test Kits.

The right probe for every application.

The extraordinatory selection makes it possible to measure everything from IAQ to velocity. For basic HVAC checks, temperature and humidity measurement 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.
