The Testo 435 is a multifunctional instrument which is ideal for IAQ monitoring as it can for a wide range of parameters including carbon dioxide (CO2), carbon monoxide (CO), temperature and humidity.
The IAQ version is available to purchase in a standard kit configuration and it can log up to 8147 readings at intervals from 1 sec to 1 hour.
The Instrument Solutions Hire models come in two configurations; with the CO2 IAQ probe only, or with an additional ambient CO probe for extended monitoring applications.
- Comprehensive range of measuring functions using optional accessories – e.g. anemometers, moisture sensors, lux and degree of turbulence sensors
- Super-size memory for up to 10,000 readings
- Displays dew point difference, min, max and mean values
- PC software for analyzing and logging measuring data
