Testo 435-2 (CO and CO+CO2) | Indoor air quality meters to hire

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 Instrument Solutions Hire models come in two configurations; with the CO₂ IAQ probe only (for temp/humidity/CO₂), or with an additional ambient CO probe for extended monitoring applications.

Features

• Super-size memory for up to 10,000 readings at intervals from 1 sec to 1 hour.
• Displays dew point difference, min, max and mean values
• PC software for analysing and logging measuring data
