Introduction

                                       

Thank you for purchasing a ENV Series monitoring device. This manual explains how to install and setup the product.

Before the installation and use of the product, carefully read the supplied instructions.

The ENV Series Temperature, Humidity & CO2 device monitors the conditions of a room or space, these include temperature (°C), humidity (%RH) and carbon dioxide (ppm).

Specifications

Measurement Range Accuracy Notes
Temperature -40°C to +125°C ±0.3°C  
Relative Humidity 0% to 100% RH ±2% RH Non-condensing environment
CO2 0 to 5000 ppm ±50 ppm +3% of reading  

Calibration

Temperature and humidity sensors can be supplied with UKAS traceable or UKAS certified calibration, depending on customer requirements.

Calibration should be carried out at intervals defined by your internal procedures, risk assessments, or applicable standards.

The inbuilt CO₂ sensor features an automatic background calibration function.

Following installation and power-up, the sensor will automatically calibrate over an initial period of approximately 48 hours, provided the monitored environment allows exposure to typical background CO₂ levels.
