Hazardous Gas Controllers and Sensors

Controllers & Sensors for CO, CO2, O2, Refrigerant and
Hazardous Gases, Duct mount Smoke Detectors, Air Quality Sensors
Dataloggers for monitoring Hazardous & Toxic Gases



Our HVAC B.U. has a strong presence in the measurement and control of gases, air quality and leak detection to ensure that buildings are compliant with the NZ standards. In particular we offer a range of fixed sensors for monitoring Carbon Monoxide (CO) & NO levels in underground car parks, hazardous & combustible gases in industrial work environments, and a comprehensive range of refrigerant & gas leak sensors.

E+E offer a comprehensive range of wireless transmitter solutions for CO2/rH/degC control and monitoring and the HUMILOG20 series data loggers for CO2/rH/degC measurement.
Critical Environmental Technologies (CETCI) gas detectors are used to detect many different gases. Some of the most common are carbon monoxide, carbon dioxide, nitrogen dioxide, nitric oxide, ammonia, chlorine, ozone, combustible gases like methane and propane, oxygen, refrigerants and more.

We are excited to announce the arrival of the new Critical Environment Technologies cGas Detector product line. The new sensors offer greater flexibility with customized sensor combinations and specialized options for HVAC&R applications. Importantly for our customers, the cGas Detectors provide an aesthetically pleasing and cost effective option to other sensors in the market.

An aesthetically pleasing enclosure designed to deliver continuous monitoring of hazardous gases while reduce noticeability of the device in publicly frequented areas such as hotels, hospitals, schools, apartment buildings, retirement homes, auditoriums and more. View datasheet here.

The cGas Detector is a one or two gas channel digital transmitter that offers greater flexibility at a lower cost with customized sensor combinations and specialized options for adding only the functionality you need. It is ideal for monitoring toxic, combustible and refrigerant gases in commercial and light industrial, non-hazardous (non-explosion rated) environments. View datasheet here.

The cGas Detector Carbon Dioxide Transmitter is a low maintenance gas monitoring device designed for use in non-explosion rated, commercial applications that require continuous monitoring of CO2. View datasheet here.
