Gas Sensors

1 Series

The 1series analogue gas sensor is compact low profile sensor utilizing the trusted City Technology. These sensors have an extended operating life of five years along with extended temperature and humidity ranges

Overview
Citytech 1 Series sensors

Honeywell 1Series gas sensors are unique, compact square sensors designed to meet the global requirement for thinner, more lightweight gas detectors. At 1/3 the height of traditional gas sensors, the 1Series has turrets to mount into the front of an instrument to minimize instrument height. The revolutionary design simplifies target-gas access to the sensor face and features an option for a replaceable external membrane.

1Series sensors target the following gases: carbon monoxide, hydrogen sulfide, oxygen, sulfur dioxide, and combustible gases.

These gas detector sensors are often fitted within instruments, such as portable life safety devices and industrial gas leak detectors. 1Series gas sensors excel in challenging and extended temperature and humidity extremes, such as those found in industrial gas applications.

Engineered with an operating life of five years, Honeywell has designed the sensor platform for the future.
