The NGM2611 is a pre-calibrated module for natural gas alarms which is precisely calibrated in Figaro’s humidity and temperature controlled facility. The module uses TGS2611-E00 which incorporates a filter to eliminate the influence of interference gases such as alcohol, resulting in highly selective response to methane.

The most important process in manufacturing reliable residential gas alarms is adjusting the alarm point. Calibration is a complicated and time consuming process which also requires a substantial investment in calibration equipment. By eliminating the costly calibration process, this module enables users to easily and simply manufacture residential natural gas alarms. Figaro has taken the complexity out of designing a gas detector circuit by providing users with a temperature compensation circuit which combines a built-in thermistor and individually adjusted load resistor together with Figaro’s low power methane gas sensor.

A connector allows easy replacement of the module for the purpose of periodic sensor renewal. This input/output connector enables easy installation of the module into the gas detectors’ mother board. This same mother board can be used for both methane and LPG gas detectors by simply changing the module.
