Abstract
A thermostatic module of a compact gas sensing device and a compact gas sensing device are disclosed. The thermostatic module includes a housing unit, a thermal insulation unit, a heat conducting unit, a temperature sensor, a heater and a control circuitry board. The thermal insulation unit is placed inside a first accommodation space provided by the housing unit, and forms therein a second accommodation space in which the heat conducting unit is placed. The interior of the heat conducting unit forms a third accommodation space where gas sensor modules can be housed, and also a gas passage channel. The heater generates and transfers heat to the heat conducting unit, whose interior temperature is constantly probed by the temperature sensor and input to the control circuitry board which dynamically adjusts the heating power by the heater to make sure the measured temperature is always stabilized around a preset target value.
