The AJX-2 Methane Detector Calibrator is a metrological standard device used for verifying and calibrating gas detectors, gas alarms, gas cut-off devices, and gas telemetry systems. Composed of the XY series standard gas cylinders, pressure gauges, and rotor flow meters, the AJX-2 Gas Detector Calibrator features compact size, light weight, simple operation, easy maintenance, and portability. It is suitable for use by gas instrument metrology verification departments, factories, mines, ventilation laboratories, scientific research and educational institutions, as well as industries such as railways and petroleum. According to user requirements, with minor modifications, this device can also serve as a supply source for carbon monoxide, carbon dioxide, oxygen, and other gases.
