    What types of gas detectors does General carry?

    We carry combustible gas, refrigerant, carbon monoxide, VOC, and formaldehyde detectors.

    How often do these meters need to be calibrated? How do you calibrate them?

    We do not have a standard as to when these meters need to be calibrated. In order to calibrate the meter, it needs to be sent to a lab. We do not perform calibrations.

    How long are the sensors good for?

    The lifespan of the sensor depends on the usage and levels of exposure.

    Can I test carbon monoxide detectors using car exhaust?

    The extremely high concentrations of carbon monoxide from the exhaust would damage the sensor in our detector, model # DCO1001.
