This product comes with a one-year warranty from the date of shipment, lifetime maintenance, and periodic inspection and calibration services, provided that there is no human damage.

Measurement:
Press the power switch to display the instrument information and enter the main measurement interface. The dew point temperature, volume ratio, absolute humidity, gas flow rate, date and time, and battery power of the current gas measurement value will be displayed separately. The instrument takes about 10 minutes to initialize before entering the measurement state.
At this point, adjust and stabilize the flow rate of the measured gas at 1.0L/min to 3.0L/min, and then connect the measured gas to the instrument through a self-locking quick connector; Alternatively, the flow rate of the measured gas can be turned off first, and the measured gas can be connected to the instrument through a self-locking quick connector. Slowly adjust the flow rate of the measured gas to stabilize at 1.0L/min to 3.0L/min. The instrument defaults to nitrogen gas as the measured gas.

In the measurement state, after the instrument displays stable data, the instrument indicates the current measurement value. After the measurement is completed, unplug the self-locking quick connector and turn off the power.
