Product introduction
- This instrument is designed with imported pressure sensors, high precision ADC and low power consumption MCU.
- It features a professional digital pressure gauge with high precision, wide range, high resolution, large screen display and indoor temperature measurement; with a single channel, it is possible to quickly measure the current detection pressure value (relative to the current atmospheric pressure), whereas the dual channel allows simultaneous detection of the pressure difference between the two detection ports (P1-P2).

Precautions
- The instrument should be kept away from vibration sources, strong electromagnetic fields and areas with drastic temperature changes to avoid inaccurate data caused by vibration and electromagnetic interference, temperature fluctuations, etc.
- When measuring corrosive and toxic gases or liquids, please pay attention to protective measures to avoid personal danger or damage to the instrument.
- When the instrument remains low battery, please replace the battery in time. Please take out the battery when you don’t use the instrument for a long time, so as not to damage the instrument by liquid leakage.
- Please do not exceed the maximum value of input ±100kPa, when measuring the pressure of a single channel, please do not block the other channel, nor should it face the windy direction. At this moment, the instrument displays the differential value between the current measurement port and atmospheric pressure.
- When the interface displays over the range during measurement, please disconnect the vent, and then the displayed data will automatically back to normal; (The Pa unit can only be displayed up to 9999, and it can be switched to the next KPa unit).
- Please press and hold the HOLD button to clear the zero point drift of the data under the current mode before measurement (before connecting to the air tube).
