AUTOOL Digital Differential Manometer Hand-held Air Pressure Gauge Negative Vacuum Press Gauge Meter

AUTOOL Manometer Professional Air Pressure Meter with Two Differential Pressure Gauge Input Ports HVAC Gas Pressure Tester

This AUTOOL digital manometer uses imported pressure sensors, a high-precision ADC, and a low-power MCU. It features a professional digital pressure gauge with high precision, wide range, and high resolution. The large screen display shows pressure and indoor temperature. The single channel measures the current pressure value relative to atmospheric pressure. The dual channel detects the pressure difference between two ports (P1-P2) simultaneously.

Warm Tips

• Keep the AUTOOL digital manometer away from vibration sources, strong electromagnetic fields, and areas with drastic temperature changes. Vibration and electromagnetic interference can cause inaccurate data. Temperature fluctuations may also affect accuracy.
• When measuring corrosive and toxic gases or liquids, please pay attention to take protective measures to avoid personal danger or damage to the instrument.
• When the instrument reminds 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 ±20KP/52kPa/89kPa/52kPa/89kPa, when measuring pressure .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.
• If the interface shows an over-range during measurement, disconnect the vent. The displayed data will automatically return to normal. The Pa unit can only display up to 9999. It will switch 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).

Product Usage

• This product can be widely used in natural gas pipelines, air conditioning, and refrigeration systems.
• It is also suitable for mechanical hydraulics, plastic molding, and ceramic manufacturing. The product works in biopharmaceutical molding, mining pressure testing, and petrochemical industrial smelting.
• It detects pressure in gas, liquid, and industrial equipment, as well as liquid levels.
• Additionally, it is useful for laboratory calibration and micro-pressure testing in medical environments.\
