Features:
Package includes:
digital vacuum gauge, portable tool bag, brass expansion connector, user manual
Sensor cleaning:
During the procedure, it is possible that the sensor is polluted by foreign matter, and then you need to clean the sensor follow these instructions:
1. Turn off the vacuum gauge, and remove all the batteries
2. Shake out the foreign matter
3. Using an eye dropper or a syringe fill the sensor chamber with alcohol or isopropanol, tighten the copper cap and then rinse the sensor chamber for 3-4 times with alcohol isopropanol
4. Thoroughly dry the sensor by vacuumization or at least 2 hours of air dry
5. Inspect the vacuum meter and make a Zero Calibration

Specification:
Connection: 7/16-20 UNF(1/4"Flare)
Maximum overload pressure: 14 PS1/ 0.1 Mpa
Range: 0-10000Pa, 0-100.00mBar, 0-75.000mmhg, 0-75000Micro
Resolution: 0.01(Accuracy: 2-100Pa: ±5% of reading(at 20°C)
Operating temperature: 0-50°C(32-122°F)
Connection: 7/16-20UNF(1/4'' Flare)

Note:
1. Measure the vacuum level according to the instructions and within the parameters specified in the manual
2. Do not use any corrosive cleaners or any solvents to clean the department
3. Please Wear goggles and protective gloves before operation it.
4. Tighten the copper cover and store it in a dry place
5. It cannot be used for measurements in non-atmospheric environments (the readings in refrigerant or other gas environments will be inaccurate. If measured in a non atmospheric environment, the accuracy will return to normal after it is placed in the atmosphere for 24 hours)
6. Professional use only. Need a vacuum chamber and a 0.1Pa standard diaphragm vacuum guage are required to complete the zero calibration. Zero calibration will be completed before shipment to ensure the accuracy of each vacuum gauge
