Feature: 1. Non Destructive: The pressure gauge will automatically identify the device current and adjust the current to match without damaging the machine. 2. Accurate Measurements: The press uses a pressure calibrator for multiple null point, mid and full calibrations to ensure accurate measurements. 3. ABS Shell: Our pressure gauge is made of high density, non deformable and wear resistant ABS material, which is anti drop and can ensure the safety of the pressure sensor. 4. Handheld: Our manometers are small in size and can be handheld for easy portability and ease of work. 5. Application Range: The pressure gauges are widely used in natural gas pipelines, mechanical hydraulics, biopharmaceutical molding, mining areas, liquids and production industries. Specification: Item Type: Digital Manometer Material: ABS Model: TC 168A Battery: 1 x 9V 6F22 battery (excluded) Uses: Widely used in natural gas pipelines, air conditioning, refrigeration and ventilation systems, mechanical hydraulics, Hehe molding, ceramic products, biopharmaceutical molding, pressure testing in mining areas, petrochemical refining, natural gas, liquids and pressure testing in production industries.
