Jiangjing Technology Electric Contact Pressure Gauge Metrological Verification and Calibration Equipment Intelligent Pressure Calibrator

I. Portable Pressure Instrument Rapid Verification DeviceProduct Overview:

The IQS800-X Portable Pressure Instrument Rapid Verification Device is an electrically controlled, thought-operated pressure calibration device that allows pressure calibration engineers to control pressure rise, fall, and stop operations through their own thought processes. This product has been applied for a national invention patent. Designed to meet actual calibration needs, it simplifies cumbersome pressure calibration procedures, saves calibration time, and improves work efficiency. It replaces traditional manual and fully automatic pressure generation methods with an innovative, user-friendly design that enables one-button control of pressure rise, fall, and stop operations through human thought control.

It is suitable for calibrating and value transfer of pressure instruments such as analog pressure gauges, digital pressure gauges, electrical contact pressure gauges, pressure transmitters, differential pressure transmitters, pressure controllers, pressure switches, tire pressure gauges, oil-free pressure gauges, GMP differential pressure instruments in the pharmaceutical industry, hospital negative pressure suction vacuum gauges, acetylene pressure reducers, and furnace negative pressure gauges in power plants.

Medium Source:

Using water or air as the medium for the pressure generator (pressure source), the innovative design allows direct use of tap water or purified water. The medium source is广泛, convenient, and clean, allowing direct排污 without fear of dirt or clogging. This is particularly advantageous for secondary calibration of pressure instruments used in harsh environments in industries such as petroleum, chemical, and construction. After each use, the medium is directly discharged without recycling, ensuring the calibration bench remains clean.

Applicable Industries:

Suitable for industries such as power, nuclear power, high-speed rail, metallurgy, petroleum, chemical, electrical construction, petrochemical construction, military, aviation, aerospace, shipbuilding, aircraft maintenance, gas fields, oil fields,计量 (院)所, third-party testing agencies, higher education teaching, factories, mines, enterprises, and pressure instrument manufacturers. It provides pressure generation devices for pressure instrument verification, calibration, and teaching research, improving pressure verification efficiency and representing an innovation in pressure calibration methods.
