Laboratory Fast Pressure Instrument Verification Device
The IQS900-X Rapid Verification Device for Laboratory Pressure Instruments is an electronically controlled mind-controlled pressure calibration system. It enables pressure regulation modes including pressure rise, fall and halt by directly responding to the pressure calibration engineer’s conscious intent. This product has been granted a national invention patent application.
Designed to meet practical verification requirements, it streamlines cumbersome pressure calibration workflows, cuts verification time and improves work efficiency. It breaks away from both traditional manual pressure generation and conventional fully automatic pressure generation methods. As an innovative new rapid automatic pressure generation device, it adopts mind-controlled regulation, features a user-friendly design, and supports one-touch pressure control for pressure rise, fall and stop operations.


Product detail

The IQS900-X Rapid Verification Device for Laboratory Pressure Instrumentsis an electronically controlled mind-controlled pressure calibration system. It enables pressure regulation modes — including pressure rise, fall and hold — directly controlled by the pressure calibration engineer's conscious intent. This product has been filed as a national invention patent.
Developed to address real-world calibration needs, it simplifies cumbersome pressure calibration workflows, reduces verification time, and boosts work efficiency. Departing from both traditional manual pressure generation and conventional fully automatic pressure generation methods, this innovative new rapid automatic pressure generation device adopts mind-controlled regulation, features an innovative design for intuitive operation, and supports one-touch pressure control for rise, fall and stop functions.

Scope of Application

This pressure generation device is designed for the calibration and value transfer of pressure instruments, including:

  • Analog pressure gauges

  • Digital pressure gauges

  • Electric contact pressure gauges

  • Pressure transmitters

  • Differential pressure transmitters

  • Pressure controllers

  • Pressure switches

  • Tire pressure gauges

  • Oil-free pressure gauges

  • GMP differential pressure instruments for the pharmaceutical industry

  • Vacuum gauges for hospital negative-pressure inhalers

  • Acetylene pressure regulators

  • Furnace negative-pressure gauges for power plants

Key Features

  1. Built-in automatic pumpfor rapid pressure generation — no external air source required. Maximum pneumatic pressure up to 6 MPa; maximum hydraulic pressure up to 250 MPa.

  2. Simple operation— control target pressure freely and intuitively.

  3. Stable pressure controlwith fast readout response.

  4. Multiple protection functionsincluding built-in filter, gas-liquid separator, and one-touch blowdown — easily handles even heavily contaminated test instruments.

  5. Quick-pressure connectorsfor fast, convenient installation and removal of pressure instruments.

  6. Safe, reliable and durableconstruction.

  7. Adjustable pressure rate— both pressurization and depressurization speeds are adjustable.

  8. Operation mode— one-touch pressure control for rise, fall and stop; pressure control at your fingertips.

  9. Working ports— 4 × M20×1.5 female-thread quick-connect pressure ports.

Pressure Medium

Water or air is used as the medium for the pressure generator (pressure source). An innovative design allows direct use of tap water or purified water — the medium is widely available, easy to source, and clean. Contamination can be directly discharged without fear of clogging or fouling. This is particularly advantageous for secondary calibration of pressure instruments used in harsh environments in industries such as petroleum, chemical and construction. The medium is discharged after each use without recirculation, ensuring the calibration bench remains clean at all times.

Industries Served

Suitable for industries including:
Electric power, nuclear power, high-speed rail, metallurgy, petroleum, chemical, power construction, petrochemical construction, military, aviation, aerospace, shipbuilding, aircraft maintenance, gas fields, oil fields, metrology institutes / bureaus, third-party testing institutions, higher education institutions (teaching), factories, mines and enterprises, and pressure instrument manufacturers.
It provides pressure generation solutions for pressure instrument verification, calibration, teaching and research, improving pressure verification efficiency — representing an innovative new paradigm in pressure calibration.
