Achieving reliable calibration at low pressure ranges demands specialized equipment designed for exceptional control and sensitivity. Standard pressure generation tools often lack the necessary resolution, as even minute volume changes can induce significant pressure fluctuations in the millibar, Pascal, or inches of water column range. Our low pressure calibration solutions address this through features like fine volume adjusters integrated into hand pumps, allowing technicians to approach and stabilise set-points with extreme precision, which is critical when verifying the performance of sensitive instrumentation.
These systems often include high-accuracy digital pressure indicators, serving as practical secondary reference standards within a calibration laboratory or workshop. The accuracy of these indicators is paramount, ensuring that calibrations performed on devices such as differential pressure transmitters for cleanrooms, HVAC flow sensors, or low-pressure switches for medical equipment meet stringent performance criteria. Using a high-accuracy reference ensures traceability and confidence in the measurements performed by the field or process instruments being calibrated.
Generating and controlling very low air pressures, sometimes down to fractions of a pascal, requires test pumps engineered for this specific task. These pumps incorporate mechanisms that provide highly sensitive adjustment, enabling users to precisely dial in specific low-pressure points without overshoot. This level of control is indispensable for technicians calibrating magnehelic gauges, validating leak detection systems, or performing R&D testing on components sensitive to minute pressure variations, ensuring accurate and repeatable calibration results even at the lowest detectable pressures. The stability of the generated pressure is just as important as the precision of the setting, allowing sufficient time for the device under test to settle and be accurately read.
