Differential Pressure Gauge Calibration in Bangladesh
ION Engineering calibrates differential pressure gauges used for filter monitoring, flow and level applications against traceable dual-port reference standards, accredited to ISO/IEC 17025:2017.
What We Calibrate
Filter Monitoring Gauges
DP gauges used to monitor filter and HVAC pressure drop.
Flow-Related DP Gauges
Differential pressure gauges used in orifice-plate flow measurement.
Cleanroom DP Gauges
Room-to-room differential pressure gauges for cleanroom and pharma facilities.
How We Calibrate a Differential Pressure Gauge
Known pressures are applied to both the high and low ports from a traceable reference source, and the gauge’s differential reading is recorded as-found and as-left across its working range — the correct method for an instrument that measures a difference, not an absolute value.
What’s included
- Dual-port calibration across your working range
- As-found and as-left readings
- Stated measurement uncertainty
- QR-verifiable certificate
Differential Pressure Gauge Calibration FAQs
Can this be calibrated in a cleanroom without disrupting the pressure cascade?
Yes, our engineers can calibrate room-to-room DP gauges on-site following your gowning and entry procedures.
How often should filter DP gauges be calibrated?
Annually is common, though HVAC and cleanroom filter monitoring gauges are sometimes checked more frequently given their role in classification compliance.
What measurement uncertainty do you report?
Uncertainty is stated per range on your certificate; our full accredited scope is published on our calibration capabilities page.
Is the certificate independently verifiable?
Yes, every certificate number can be checked using our online verification tool, with no login required.
