Frequently Asked Questions

ABP2 or HSC Series with appropriate pressure range. High resolution (14-bit) and low total error band accurately detect pressure changes between clean and clogged filters.

Yes, MIP Series is designed for refrigerants including R134A, R407C, R410A, R448A, R32, and R1234ze with media-isolated construction.

Board mount (ABP2, HSC) are for dry, non-corrosive gases with digital output. Media-isolated (MIP) use hermetic sealing for aggressive media like refrigerants.

Implement auto-zero calibration at system startup. Take a zero-pressure reading before starting the fan to eliminate sensor offset errors.

MTTF of 1.7 million hours (194 years) at 10-30°C. Long-term drift is 0.25-0.35% FSS per 1000 hours, eliminated via auto-zero.
