UM33A YOKOGAWA digitale indicator

I purchased the genuine Yokogawa FU20-VP-T1-NPTFPS all-in-one pH/ORP sensor (PN 55411138) for our wastewater treatment process monitoring, and its performance far exceeded my expectations. This 4-in-1 integrated design supports simultaneous pH, ORP and temperature reading with built-in Pt1000 compensation, which eliminates extra wiring work for separate temperature probes. The PVDF rugged body and double-junction reference with ion trap greatly resist chemical fouling and poisoning in our corrosive waste liquid, cutting down our sensor replacement frequency by half compared to old brands we used before. The integrated NPT thread fits our pipeline perfectly, and the VP variopin connector makes cable connection neat and anti-interference. Readings stay stable even under long-time continuous operation, calibration drift barely occurs for months. The supplier shipped original unit with full calibration certificate, on-time delivery, will reorder bulk quantity for our new production lines.
