The high temperature pH electrode is independently developed by BOQU with independent intellectual property rights. BOQU Instrument established the first specialized high temperature laboratory in China. Engineered specifically for aseptic applications, these hygienic pH electrodes perform reliably where Clean-in-Place (CIP) and Sterilization-in-Place (SIP) operations are frequently executed. They resist extreme temperatures and rapid media transitions, delivering uninterrupted precision measurements without requiring routine maintenance shutdowns.
Designed to ensure regulatory compliance across pharmaceutical, biotechnology, and food & beverage production lines, the sensor provides options for liquid, gel, and polymer reference solutions to optimize both measurement accuracy and operating life. Its high-pressure structure supports secure direct installation within industrial tanks, pipes, and reactors.

Equipped with standardized K8S socket and PG13.5 thread connection, enabling direct drop-in replacement for overseas brand electrodes.
Multiple insertion lengths offered (120 mm, 150 mm, 210 mm, 260 mm, 320 mm) to suit distinct process reactors and vessel sizes.
Designed for combined use with sanitary 316L stainless steel protective sheaths for robust hygienic process mounting.
Dedicated monitoring for amino acids, blood products, gene synthesis, insulin production, and interferon processing.
Strict continuous pH measurement during the synthesis and purification of antibiotics, vitamins, and citric acid.
Full-process analysis across brewing, mashing, boiling, fermentation, bottling lines, cold wort, and deoxygenated water.
On-line tracking for MSG, soy sauce, dairy manufacturing, fruit juice, yeast culture, sugar refining, and potable water.
Yes. The electrode is engineered specifically for hygienic processes with a temperature tolerance up to 130°C, allowing direct in-situ steam sterilization without compromising accuracy or life expectancy.
The sensor features a double liquid junction design with high compressive strength, safely operating under pressures up to 0.6 MPa even without external back pressure applied.
No. It utilizes heat-resisting gel and solid dielectrics that do not require replenishment, substantially minimizing maintenance frequency and downtime.
Yes. Built with standard PG13.5 process threads and a K8S socket (connecting to AK9 cables), it serves as a direct, seamless replacement for major overseas sensor brands.
The sensor is manufactured in multiple standard immersion lengths—including 120 mm, 150 mm, 225 mm, 275 mm, and 325 mm—to match varied tank and pipeline geometries when combined with 316L stainless steel housings.
It delivers full-range pH detection from 0 to 14 pH with an accuracy tolerance within ±0.1 pH across temperatures ranging from 0°C to 130°C.
