High Temperature PH&ORP Sensor Manufacturer & Factory in Hanoi

Elevated process temperatures cause rapid leaching of standard glass membranes, which leads to sluggish response and significant measurement drift. Furthermore, temperature increases reference electrolyte expansion, creating risk of dilution or back-diffusion of contaminants. Our high-temperature sensors use specialized alkali-resistant lithium glass formulations and pre-pressurized solid polymer gel references that resist poisoning and physical degradation even during repeated steam sterilization (SIP) cycles.

Standard high-temperature sensors and digital transmitter systems are maintained in stock. For project deliveries in Hanoi, Bac Ninh, and surrounding industrial zones, air freight dispatched directly from Shanghai arrives at Noi Bai International Airport within 3 to 5 business days, clearing customs swiftly under standard ASEAN-China trade documentation (Form E certificate of origin support).

Yes. Our sensors utilize standard process connections including Pg13.5 threading, S8 and VP connectors, as well as 3/4" NPT threads. They are fully compatible mechanically and electrically with existing housings, immersion pipes, and transmitters from major international instrumentation manufacturers, allowing seamless retrofit without modification to plant piping.

In pharmaceutical and enzymatic fermentation processes, sensors undergo calibration prior to vessel autoclaving using traceable pH 4.01, 7.00, or 9.21 buffer standards. Following steam sterilization, an offline grab-sample validation with a calibrated laboratory pH meter allows for a simple 1-point process offset without violating vessel sterility.

All instruments are shipped with individual factory calibration certificates, CE conformity documentation, ISO 9001 and ISO 14001 compliance sheets, and Certificates of Origin (Form E) to facilitate zero-tariff import into Vietnam under bilateral regional trade frameworks.
