High Temperature PH&ORP Sensor Manufacturer & Pricelist in Hungary

In standard bioprocess applications undergoing 121°C–130°C SIP cycles (typically 30–45 minutes), calibration should be verified before each sterilization cycle using freshly prepared, certified NIST or DIN buffers (pH 4.01 and 7.00). After sterilization, allow the vessel and sensor to cool to process temperature (e.g., 37°C) before taking an offset grab-sample check. With BOQU high-temperature lithium glass, zero-point shift is typically under 0.05 pH after 20 consecutive autoclave cycles, drastically reducing the need for aggressive mid-batch recalibration.

Standard PG13.5 threaded sensors with S8 or VP6 (Variopin) connectors allow maintenance technicians to detach and replace an exhausted probe in under two minutes without pulling 20 meters of cabling through conduits back to the control cabinet. The VP6 connector also routes both high-impedance pH signals, reference signals, and dual Pt100/Pt1000 temperature wires through an IP68 hermetically sealed plug, preventing moisture and corrosive condensation ingress common in humid Hungarian food and pharmaceutical cleanrooms.

Yes. BOQU high-temperature sensors are engineered with standard European mechanical dimensions (PG13.5 mechanical thread, 12mm shaft diameter, and insertion lengths of 120mm, 225mm, 325mm, and 425mm). Electrically, our analog probes output standard mV/pH Nernst signals compatible with transmitters from Knick, Endress+Hauser, Mettler-Toledo, Yokogawa, and Bürkert. Our digital models support open Modbus RTU (RS485), connecting directly to PLCs without vendor lock-in.

Hydrogen sulfide reacts with free silver ions (Ag+) to form insoluble silver sulfide (Ag₂S), which clogs ceramic junctions and causes massive potential drifts (often >100 mV). BOQU addresses this by using silver-ion-free electrolyte in the outer chamber of our double-junction probes, paired with a solid polymer matrix. This creates a tortuous diffusion barrier that prevents sulfide ions from reaching the internal Ag/AgCl reference element, extending sensor service life from 2 weeks to over 6 months in thermal wells.

Standard high-temperature catalog models are held in inventory for dispatch within 48 hours. Express air cargo (via DHL/FedEx) to Budapest Liszt Ferenc International Airport takes 4 to 6 business days. For containerized project orders or system integration panels, multimodal air/rail freight delivers to central logistics hubs in Budapest or Székesfehérvár within 14 to 20 days, supported by full export declarations (EUR1/CO, commercial invoice, CE compliance declaration).
