High-Temp (0-130°C) pH Sensor for Palm Oil & Chemical Systems in Malaysia
Industrial S8 Connector High-Temperature pH Sensor for Process Piping
Steam-Sterilizable CIP/SIP High-Temp pH Sensor for Biopharma Fermentation
Dual-Function High-Temperature pH & Pt100/Pt1000 ATC Integrated Sensor
Deploying liquid analysis in Peninsular and East Malaysia requires resilient engineering designed to withstand high tropical ambient conditions, corrosive volatile organics, and severe process fouling.
In regions like Sabah, Sarawak, and Johor, Palm Oil Mill Effluent (POME) digestion and crude oil clarification demand measurement at 80–105°C. Conventional porous liquid junction electrodes fail within 72 hours due to oil coating and junction clogs. Our solid polymer electrolyte and PTFE annular liquid junction prevent viscous oil ingress, maintaining measurement drift below ±0.03 pH per week.
Penang's advanced wafer fab clusters operate continuous hot chemical etching, CMP slurry loops, and toxic wastewater scrubbers. Sensors must operate in hot acidic or caustic baths containing hydrofluoric acid traces, where standard glass membranes dissolve. Our specially formulated alkali/acid-resistant glass glass bulbs ensure continuous drift-free readings with 4-20mA and RS485 Modbus RTU telemetry.
At massive integrated downstream complexes such as RAPID Pengerang and Gebeng Industrial Estate, high-pressure amine regeneration and sulfur recovery units run at elevated temperatures (110–130°C). BOQU high-temperature ORP and pH sensors utilize dual-chamber reference systems with polymerized KCl gel, resisting H2S and heavy cyanide poisoning while operating at up to 6 bar line pressure.

Metrological Repeatability Under Thermal Fluctuations
Why Tier-1 engineering procurement firms and regional Malaysian systems integrators choose BOQU as their long-term OEM/ODM manufacturing partner over costly European suppliers.
Standard measuring electrodes suffer glass dissolution and alkaline ion exchange errors at temperatures above 60°C and pH > 10. Our specialized low-impedance high-temp glass membrane retains linear Nernstian slope response (≥97.5%) up to 130°C, offering sustained durability through repeated CIP/SIP thermal cycles.
Liquid electrolyte electrodes fail when internal pressure equalizes with line pressure, resulting in process fluid backflow and reference poisoning. BOQU utilizes cross-linked polymerized KCl gel pressurized to 6 bar, preventing crystallization, eliminating internal bubble voids, and extending service lifespans 2.5-fold.
From precision blow-molding of metrological glass to custom automated surface-mount electronic assembly (SMT) for our IoT Modbus transmitter boards, BOQU's dual factories in Shanghai eliminate subcontracting markups, delivering 40-60% CAPEX savings with rapid air freight dispatch to KLIA and Port Klang.

Industrial automation directors across ASEAN, the Middle East, Europe, and the Americas are re-evaluating instrumentation supply chains in response to digital transformation and strict environmental enforcement.
Centralized DCS systems are replacing costly dedicated wall-mounted transmitters. Global plants require smart digital electrodes that transmit RS485 Modbus RTU directly to PLC rack modules or Edge IoT gateways. BOQU integrates internal micro-transmitters directly into sensor head assemblies for streamlined edge connectivity.
Malaysia's Department of Environment (DOE) rigorously monitors industrial effluents under the Environmental Quality Act (Industrial Effluent Regulations). High-temperature discharge lines cannot afford sensor drift or unexpected blind spots. Reliable online measurement protects operators against plant shutdowns and costly regulatory non-compliance fines.
Multinational chemical and EPC contractors are actively bypassing traditional brand distribution layers. Sourcing high-temperature electrochemical sensors directly from established Chinese manufacturers provides verified engineering quality, tailored OEM labeling, custom cable terminations, and significant operational cost reductions.
Practical guidance from BOQU application engineers on electrode installation, temperature compensation, and local implementation in Malaysia.
Standard electrodes feature thin glass compositions that dissolve or suffer hydration gel degradation when exposed to temperatures exceeding 60°C. Additionally, conventional reference chambers experience rapid electrolyte boil-off, Ag/AgCl dissociation, and internal pressure differentials that contaminate the reference junction. BOQU's high-temperature series uses low-solubility heavy-walled glass and pressurized polymeric solid electrolytes to guarantee thermal stability up to 130°C.
We maintain dedicated dispatch inventories for our standard high-temperature PG13.5 and 3/4" NPT threads. Standard orders are dispatched within 48 to 72 hours via DHL/FedEx air freight, typically clearing through KLIA or Penang customs within 3 to 5 business days. Every sensor ships pre-calibrated with a verified factory inspection sheet, along with NIST standard buffer powders for local verification.
ATC compensates solely for the Nernstian slope change of the glass electrode as temperature rises (ΔE = 2.303 RT/F). It does not alter the actual thermodynamic pH shift of the process liquid itself (such as neutral water shifting toward pH 6.1 at 100°C). For exact process control, BOQU online analyzers combine ATC algorithms with customizable solution temperature coefficient offsets.
Yes. BOQU electrodes are engineered with international standard mechanical form factors (PG13.5 insertion threads, S8/K8/VP6 connectors, and standard 120mm, 225mm, or 325mm glass shaft lengths). We provide seamless form-fit-function replacements that interface with your existing flow assemblies, retractable housings, and analytical transmitters without pipe modification.
In clean fermentation or steam sterilization processes, calibration verification is recommended prior to each production batch. In severe fouling environments, such as palm oil raw effluent or chemical crystallizers, cleaning cycles with mild 5% HCl or specialized surfactants every 1 to 2 weeks will maintain peak response speeds and prevent reference diffusion blockage.
Yes. BOQU operates full OEM and ODM manufacturing partnerships across Southeast Asia. We supply laser-engraved custom branding on sensor caps, specialized insertion cable lengths, customized range calibrations, and private-labeled multi-parameter analytical transmitters backed by comprehensive factory warranties.
