Ph Meter Sensor by BOQU

Product Overview

The PH5806/K8S is a high-temperature, hygienic pH sensor from BOQU designed for demanding industrial and aseptic processes. It is independently developed with proprietary IP and supported by BOQU’s dedicated high-temperature laboratory. The sensor provides full pH measurement across 0.0–14.0 pH with an accuracy of ±0.1 pH and is available in probe lengths of 120/150/225/325 mm (12 mm diameter). Rated for use up to 130°C and up to 6 bar (0.6 MPa), it is built for in-situ cleaning (CIP) and sterilization (SIP) environments.

Product Features

- Hygienic construction with FDA-certified sanitary design for pharmaceutical, biotech and food applications.

- Heat-resistant gel dielectric and solid dielectric double liquid-junction structure for stability at high temperature and rapid media changes.

- Options for liquid, gel or polymer reference solutions to balance accuracy and lifetime.

- Low-maintenance design with compatibility to replace METTLER TOLEDO and Hamilton electrodes.

- Cable/K8S connector (AK9 cable) and no additional dielectric required.

Product Value

The PH5806/K8S enables reliable, continuous pH control and regulatory compliance in processes that require frequent CIP/SIP and operate at elevated temperatures. Its robust, low-maintenance design reduces downtime and maintenance costs while extending sensor life. Compatibility with common top-brand electrodes and multiple reference options helps protect existing investments and simplifies integration.

Product Advantages

- Proven high-temperature performance (up to 130°C) and high-pressure capability suitable for tanks and reactors.

- Hygienic, FDA-compliant construction tailored for aseptic production.

- Independent R&D and local high-temperature lab testing ensure quality and traceability.

- Factory-direct supply from BOQU gives competitive pricing and responsive service.

- Minimal maintenance requirements and interchangeable replacement with similar international sensors.

Application Scenarios

Ideal for fermentation tanks, biotechnology and pharmaceutical manufacturing, food & beverage production, starch paste processing, and other industrial processes requiring sterile/high-temperature pH monitoring. Especially suited to installations where in-situ cleaning/sterilization (CIP/SIP), fast media transitions, or elevated temperature/pressure conditions are routine.
