Product Description
Apera Instruments PH850 Series
Application-Specific Portable pH Meter Kits
The Apera Instruments PH850 Series represents a specialized line of professional portable meters engineered to solve the most difficult pH measurement challenges in the field, laboratory, and factory floor. While standard general-purpose pH probes rapidly drift, clog, or physically break when exposed to harsh or unconventional matrices, the PH850 Application-Specific series eliminates these failures. By pairing a highly rugged, water-resistant handheld meter with specialized electrodes tailored to distinct physical and chemical environments, this series guarantees rapid stabilization, long-term accuracy, and extended operational lifespan.
Designed for industrial resilience, the PH850 portable meter features an ergonomic, impact-resistant chassis built to endure the rigors of mobile environmental and agricultural testing. The internal microprocessor delivers advanced digital processing, ensuring that whether you are piercing a solid cut of meat on a processing line, testing boiling caustic fluids in a chemical plant, or analyzing micro-volumes in a clinical setting, the instrument provides reliable, traceably stable data. The intuitive interface allows operators to easily navigate multi-point calibrations and track electrode slope health.
The true power of the PH850 Series lies in its expansive range of variant configurations. From titanium-bladed spear probes for solid foods to hydrofluoric acid (HF) resistant glass sensors for the semiconductor industry, each kit is purpose-built. To maximize immediate utility and laboratory efficiency, every application-specific variant is supplied as a complete, ready-to-deploy kit housed in a hard carrying case containing the meter, the specialized probe, and all necessary calibration buffers.

Key Performance Features
- Matrix-Matched Technology: A highly diverse range of probes ensures that operators never have to force a general-purpose sensor into a hostile testing environment.
- Rugged Handheld Design: The meter chassis is built to withstand impact and moisture, securing internal electronics during heavy industrial and field use.
- Intelligent Automatic Calibration: Quick and seamless multi-point calibration system with automatic buffer recognition saves time on the factory floor.
- Comprehensive Field Kits: With the exception of the base PH850-A model, all variants arrive in a secure carrying case complete with the meter, specialized probe, and necessary calibration standards.
- Stable 8-Pin Connectors: Utilizes a secure, threaded 8-pin connection ensuring that temperature and pH signals are transmitted without interference, even during rigorous physical movement.
- Customizable Base Option: The PH850-A provides a flexible foundation (meter and temperature probe only) for laboratories that already utilize specialized Apera 8-pin LabSen electrodes.
