PHSJ-5T Laboratory pH Meter with 0.001 pH Resolution, ORP and Temperature Measurement

Product Overview
The PHSJ-5T Laboratory pH Meter is a high-precision benchtop instrument designed for laboratory measurement of pH, ORP (redox potential), mV, and temperature. It features a high-resolution color touchscreen, intelligent electrode and method management, multi-point pH calibration, automatic temperature compensation, and comprehensive GLP/GMP data management.
With 0.001 pH resolution, USB and RS-232 connectivity, USB flash drive support, and compatibility with an automatic sampler, the PHSJ-5T is suitable for routine laboratory analysis as well as regulated testing environments.

Key Features
• High-resolution color touchscreen with Chinese and English language support.
• Selectable pH resolution of 0.001, 0.01, or 0.1 pH and mV resolution of 0.01, 0.1, or 1 mV.
• Measures pH, ORP, mV, and temperature with automatic temperature compensation.
• Supports 1–6 point pH calibration and 1-point ORP calibration, with pH electrode diagnostics.
• Automatically recognizes six buffer solution groups, including GB, DIN, NIST, USA, MERK, and JIS, while also supporting customized standards.
• Intelligent endpoint recognition with automatic, timed, interval, or manual readings.
• GLP/GMP-compliant data management with storage, review, statistics, analysis, transfer, printing, and traceability functions.
• Supports automatic samplers, RS-232 printers, USB PC communication, USB flash drives, and barcode scanners.
• IP54 protection, power-off protection, automatic shutdown, firmware upgrades, and user permission management.

Working Principle
The PHSJ-5T determines pH by measuring the electrochemical potential generated by a pH electrode in the sample and converting the signal into a pH value. The instrument can apply automatic temperature compensation to improve measurement consistency under changing sample temperatures.
For ORP measurements, the meter detects the redox potential of the sample through an ORP electrode. Temperature is measured using a dedicated temperature electrode, allowing simultaneous monitoring and compensation during pH analysis.
The instrument supports multi-point calibration, buffer recognition, electrode diagnostics, endpoint detection, and measurement alarms to improve measurement reliability and data traceability.
