PH8.0 pH Controller, ORP Controller for Industrial, Laboratory pH Value Control/Monitoring
Introduction
This advanced pH controller integrates a 4.3-inch display with bilingual (Chinese/English) interface, supporting manual or automatic temperature compensation via NTC10K, PT1000, or PT100 probes. It features high input resistance (≥10^12 Ω) and operates effectively in temperatures from 0 to 60°C, with storage capabilities from -20 to 70°C at 10-85% relative humidity (non-condensing).
The device includes data recording for up to 100 sets using the FIFO method, configurable intervals, and automatic cleaning functions with adjustable timing. Compatible with various electrodes, like glass electrodes for pH, platinum for ORP, or antimony alternatives alongside NTC10K, PT1000, or PT100 temperature sensors, it provides LED indicators for relays and cleaning, along with navigation keys for easy setup.
Operating principle
Step 1: The pH8.0 lineup pH controller/ORP Controller operates by interfacing with pH, ORP, or antimony electrodes to detect solution potential differences, converting these into readable pH or ORP values.
Step 2: Temperature sensors provide real-time data for compensation, adjusting measurements to account for thermal effects on ion activity.
Step 3: Signals are processed through an internal circuit, enabling output via analog currents, digital communication, or relays for process automation and alarms.
