2026-06-11

1. High-Precision Sensing System for Simultaneous Multi-Parameter Detection

The CH200 Portable pH/ORP Meter developed by Shanghai Chunye Instrument integrates high-precision sensing, automatic temperature compensation, intelligent calibration and IP67 protection. It is a professional pH tester widely used in laboratories, industrial workshops, environmental monitoring, university experiments and other scenarios, delivering both superior detection accuracy and excellent on-site practicality.

Equipped with a high-performance electrode sensing unit, the meter features a wide measuring range: pH range from -2.00 to 20.00 pH with an accuracy of 0.01 pH; ORP range from -2000 to 2000 mV with an accuracy of ±1 mV. It also enables real-time temperature measurement for one-stop reading of multiple parameters. The foolproof electrode connector allows easy plug-and-play and stable connection, effectively preventing connection failures.

2. Dual-Mode Temperature Compensation for Environment-Insensitive Accurate Data

Adopting mature automatic temperature compensation technology, the instrument corrects data deviations caused by temperature changes in real time. It also supports manual temperature setting and fine temperature offset adjustment, adapting to complex environments with high or low temperatures and ensuring accurate and reliable readings under various working conditions.

3. Global Multi-Point Calibration & Intelligent Electrode Status Monitoring

The meter is built with multi-point calibration functions and preloaded with four major standard buffer solution systems adopted in China, the United States, Europe and Japan. It supports automatic identification and multi-point calibration for pH measurement and two-point calibration for ORP measurement. The system intelligently monitors electrode conditions and reminds users of maintenance or replacement in a timely manner, maintaining stable accuracy during long-term operation.

4. IP67 Protection Design for Diverse Complex Working Conditions

The whole device meets IP67 dustproof and waterproof rating, capable of withstanding liquid splashes, humid conditions and harsh outdoor environments. Lightweight and portable, it runs on AAA batteries and features a 10-minute auto power-off function for extended battery life.

5. Comprehensive Intelligent Functions for Easier Operation & Data Management

It is equipped with a backlit display, reading hold function, and storage & browsing for up to 255 sets of data. One-touch switching between pH and ORP modes is available for simple operation and traceable data. With fully configurable parameters, robust protection and low failure rate, the device boasts complete functional configurations.

Featuring solid core technologies and comprehensive functions, this waterproof pH/ORP meter is a cost-effective preferred choice for water quality detection applications.
