Description
Features
- Measures pX or pH, ORP, conductivity, TDS, salinity, Resistivity, dissolved oxygen, saturation and temperature
- Adopts LCD display and Chinese operation interface
- Has manual or automatic temperature compensation
- Provides zero oxygen and full-scale calibration
- When meter measures conductivity, it switches frequency automatically to guarantee measuring accuracy
