GT781 PH and ORP
This professional instrument measures the oxidation-reduction potential in solutions by detecting the potential difference between electrodes. It reflects the relative proportion of oxidized and reduced substances in the solution and is widely used in water quality monitoring, industrial production, and scientific research experiments.
The ORP meter can measure pH values, solution temperature, and sensor voltage, making it a versatile tool for various analytical applications.
- Dual probe capability: pH probe measures pH value, temperature, and sensor voltage; ORP probe measures REDOX potential and temperature
- Automatic/manual data recording with report generation
- Solution temperature compensation for pH measurements
- Comprehensive data storage, viewing, and deletion functions
- Adjustable sampling time intervals
- Configurable automatic shutdown timing
- pH self-calibration with multiple calibration point options
- Selectable temperature units (°C/°F)
- Factory settings restoration capability
- Adjustable screen brightness
- Chinese/English language selection
- Low battery alert and battery level monitoring
- USB charging capability
- PC software connectivity for data transfer
- Generates CSV and BMP files compatible with Windows systems
- Functions as a small-capacity storage device (USB flash drive)
