High-precision, 7-inch TFT display, 1000 sets of data storage, setting menu can customize 17 functional parameters, the meter is suitable for measuring pH and ORP values of samples, measurement accuracy 0.002pH.
pH mode
High-precision pH meter with 7-inch TFT display.
Optional pH buffer standard (USA/NIST/DIN) or 5-point custom calibration.
Automatic electrode diagnosis with electrode slope and offset display.
Automatic temperature compensation ensures high-precision measurement over the full scale range.
Solution Temperature Coefficient (STC) compensates for pure water measurements and converts readings to 25°C.
The alarm limit automatically warns whether the measured value exceeds the set range.
ORP mode
1 point offset calibration allows adjustment of the displayed value to a known standard.
Relative and mV modes provide accurate ORP readings.
General Features
Calibration due reminder prompts the user to calibrate the meter regularly.
Automatic endpoint locking retains stable measurements for easy viewing and recording.
Interval reading mode periodically sends measured values to a PC or printer.
Password protection prevents unauthorized calibration and setup.
Extended memory can store up to 1000 sets of data.
USB communication interface is easy to connect external devices.
One-key reset automatically restores the meter to the factory default settings.
