Functional Features
Measurement process controlled by MCU, with digital filtering technology to enhance system reliability.
Manual and automatic temperature compensation, using digital temperature compensation technology to eliminate non-linear factors in temperature compensation.
Three-point calibration function.
Simultaneous measurement of pH or mV and temperature.
During calibration, only the nominal value of the buffer solution at 25°C needs to be entered, and the instrument automatically identifies and compensates for temperature.
High-performance, ultra-low-power 16-bit microcontroller with high-capacity rechargeable lithium battery.
Data protection against power loss ensures data is not lost, with storage capacity for 999 data sets with time tags.
Auto-lock mode: The display automatically locks onto stable readings.
Type-C port for data transfer to a computer.
Large LCD screen with Chinese character menu display for convenient and intuitive operation.
The instrument has good corrosion resistance, waterproofing, and dustproofing.
