ZhongKe TK PC-302M Handheld Multi-Parameter Water Quality Analyzer

Features

Multi-parameter measurement: Simultaneously measures four parameters: dissolved oxygen, pH, mV, and temperature;

Automatic identification: Intelligently detects and automatically identifies various electrode models and calibration values for pH and dissolved oxygen;

Intelligent measurement: Supports automatic calibration, data storage, function settings, and power reminders;

Automatic compensation: Features temperature calibration and automatic temperature compensation to compensate for the effect of temperature on electrode slope, ensuring accurate and reliable measurement results;

Backlight function: Backlight function adapts to complex environments and features an automatic shut-off function for energy saving;

Extended functions: Dedicated APP operating system enables more extended functions;

Multiple power supply options: Supports AA batteries and Type-C power supply;

Portable protective design: IP67 protection rating for the main unit and IP68 for the electrodes; optional portable protective carrying case.
