Product Description

Core processor uses advanced ARM Cortex M3 (32-bit), which make the processing performance more stable and efficient;
 Wide, large LCD display clarity (dot matrix LCD), tri-color backlit prompt different states;
 Four function keys, sensitive, fast (confirmed, return, up and down, left and right);
adopted Electrochemical sensors, ADC uses 24 high-precision chip;
 pump-priming Sampling way,and control and display flow rate by rotameter; (optional, with no positive pressure pump, vacuum with pump)
 MCU memory to store max 500 historical data;
  the Communication way to connected to the host computer is RS485;
 Audible alarm so you can not ignore the prompt;
 Compatible with conventional control output: 4 ~ 20mA current one-way, two-way relay, sound and light alarm output;
 Compatible software and hardware calibration.
