Detailed introduction

Product Features

Universal controller—no need for multiple dedicated controllers; automatically recognizes digital sensors and supports plug-and-play operation.
The dual-channel design allows connection of either one or two sensors, reducing user costs and providing a cost-effective solution for future expansion to a second sensor.
4.3-inch full-view color display with quick switching between digital readout mode and real-time curve mode for easy monitoring of data fluctuations. Optional NB-IoT wireless communication allows real-time data viewing via a mobile app.
It can measure a wide range of parameters, including pH, ORP, conductivity, dissolved oxygen, turbidity, sludge concentration, residual chlorine, ammonia nitrogen, nitrate nitrogen, COD, and more.
It features both manual temperature adjustment and automatic temperature compensation, with the latter supporting four calibration solutions—linear, ultrapure water, acidic, and alkaline—enabling it to accommodate a wider range of operating conditions.
