MAXMEEN OT-03 Multi-Parameter Online Water Quality Monitor

The MAXMEEN OT-03 is an advanced multi-parameter online water quality monitoring system designed for continuous and accurate measurement of water conditions in residential, commercial, and industrial applications.

The device simultaneously monitors Total Dissolved Solids (TDS), Electrical Conductivity (EC), pH, water temperature, and ambient humidity, providing real-time data before and after filtration systems. Equipped with a backlit LCD display, rechargeable battery, and calibration functions, the OT-03 helps users verify filtration efficiency and maintain optimal water quality.

Designed for reliability and ease of use, the OT-03 is suitable for Reverse Osmosis (RO) systems, water treatment plants, laboratories, aquaculture, hydroponics, and industrial process water monitoring.
