WQS-CB -- NB-IoT/LTE-M Water Quality Sensor Converter

The Dragino WQS-CB is a Main Unit is advanced instruments designed for comprehensive water quality monitoring across various applications. They are ideal for monitoring tap water, industrial water, environmental water, and wastewater,etc,which ofer precise and reliable measurements to ensure water quality standards are met.

The Dragino WQS-CB is a Main Unit supports 1-3 probes. supports connecting 1 to 3 water quality probes, including EC, pH, DO, ORP, and TS probes.

 It detects water quality parameters, and uploads the value via wireless to NB-IoT/CAT-M1 Server.

WQS-CB supports BLE con­figure and wireless OTA update which makes user easy to use.

WQS-CB is powered by 8500mAh Li-SOCI2 battery , it is designed for long-term use up to several years.
