Multi Water Quality Meter consists of sensor probe to measure each water quality contents and handy logger to retrieve the monitoring data.

Standard water quality contents are five (5) items that are pH, DO (dissolved oxygen), EC (electrical conductivity), temperature and turbidity, and total maximum 10 items can be optionally increased.

Compact design is applied and these instruments are portable. Hence, it is useful / reasonable for water quality check in the dam reservoir and lake. Also, low power consumption design contributes to realization of continuous monitoring in a borehole for the groundwater quality check.

User can expand this stand-alone monitoring system to remote monitoring system using GSM i-SENSOR data transfer unit smoothly/reasonably.



Feature
  • Salinity, TDS (total dissolved solution) and ocean water gravity is converted from conductivity.
  • pH sensor has pressure compensation function and applies Strong-pH electrode with toughness.
  • DO sensor applies no motion DO electrode which makes possible to measure at no fluid flow.
  • It can be installed in 50 mm PVC pipe because of the compact design.
  • Because of low power consumption design, power source is only three (3) pieces of marketed AA batteries and 1 month continuous monitoring is available.
