Dual-Probe Online TDS / EC Water Quality Tester – Digital Smart Monitor with I/O
A dual-channel online water quality tester designed for continuous monitoring of TDS and EC across two independent measurement points. Featuring dual probes, digital backlit display, and smart functionality with input/output capability, this system is ideal for water treatment, RO systems, aquaculture, and industrial process monitoring.
This digital dual-probe water quality tester provides real-time monitoring of Total Dissolved Solids (TDS) and Electrical Conductivity (EC) at two separate locations simultaneously. Designed for fixed installation, the system is ideal for applications requiring inlet/outlet comparison, filtration performance verification, or multi-stage water treatment monitoring.
The unit supports smart functionality and features a backlit digital display for clear visibility in low-light environments. With integrated input/output capability, it can interface with alarms, relays, or external control systems for automated response when preset thresholds are exceeded.
Common installation scenarios include:
-
Reverse osmosis (RO) systems (feed vs permeate monitoring)
-
Water purification systems
-
Aquaculture and hydroponics
-
Cooling towers and boilers
-
Industrial process water lines
-
Drinking water filtration systems
The dual-channel design enhances system diagnostics by allowing simultaneous comparison of water quality before and after treatment stages.
