Suntex TC‐7320‐RS and TD‐200 series is designed for measuring lower range turbidity in clean water. The well designed, accurate system provides resolution capability up to 0.0001 NTU.
There are EPA compliant traditional tungsten lamp sensor and long‐life white LED sensor models for choice.
The transmitter can connect with up to two turbidity sensors and provides all analog & digital outputs and relay controls under a great user‐experience operation interface.
Features
- The tungsten lamp sensor model, TD‐200, compliant with EPA regulations
- The long‐life white LED sensor model, TD‐201, requires almost no light source replacement
- Both models ensure that the measurement is not disturbed by water mist
- Built‐in sophisticated bubble removal device ensures reliable measurement
- Easy operation, dual channel, analog and Modbus output transmitter
Applications
- Drinking Water
- Boiler Water
- Raw Water of Beverage Industry
- Membrane Fouling Monitoring
