Online water Suspended Solids TSS Controller ZS-680 Water quality analyzers TSS meter
Product Introduction

Online water Suspended Solids TSS Controller ZS-680 Water quality analyzers TSS meter
Main Features

• Large screen dot matrix LCD display, support Chinese and English menu (mutual switching).
• Built-in bubble elimination system (flow-through type) to improve measurement accuracy and stability.
• Good reproducibility, not affected by sample water flow rate and pressure (submerged type).
• Using a stable invisible near-monochromatic infrared light source, avoiding the interference of chromaticity in the liquid and external visible light on the sensor measurement; and built-in luminosity compensation to improve measurement accuracy.
• Featuring water storage function to ensure that there are water samples in the circulation tank inside the sensor for 24 hours (flow-through type).
• Using the latest detection technology to avoid the interference of external light, strong anti-interference ability (submerged type).
• Using quartz glass lens with extremely high light transmittance on the optical path, the transmission and reception of infrared light waves are more stable.
• Communication function (optional): With RS-485 communication interface (partially compatible with MODBUS protocol), the value corresponding to 4-20 mA current output can be set arbitrarily.
• Photoelectric isolation 4-20mA current output.
• Relay lag value can be set freely, avoid frequent action of switch relay, and with function of setting the replay on and off.
• Using multi-point correction method.
• The automatic cleaning interval can be set freely (only sensor support that ).
• Watchdog function: to ensure that the meter will not crash.
• Power off protection>10 years.
