ZS-600 (circulation type)

Online Turbidity Meter

Range 0-500NTU, built-in bubble elimination system, with water storage function, 316 stainless steel shell, not affected by sample Flow velocity and pressure, two-point correction, can be customized range.

Introduction

Turbidity is the degree of obstruction that occurs when the suspended solids in the water pass through the light. The water contains soil, dust, fine organic matter and other microorganisms and colloids that can make the water appear turbid. After the light wave sent by the transmitter on the sensor is absorbed, reflected and scattered by the measured object during transmission, a part of the transmitted light can be irradiated to the Detector in the 180 ° direction, and a part of the scattered light can be scattered to the Detector in the 90 ° direction. The light intensity received by the Detectors in the 180 ° and 90 ° directions has a certain relationship with the turbidity of the tested sewage, so the turbidity of the sewage can be calculated by measuring the intensity of transmitted light and scattered light. This product uses the RS485 interface to communicate with the digital sensor, which has high data accuracy and strong anti-interference. It can directly control the calibration and automatic cleaning functions of the digital sensor.

Features

Large-screen dot matrix LCD display, support for Chinese and English menus (switch between each other).

◆ Built-in bubble elimination system (flow type) to improve measurement accuracy and stability.

Good reproducibility, unaffected by sample flow rate and pressure (immersion type).

The use of a stable invisible near-monochromatic infrared light source avoids the interference of liquid chromaticity and external visible light on the sensor measurement; and built-in photometric compensation to improve measurement accuracy.

It has a water storage function to ensure that the internal circulation tank of the sensor retains a water sample (circulation type) for 24 hours.

Adopt new detection technology to avoid interference from external light and have strong anti-interference ability (immersion type).

The use of a quartz glass lens with high light transmittance on the optical path makes the emission and reception of infrared light waves more stable.

Communication function (optional): With RS-485 communication interface (MODBUS protocol is partially compatible), the corresponding value of 4-20 mA current output can be set arbitrarily.

◇ Photoelectric isolation 4-20mA current output.

The hysteresis can be set arbitrarily to avoid frequent operation of the switch relay, and there are functions of setting the switch off and closing.

Adopt multi-point correction method.

The automatic cleaning interval can be set freely (sensor support is required).

The watchdog function: to ensure that the instrument does not crash.

The core components are all from foreign brands.

Power-down protection > 10 years.
