ST-L508B industrial online conductivity meter can be widely used for continuous monitoring of conductivity values/TDS in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

ST-L508B Industrial Online Conductivity Meter

Industrial online conductivity meter is an online intelligent conductivity/TDS meter independently developed by our company. Using high-performance CPU chips and SMT surface mount technology to measure conductivity/TDS and temperature, temperature compensation, and automatic range conversion, with high accuracy and good repeatability. It can be widely used for continuous monitoring of conductivity/TDS in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.

Features:

◇ Large screen dot matrix LCD display, Chinese menu operation.

◇ It can measure conductivity/TDS, control upper and lower limits, automatically switch the range of standard current transmission, and improve the measurement resolution of the product.

◇ The screen displays the alarm status and can be accompanied by ON/OFF signal output at the same time.

◇ Automatic temperature compensation function: automatic 0-100 ℃.

Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol), the conductivity/TDS value corresponding to 4-20 mA current output can be set arbitrarily.

Watchdog function: Ensure that the instrument panel does not crash.

The core components are all from foreign brands.

◇ Factory settings can be restored. Power failure protection>10 years.
