　　2. Product Introduction

　　Key Features:

　　◇ New waterproof, dustproof, and moisture-proof shell (IP65) technology, surface painting technology, and elegant appearance of the instrument.

　　The product has strong anti-interference ability.

　　◇ Large screen dot matrix LCD display, supports switching between Chinese and English menus, and displays multiple parameters simultaneously.

　　◇ It can measure conductivity/TDS, control upper and lower limits, and automatically switch ranges to 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: Both RS485 and 4-20mA interfaces use optoelectronic isolation technology. The RS-485 communication interface is compatible with the MODBUS protocol (optional) and can be converted to RS-232. The conductivity/TDS value corresponding to the 4-20 mA current output can be set arbitrarily. Support internal IoT and customized IoT for customers.

　　◇ Function of setting hysteresis arbitrarily to avoid frequent operation of switch relays.

　　◇ Can be customized in large quantities (within 0-300 mS · cm-1)

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

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

　　24-hour real-time monitoring
