1、 Application

Widely used in sewage treatment, discharge monitoring, and sludge concentration monitoring in fields such as water supply plants, paper mills, and electricity.

2、 Product Features

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

The instrument can change different ranges to improve flexibility.

Multi beam RD measurement technology compensates for the effects of ambient light, dirt, and component aging.

◇ Two point calibration ensures accuracy within a wide measurement range.

◇ Output of various variables such as current and relays, and intelligent control of the system.

Various installation methods such as immersion and pipe insertion.

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

Communication function: Interface photoelectric isolation technology, with RS-485 communication interface (partially compatible with MODBUS protocol) (optional), can convert RS-232.4-20 mA current output corresponding to sludge concentration value can be set arbitrarily.

◇ Optoelectronic isolation with 4-20mA current output.

◇ The function of setting the hysteresis value arbitrarily avoids frequent actions of the switch relay, and has the function of setting the switch value to turn off and off.

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.

◇ ABS plastic shell IP65, waterproof, dustproof and moisture-proof design.
