Product introduction

PH-1186 is a new generation of intelligent water quality detector independently developed by our company. It has the characteristics of Chinese menu operation, high stability, excellent repeatability, multi-function, etc. It can accurately measure the pH value/redox potential (ORP) and temperature value in the solution.

It is widely used in wastewater treatment, purified water, circulating water, boiler water and other systems, as well as in the online detection of PH/ORP values in the fields of electronics, aquaculture, food, printing and dyeing, electroplating, pharmacy, fermentation, chemical industry and other process areas. It has strong functions in environmental monitoring and remote system applications such as surface water and pollution source discharge.

main features

◇ Brand new waterproof, dust-proof and moisture-proof high-quality shell (IP65) technology, surface painting technology, generous and high-end appearance of the instrument.

◇ The product has high precision, high stability and strong anti-interference ability.

◇ Large screen dot matrix LCD display, support Chinese and English menus (mutual switching), simultaneous display of multiple parameters: simultaneous display of PH/ORP value, temperature, output current, alarm point, etc., which is intuitive and easy to read.

◇ Automatic temperature compensation function, which can manually correct PH and temperature values.

◇ Communication function: interface photoelectric isolation technology, with RS-485 communication interface (partially compatible with MODBUS protocol) (optional), which can convert RS-232. The PH value corresponding to 4-20 mA current output can be set at will, and 4-20 mA can be controlled both positively and negatively, which is widely used in some dosing fields. Support the company's internal Internet of Things and customized Internet of Things.

◇ The company's upper computer online acquisition software can be selected for data acquisition and processing.

◇ Notepad: PH/ORP mode can store 50 measurement data respectively, and users can record measurement data as required.

◇ Automatically identify the standard solution and restore the factory settings.

◇ Watchdog function: ensure that the instrument will not crash.

◇ Power failure protection > 10 years.

◇ The core components are from foreign brands.
