Industrial online pH Controller instrument NP-1806 Industrial waste water pH test
Product introduction
Np-1806 is a new generation of intelligent water quality detector independently developed by our company. It has the characteristics of English menu operation, high stability, excellent repeatability and multi-function, and can accurately measure PH value, REDOX potential (ORP) and temperature value in solution. It is widely used in waste water treatment, such as pure water, circulating water, boiler water system and electronic, aquaculture, food, printing and dyeing, electroplating, pharmaceutical, fermentation and chemical processes in the field of PH/ORP value on-line detection, in the surface water and pollution emissions and other environmental monitoring and remote power system applications.

Main features
● Waterproof, dust proof, moisture-proof (IP65), high-end design look.
● high precision, high stability and preferable antijamming ability.
● Large screen LCD display, support Chinese - English menu (switching from each other).
● Automatic temperature compensation function, manual adjustment of PH and temperature value.
● Communicate function: RS-485 communication interface with photoelectric isolation (optional, MODBUS protocol partially compatible), convertible RS-232. Two 4-20mA current outputs, corresponding to temperature and PH value respectively, the PH value corresponding to the first 4-20mA current output can be arbitrarily set, and the PH range can be inversely corresponding to the 4-20MA range; the other way 4-20mA current output defaults to 0-130 °C. It is widely used in automatic addition of reagent.And it also support to connect loT of company and customize loT for customer.
● With automatic cleaning function, use running water to cleaning device.
● Optional with the company's host computer online acquisition software for data acquisition and processing.
● Note book: It can store 50 PH measurement data and 40 ORP data, users can record measurement data as needed.
● Historical curve: It can record 50 sets of PH historical data and 40 sets of ORP data (sampling time- interval is 1-240minutes), and has a query function.
● Automatic identification of standard solution and capable for factory reset.
● Watchdog function: make sure the meter doesn't crash.
● Power off protects > 10 years.
