On-line PH Meter With RS485/RS232 Output For Sewage Treatment
On-line PH meter with RS485/RS232 output for sewage treatment
Introduction
This product is a new - generation intelligent water quality detector independently developed by our company. It features English menu operation, high stability, excellent repeatability and multiple functions. It can accurately measure the pH value and temperature value in solutions. It is widely used for the online detection of pH values in solutions in fields such as environmental protection, sewage treatment, thermal power generation, aquaculture, food processing, printing, metallurgy, pharmacy, fermentation, chemical industry and tap water.
