Products Description
It is widely used in wastewater treatment, pure water, circulating water, boiler water system, etc. And online monitoring of ORP value, such as electronics, aquaculture, food, printing and dyeing, electroplating, pharmaceutical, fermentation and chemical processes. It is very powerful in the application of remote systems and environmental monitoring of surface water and pollution source discharge.
Product Features
main feature |
The newly designed housing is waterproof, moisture-proof and dust-proof. |
It has automatic cleaning function, and the cleaning device (optional) is in tap water cleaning mode. |
Two channels 4-20mA, corresponding to temperature and PH respectively. |
The product has high precision, high stability and strong anti-interference ability. |
Large dot matrix LCD screen, supports English operation menu, and displays multiple parameters simultaneously. |
Automatic temperature compensation and adjustable pH and temperature values |
Communication function: Opto-isolated 4-20 mA current output, the corresponding value can be freely set. |
You can choose to use our company's host online acquisition software to collect and process data |
Historical curve: PH mode can record 50 sets of historical data (sampling interval 1-240 minutes), and has query function. |
Automatically identify standard solutions and restore to factory settings. |
Watchdog function: ensures that the instrument has not crashed |
