Widely used in environmental protection, sewage treatment, thermal power, breeding, food processing, printing, metallurgy, pharmacy, fermentation, chemical industry, water and other solution PH value of the online detection.
1.All adopt the imported chips and components, using the latest table paste production process, to ensure that the instrument is stable and reliable in work.
2.It shows more parameters: at the same time it can also show PH value, temperature, high alarm set value, the low alarm Settings, instrument whether in high or low alarm condition, and the current time. All the parameters be clear at a glance.
3.Second-ranking unique 4 ~ 20 mA current output corresponding to the PH of both reversible and can be set to any value, can bring more particularly convenient to users.
4.The waterproof and air seal shell, it can be used in very harsh environmental conditions, protection grade reaches IP65.
5.Second-ranking RS485 communication (optional)
6.Low electrode automatic cleaning function (optional)
7.Unique history curve function, which can record the current 30 days of historical data query functions.
8.Unique design, low operation menu has brought great convenience to users, users can use freely even if don't look at the instructions.
9.If three minutes no keystrokes backlight will automatically shut off, power saving and can prolong the service life; The screen contrast level is adjustable.
