1. Application

Monitoring of pH in many different industrial processes to reduce cost and optimize yield, especially in harsh conditions such as municipal wastewater and industrial wastewater.

• Water/wastewater treatment

•Inflow of the plant, water collection well, aeration tank, the effluent, etc.

• Pulp and paper, power plant, mine

•Water treatment, chemical treatment feeding

2. Features and Benefits

• The maintenance of electrode is easy and low cost, the reference system repels dirt and rarely clog.

• No electrolyte refilling is required, it can be used under the condition of the max pressure 6bar.

• Strong anti-interference by sulfur.

• History curve function: the measurement data is collected every 5 minutes, data can be stored for one month.

• Notepad function, provides the record of operating and alarming time.

• When the electrode is calibrated, the mode, time and results are recorded, easy to review and analysis the change.
