Water Treat Plant PH Analyzer

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.
