BL981411-1 : PH MINI CONTROLLER

Features

• The BL 981411 pH controller has been designed for easy, affordable installation in tight spaces, ideal for simple and effective process control. 
• The unit is provided with high impedance pH input and can be used with any pH electrode with standard BNC connector. 
• Measurements are clearly displayed on the LCD, while the status LED indicates operating mode.
• BL 981411 is also provided with a dosing relay. Selecting acid dosing, will cause the relay to activate when the measurement is higher than the set point. 
• If the basic dosing is selected, the relay is activated when the reading falls below the set point.
• Set point adjustment (from 0 to 14 pH) and calibration procedures are easily performed with trimmers on the front panel. 
• Users can choose from automatic or manual dosing modes with a switch on the front panel. 
• Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need. 
• An overtime control system advises users when the relay is active too long, to help prevent overdosing.
