The BL 931700 mini pH controller is designed for easy, affordable installation in confined spaces to perform simple but effective process control. Thanks to its compact size, the BL 931700 can be installed right next to reservoirs and vessels. This versatile controller is ideal for a wide variety of applications such as textiles, paper, photographic solutions, coating of baths, chemicals and water treatment. BL 931700 is provided with an adjustable point for acid or base dosage. Measurements are immediately obtained from a pH electrode in the range of 0 to 14 pH with a resolution of 0.01 pH. Accuracy is ensured by the two-point calibration, performed manually by trimmers on the front. You can also choose between automatic or manual dosing via a switch at the front. Manual control is especially useful during maintenance work, because it allows you to switch the dosing relay on or off according to your needs. A time control system advises you when the relay is active for too long to help prevent overdosing. In addition, this model also has a 4-20 mA analogue output for registration connection.
