Hanna Instruments Process Division has released the mV 602 line of microprocessor controllers, engineered to incorporate ease of use with a set of features. These robust instruments can be configured to use P, PI or PID controlling. The user does not need to choose from three separate instruments that each only allow one configuration.
The mV 602 line includes models that incorporate control through analogue output to drive compatible devices such as electrovalves or pumps. Several models have bidirectional RS485 to allow remote operation with a PC as well as analogue recorder output. The fully-programmable microprocessor memory has a three-month backup power supply. The fail safe alarm system protects against power interruption or line failure. Use of a solid state relay has been included to meet the needs of extreme industrial applications. All models incorporate a differential input so a grounding bar may be attached, extending the life of the electrodes by eliminating ground loop current problems.
Each mV 602 model is supplied complete with mounting brackets and instructions.
