The Chemtrac DO Probe is the first of its kind in the world to offer automatic in-situ sensor verification as an option. The HydroACT 300 is able to reduce maintenance by automatically checking its sensor operation at user-defined time intervals. Calibration on the In-Situ sensor is normally required only once per annum so with the automatic sensor verification option and the self-clean option the sensor may not need to be inspected at all for a full year.

Overview
Principal of Operation
The sensing element (lumiphore) is activated or excited when illuminated with a blue light. When activated, the lumiphore emits red light in an intensity that is inversely proportional to the amount of oxygen present in the water. There is also a time delay between the peak emission of blue light and peak response of fluoresced red light. The amount of delay is inversely proportional to the amount of oxygen present. This time delay can be expressed as a phase shift between the wave patterns of incident blue light and the fluoresced red light. This is in turn reported by the electronics into a ppm or mg/l reading of Dissolved Oxygen. The advantages of this technology are that it is more stable than traditional electrochemical devices and far more resistant to abrasion. By using the state of the art sensor and electronics together the reliability, accuracy, and flexibility of the HydroACT 300 with DO Probe is far superior to that of its competitors.
In addition to the state of the art optical sensor the HydroACT 300 offers Modbus communications (TCP/IP, RS485), Relays and 4-20mA outputs. Despite all of the additional functionality that this unit has to offer, the purchase costs are less than or comparable to, its competitors. Added to the cost savings of a truly automatic sensor verification system, some will achieve a replacement payback of only a few months. Also available are Dual and Triple Validation options and various PID control functions.
