In most UV systems, monitoring of UV-C irradiance is essential to ensure disinfection on water treatment systems or to ensure the effect on photochemical processes. The UV probes used for these measurements are exposed to high-energy UV radiation, which may cause aging effects. Due to that, periodic testing and recalibration is required to meet different regulations. ÖNORM M5873-1 recommends a certification validity and recalibration interval of one year.

The internal digital processing of the ZED digital ballasts and D-sensors combined with digital communication interfaces allows the constant monitoring and control of all important parameters in UV systems.

Besides the UV measurement value the ZED TinyMeter enables access to sensor specific data: sensor-ID, operating hours and date of last adjustment/calibration. Exceeding the specified operating hours of a connected reference sensor is indicated in the display.

The ZED SmartMeter is a comfortable operating and display device in the form of common handheld radiometer. It provides a graphical measurement-progress indicator to evaluate the temporal stability of the values. The measured values can be recorded over a defined period using the data logging function.
