GEW Innovations Cut Costs for Customers
The hand-held unit is a specialist scientific instrument, which is inserted into a docking station in the front door of the lamphead to measure the UV intensity in milliwatts per square centimetre (mW/cm2). Where measuring the intensity of UV, or any light source for that matter, the positioning of the sensor in relation to the lamp is critical to obtaining accurate and repeatable results. If a sensor is located in three different positions, it is likely to give three very different readings. GEW’s solution involved designing a precision-engineered docking station and corresponding probe to ensure that the sensor is always in exactly the same position relative to the lamp, so that the only variable that can possibly be measured is the lamp’s UV output. The unit itself is capable of storing readings from up to sixteen lamps in its internal memory, which can then be downloaded to a computer via a USB cable. A line graph can then be plotted to show how the intensity of each lamp changes over time, and thus indicate when it is time to replace the lamp. The effects of cleaning the reflectors and glassware can also be measured quantifiably.
