GEW’s DoseGuard Laboratory Unit is the perfect quality control system for any pressroom with multiple GEW UV-equipped machines. It offers a fast, simple and accurate method to measure the UV output of any GEW UV Arc or LED cassette across its entire width under standard conditions. The system can analyse any GEW cassette manufactured since 2000.
How does the DoseGuard Laboratory Unit work?
The DoseGuard sensor is mounted inside the Lab Unit, below the lamp mounting position. When a cassette is inserted, the Lab Unit will run the lamp at the selected power level and scan the entire length of the lamp. Irradiance in mW/cm2 is measured and UV dose at any speed is calculated for easy comparison of expected curing performance. Warning levels can be set to easily identify non-conforming cassettes and data can be simply exported via USB in Excel format.
What’s included?
All units include a cassette housing, a power supply, a heatsink, a fan and a touchscreen for operation.
UV cassettes are provided by the customer from the production systems to be analysed.
An ozone filter can be included as an optional extra, enabling the Lab Unit to be used stand-alone without the need for any extraction ducting.
