Dymax ACCU-CAL™ 160 UV Radiometer UV Intensity Meter

About Dymax ACCU-CAL™ 160 UV Radiometer

Consistent UV curing requires periodic monitoring of UV intensity or dose. The Dymax ACCU-CAL 160 radiometer greatly simplifies both validating and monitoring a light-curing process for both UV curing flood lamps and UV curing conveyor systems. This UV Intensity Meter is available in both UV and LED versions and can measure emitted light up to 10 W/cm2.

It can be used to determine intensity (measured in mW/cm²) or total energy as derived from intensity and exposure time (measured in mJ/cm²). The unit is simple to operate and can be controlled manually via four buttons on the faceplate or by a USB remote interface. Measurement results are displayed on the integrated LCD display or transmitted by the USB remote interface to a computer.

For intensity measurement of UV curing spot lamps, please see the ACCU-CAL 50 radiometer.
