How to measure UV lamp illumination intensity?

See “Operation Manual” – “Chapter 4 Checking method of UV illumination intensity.

Instruments for illuminance measurement
* The following kits are optional.

OPT-J0288 Illuminance measurement kit (with illuminometer)
OPT-J0289 Illuminance measurement kit (without illuminometer)
* If you have a handy-type illuminometer for UJF-605C, the kit without illuminometer is necessary.

* The UV lamp is an consumable item.  As irradiation time increases, illumination deteriorates, and ink gets difficult to be hardened. When the accumulated irradiation time exceeds a certain value, a message is displayed on the operation panel, prompting you to check the illuminance.
