An easy, portable, effective method of quantifying UV output
As UV spot curing technology has evolved, it has become increasingly important to establish a method of measuring system performance. The EIT SpotCure Radiometer is an easy, portable, effective method of quantifying UV output.
This UV intensity meter is a self-contained, electro-optic instrument designed to measure and display the intensity emitted by a UV spot curing system. Degradation of UV lamps, light guides, and reflectors can cause decreases in intensity and create curing problems. The EIT SpotCure Radiometer is designed to provide the operator with instant feedback as to the performance of the UV curing system.
Configuration: This UV radiometer is totally portable, self-contained, and battery-operated using a special lithium battery stick for extremely long life—in excess of 100,000 readings. The measurement head, which contains the optics, is attached to one end of the cylindrical instrument. Light guide adapters that fit into the measurement head are available to fit most size light guides. The instrument can be configured to read one of the following UV transmission bandwidths: 250–260nm, 280–320nm, 320–390nm or 395–445nm.
Operation: The EIT SpotCure is simple to use. Its compact, flashlight-like shape (4.60” long by 1.74” diameter) can comfortably be gripped in one hand.
In operation, the instrument is gripped in one hand while the light guide is inserted with the other hand. Once a UV spot curing system’s light wand is inserted into the measurement head, the user depresses the “START” switch and a measurement is taken. When the “START” switch is released, the measurement is frozen and can be viewed on the LDC display. It will be held for approximately three minutes until the display times out or until the user depresses the “START” switch again.
Adapters insert into the measurement head to accommodate the standard light wands on the market. This flexibility allows the instrument to be used in a variety of monitoring applications. Short, simple operation instructions are printed on the outside of the instrument.
The EIT SpotCure Radiometer is designed to withstand the rugged UV environment and extremely high intensities that can be associated with UV spot curing. It can monitor UV intensities up to 20W/cm2 for the standard version and 200W/cm2 for the extended range version.
The EIT SpotCure meets ISO 9000 requirements.
