Uvicure Plus II & UV Power Puck II
Used in UV Conveyor Curing mostly on large area lamp systems in sheet fed or conveyor systems of inks, UV Adhesives, soldermasks and epoxies (not for use in web press applications).
The UV Cure Plus II (single band) and Power Puck II (four band) are easy to use anddisplay collected data in different configurations, including:
Power Puck® II Profiler and UviCure® Plus II Profiler
The “Profiler” versions of the Power Puck II/UviCure Plus II function as standard units with the added ability to transfer the irradiance profile to a computer.
The transferred data can be analyzed with EIT’s PowerView II/PowerView III Software to allow analysis, sharing, storage and comparison of readings. Profiler units offer ease of use on the production floor (display) with the display and ability to more detailed information when profiling capabilities are needed. The sample rate of the irradiance profile transferred to a computer is 128 Hz. Faster sample rates and a thermocouple are available with the EIT PowerMAP II. Batteries (AAA) are user changeable and instruments are available in 10 W/cm2, 1 W/cm2 and 100 milliWatt/cm2 ranges.
UV PowerMAP II
Designed to measure UV broadband sources in four (UVA, UVB, UVC, UVV) EIT spectral regions.
Profiling Radiometers such as the UV PowerMAP II provide an extensive “picture” of the UV source(s) and how the UV is delivered to the cure surface. The irradiance (W/cm2), energy density (J/cm2), irradiance profile (Watts/cm2 as a function of time) and the temperature profile (°C as a function of time) are available when the data is transferred to the computer.
Profiling radiometers quickly and easily identify:
- The number of lamps and bulb type in each position
- Lamp focus/Changes to the focus
- Process speed and/or exposure time variations
- Uniformity of the UV across bulb length
- The performance of individual lamps in multi-lamp systems
- Maintenance needs before they impact product quality
- System changes over time with the comparison to stored files
MicroCure Miniature UV Radiometer
An extremely small profile radiometer, both in diameter and height.
This small size allows it to be placed in tight areas and to work well for small container curing (cans, tubes, bottles). MicroCure gathers peak irradiance (W/cm²) and energy density (J/cm²) values which are then displayed on a small stand-alone DataReader. MicroCure is a disposable unit. After 200 readings or approximately one year (whichever comes first), replace your MicroCure with a fresh unit.
SpotCure UV Intensity Meter
An easy portable effective method of quantifying UV output.
The EIT SpotCure UV Intensity Meter is an easy portable effective method of quantifying UV output. It is a self-contained, electro-optic instrument designed to measure and display the intensity emitted by a UV curing system. Degradation of UV lamps, light guides, and reflectors can cause decreases in intensity and create curing problems. The EIT SpotCure UV Intensity Meter is designed to provide the operator with instant feedback as to the performance of the spot curing system
An ultraviolet UVC radiometer optimised for 254nm UV germicidal measurement in applications requiring high control of UV energy (dose) measurements.
Targeted applications include hospitals, medical offices, long term care facilities and research.
Advanced UV Monitoring System
The Compact Sensor from EIT is a breakthrough in UV sensor technology. It is extremely resistant to UV solarization in even the most intense UV fields. Solarization - the degradation of optical components caused by intense UV light - is virtually eliminated in the new design.
DIN Rail UV Intensity Monitor
An on-line, electro-optic instrument designed for monitoring a single UV lamp.
To get good curing results consistently, it is important to know when to perform UV system maintenance. Maintaining the cleanliness of the reflector is impot1ant to operate your UV system effectively and efficiently. If the lamps are only replaced at set time intervals, they may be replaced too soon or too late. Money is wasted if the lamps are still good. Product is wasted if the lamps are overdue for replacement. The human eye, unable to detect UV light, must rely on an instrument designed to monitor only UV within a specified bandwidth. An intensity monitor with a specific sensor will detect the output of a UV lamp continuously.
