Jelight Company also sells and services meters to measure ultraviolet light. Our portable handheld instrument units are battery operated, lightweight, and easy to use. Jelight Company also offers different types of probes that can be purchased separately to meet your specific measuring application.
JLT5000 Radiometer
The JLT5000 is improved upon the industry standard radiometer with rapid measurements (up to 100Hz), a broader dynamic range (100 fA to 1 mA), extensive supporting software apps, wireless communication, internal data storage, and a 4-20 mA output.
The broad linear dynamic range of the JLT5000 and the SMA input connector allow the meter to also serve as a broad-range, highly sensitive and accurate range pico ammeter.
The JLT5000 supports numerous light measurement applications including, but not limited to: Radiometry, Photometry, Research, UVGI- Sterilization, Solar, Photoresist, Optical Radiation Hazard , Photo-therapy, Photo-degradation, Plant Growth, and more…
Ultraviolet Meter JLT1000
The most versatile UV, VIS, and IR datalogging optometer available on the market today. The JLT1000 design is backed by a number of years of light measurement experience and comes complete with NIST traceable, ISO 17025 accredited calibrations.
The JLT1000 was designed with customer configuration in mind and can easily accommodate most solid-state detectors, 1/2” and 1” optical filters, and a vast selection of input optics.
The JLT1000 is capable of measuring over 6 decades of light and providing direct readout in W, W/cm2, Lux, Fc, Lumens, cd/m2, cd, W/sr, W/sr/cm2, and more. On board data storage allows continuous monitoring at customer specified sampling rates using the “set it and forget it” datalogging.
Ultraviolet Meter JLT800
The Jelight Company JLT800 radiometers measure everything you need and includes ISO17025 accredited calibration to ensure accuracy. The JLT800 UV meter simplifies measurement by continuously sampling until UV light is detected, then automatically measuring. The device’s large OLED display provides both numerical and graphical representations of the irradiance and dosage. Sampling occurs at 3000 readings per second, allowing belt speeds of up to 77 meters per second, providing a high-resolution profile for both continuous and pulsed light sources.

Filtration Options
The JLT800 spectral filtration was designed to match the photo initiator’s response to UV light which is directly related to its absorption and is very wavelength selective. Most lamps emit broadband UV/IVS/IR, and the lamps output may not change evenly over all wavelengths. The JLT800 filters were designed to monitor changes in output in the areas that effect the absorption, and in turn the effectiveness of the curing. Whether you’re using a low output fluorescent source for sterilization, high intensity mercury or xenon lamps for curing, or narrow band LED’s for photolithography, there is a version of the JLT800 optimized for your needs. The response curves for each filtration option are shown below. Custom designs are also available.
