Calibrated Light Meters

The ILT1000 from International Light is a self-contained light meter and sensor in a low profile housing. The versatile UV, VIS and IR datalogging optometer is capable of measuring 8 decades of light intensity (ie nW/cm2w- W/cm2) and providing direct readout in many calibrated units of readout including W, W/cm², J/cm2, Lux, lux*s, Fc, Lumens, cd/m², cd, W/sr, W/sr/cm² and more. The 4-20 mA output can be connected to a PLC for process control. An extensive API is provide for custom programming.

The ILT2400 from International Light is a portable easy to use light meter loaded with features and applications all accessible on a large full colour touch screen display. Simple touch screen operation allows users to view numerical and graphical output of light measurements in lux, fc, W/cm2, W, candela as well and the total integrated dose/exposure in joules, J/cm2, Lux*seconds and more. Sensors are available off the shelf covering the UV range to the IR range. All systems are calibrated in our NIST calibration lab and include ISO/IEC 17025:2017 accreditation.

The ILT2500 CW and Pulsed/Flash portable light measurement system from International Light combines all the excellent features of the ILT2400 light meter, the broader measurement range of a research radiometer, and the pulsed light profiling similar to an oscilloscope.

The ILT5000 from International Light is the replacement for the ILT1700 light meter. Its smaller size makes it at home in the lab and in the field. Advancements include rapid optical measurements for graphically profiling the output of intense pulse light sources, a broader measurement range, Datalight III for PC and Mac, an iPhone app, plus built-in wireless, data storage, and rechargeable batteries.
