Request InfoInternational Light Technologies, Gilway & International Light Divs.PEABODY, Mass., July 9, 2012 — International Light Technologies has enhanced its ILT1400 handheld portable radiometer/photometer. Used in the field or in the research lab, it has a 7-decade measurement range, autoranging and NIST-traceable accuracy. The most significant updates are the addition of a USB port that now permits data logging of measurements, the replacement of the original keypad with a redesigned membrane one that includes a backlit display, and the replacement of alkaline batteries with rechargeable ones. The ILT1400 also features a large selection of application-specific “smart”...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/24/2022Ethylene Oxide Monitoring SystemThe Ambient Air Monitoring System for Ethylene Oxide (EtO) has been announced by Picarro Inc., providing a continuous, automated solution for community monitoring stations and industrial fencelines....Photonics.com 4/12/2024Machine Vision TunnelThe 380 Modular Vision Tunnel from Cognex is an automated scanning solution for logistics operations.
