uLUX-LP Illuminance Meter - Low Profile Sensor

This lux meter system includes a low-profile photometric sensor, designed for applications with limited mechanical clearance and an integrated cosine filter for reduced directional sensitivity.

Combined with our highly popular S471 portable photometer, the system provides simple and precise measurements.  The package includes a battery charger and necessary connector cables.

Under the UDT Instruments brand, Gamma Scientific manufactures a broad range of precision photometers, radiometers, colorimeters and photosensors for optical measurement application.
