UDT Turnkey Light Measurement Systems

We offer a range of commonly paired optical meters and sensors for ease and simplicity in ordering.

All of our Optical Meter systms are designed to be used in a laboratory setting or a field environment. The instruments are microprocessor controlled and have three measurement options; direct analog display; RS-232 interface; or analog voltage output. In addition to our exceptional technical and functional capabilities, Gamma Scientific is ISO/IEC 17025 accredited by NVLAP (NVLAP lab code 200823-0).
