Custom Sensors & Technology

Custom Sensors & Technology design and manufacture process photometric and oxygen monitoring systems. Additionally we provide over 60 different applications to a broad range of industries. Custom Sensors & Technology provide solutions for customers who were in search of monitoring solutions in a wide variety of industries. CST started by supplying sample handling systems then providing oxygen sensors. The company expanded it`s horizons to absorbance (color) monitors and received its first patent. From there CST branched out into the UV and NIR regions of the spectrum and began to develop a line of photometric transmitters as well as process accessories to develop customer specific sample systems and provide sensor integration into any industries’ process. Since the inception of the company CST has applied for and holds 8 patents.
