- Model CMS-4000 - Continuous Monitoring System


The CMS-4000 is a simple, reliable tool to measure petroleum hydrocarbons in water. With no moving parts and corrosion protected components, the system can be utilized in many different applications.

The CMS-4000 detects the presence of petroleum hydrocarbons in water using the patented Fiber Optic Chemical Sensor (FOCS®). The FOCS probe takes advantage of the interaction between the light traveling through a fiber and a water solution containing petroleum hydrocarbons. As the concentration of hydrocarbons increases, the light scattered from the proprietary probe fiber increases in a quantitative relationship. The probe output is monitored by a controller that has 0-5 volt or 4-20 mA output and remote access capability. The system can monitor up to four (4) probes.

The probe is intrinsically safe and designed to be remotely mounted in hazardous locations.
