The Kemtrak DCP007-NIR is an advanced dual wavelength NIR photometer designed to accurately measure the concentration of process liquids and gasses with near-infrared (NIR) absorbance between 800 and 1550 nm.
Examples of NIR measurements include moisture (water & trace water), ethanol, methanol, sodium hydroxide, ammonia and continuous fuel identification.
The Kemtrak DCP007-NIR uses a long life high performance NIR LED light source with robust industrial grade fiber optics to deliver a drift and noise-free measurement with very high precision. Automatic compensation for sample turbidity and/or fouling of the optical windows ensures trouble free operation.
Maintenance free measurement cells with sapphire windows have no electronics or moving parts making the unit suitable for hazardous area use.
In-line Fiber Optic Measurement cells
Kemtrak industrial process measurement cells are manufactured from the highest quality materials and are designed to the most demanding specifications to ensure long life and the highest reliability.
Industrial grade fiber optics transmit cold light to the measurement cell and back. The measurement cell contains no electronics, moving parts or sources of heat that would result in condensation on the optical surfaces and they are well suited for hazardous area operation.
