infrared ATR probes are highly-selective and highly-accurate inline
Multi-parameter ATR Sensors are a step ahead of alternative methods.
VitalSensors producs do not extrapolate concentrations using pressure, density
or sound velocity. The optical ATR method is not affected by solids,
variable pressure, viscosity, turbidity or dark-colored fluids. Therefore, VitalSensors offers Quality
personnel with the highest level of accuracy.

VS-3000E ATR Optical Sensors
VS-3000E sensor probes are compact,
industrial-grade, mid-infrared spectrometers.
VS-3000E sensors measure the contents of
liquids directly and with great precision. A common physics
package accommodates various narrow-band-pass interference filters
for each detector element and isolates these specific infrared
wavelengths for the component being measured. A highly accurate thermistor to measure
temperature and an optical element that creates infrared absorption
by means of ATR or Trans-ATR™ are key components of the
generation of VitalSensors products measure up to 9 process
variables using only 1 infrared probe / process connection.
spectroscopy works because chemical bonds have specific frequencies
which vibrate at corresponding energy levels. The resonant
frequencies are determined by the shape of the molecular potential
energy surfaces, the masses of the atoms and eventually, by the
associated vibronic coupling. In order to measure a sample,
infrared light is passed through the sample, and the amount of energy
absorbed by the substances chemical bonds is recorded. Over the
years, detailed absorption tables of bonds in organic molecules have
been developed and are used to identify and measure samples very
precisely. VitalSensors products use the Beer-Lambert Law which
is central to molecular spectroscopy. Beer-Lambert allows for
determination of the Molar Absorptivity, a characteristic which
indicates how much light of a particular wavelength a sample absorbs.
infrared spectroscopy is widely used in laboratories and for quality
control. Most of these instruments are extremely expensive.
One of VitalSensors core company goals is providing affordable in-line,
infrared, instruments affordable for large-scale deployment in process
VS-3000E Sensor Systems are solid state devices which contain no moving parts.
Therefore there are no recurring maintenance or ancillary hardware
instrument is designed to operate 24x7. Mean time to failure is over 50,000 hours.
