Process Instruments


AMETEK offers on-line process analyzers for the accurate determination of the trace moisture content of gases. Analysis ranges and accuracy vary by model from as high as 2500 parts per million by volume down to <1 part per billion by volume. In addition, AMETEK provides a line of products based on tunable diode laser technology.

Tunable Diode Laser Instrumentation

The Model 5100 Tunable Diode Laser Absorption Spectroscopy (TDLAS) gas analyzers use an extractive system. Tunable Diode Laser Absorption Spectroscopy is a highly selective, sensitive and versatile technique for measuring trace species in gas analysis. The diode laser source emits in the NIR region and is ideal for optical spectroscopy because of its narrow line width, tunability, stability, compactness and ability to operate at room temperature.

Currently, there are two models available. Model 5100 is a single laser, single gas analyte system and is ideal for sample dewpoint temperatures up to 55ºC. Model 5100HD is a dual laser, multiple gas analyte system and is ideal for sample dew point temperatures up to 100ºC. A high temperature version up to 150ºC is also available. Both 5100 and 5100HD can measure moisture, methane, hydrogen sulfide, carbon dioxide and oxygen.

Model 5100 and 5100HD have a built in reference cell for on-line verification and all three models have laser line lock function, a feature that is unique to AMETEK 5100 series analyzers. Model 5100 HD can be configured for dual cells, dual stream applications.

Model 5100 series analyzers are comprised of fully enclosed optics, electronics, sample handling and built-in verification. The Model 5100 and 5100HD units are designed for outdoor installation and are certified for worldwide hazardous area locations.
