Specifically designed for extractive trace analysis applications, the new SERVOTOUGH LaserExact gas analyzer from Servomex delivers the benefits of Tuneable Diode Laser (TDL) technology within a robust and compact design.

Able to detect a wide range of gases including O2, HCl, HF, NH3, CO, CO2, H2O, H2S, HCN, NO, N2O, CH4 and other hydrocarbons, the LaserExact combines an advanced multipass long path length cell with Servomex’s High Frequency (HF), Frequency Modulated (FM) signal processing.

The result is unsurpassed low ppb detection limits for most gases, making the LaserExact ideal for the measurement of trace gases offline.

Advanced TDL technology delivers a fast response time, stable performance and minimal interference from background gases.

With no moving parts or consumables, the LaserExact minimizes operating costs, while Servomex claims that the stable, drift-free performance reduces the downtime incurred by the calibration requirements of other analyzer technologies.

Designed for easy installation and integration, the LaserExact is immediately ready for operation following the connection of power, sample gas and optional purge gas. With gas concentrations provided as 4-20mA outputs with the option of Ethernet communication, the LaserExact delivers immediate performance that meets ATEX and Class1 Div2 CSA approvals.

The LaserExact is ideal for a wide range of high purity, process and emissions control requirements, with applications including the measurement of H2S and CO2 in natural gas, O2 in flare gas recovery systems, trace O2 in glove box applications, corrosive combustion emission gases, and H2S emissions monitoring.
