DF-745 SGMax

Tunable diode laser (TDL) sensor-based trace moisture analyser, designed for measuring diverse gas mixtures in specialty gas blending applications



Sensing Technology


Using intelligent integrated software, this device includes 
a database of 17 standard background gases – with blends of up to 8 gases – providing an adaptable solution for diverse application needs; 30 custom gas mixtures can be predefined directly via the front panel interface. A robust hardware / software design enables the SGMax to be moved easily from port to port, virtually eliminating dry down times often associated with these applications.

Servomex’s leading-edge TDL technology has been engineered to deliver a broad measurement range of 0-100ppm, with an incredible low 5ppb LDL – the lowest available without using a pump. This device is also highly affordable over product life, through the use of ultra- stable, zero drift sensing technology that helps to extend calibration periods and reduce ongoing maintenance needs.
