tfs tunable filter spectrometer multi-compound trace gas monitor

Overview

The MultiGas™ TFS™ Monitor is an online, multi-compound, trace gas monitoring system in a stand-alone 19-inch rack enclosure. It uses an innovative tunable filter spectroscopy technology enabling high selectivity and stability measurement. Low detection limit (sub-ppm levels for most gases) is achieved through the use of high throughput optics coupled with a long-path gas cell and a high sensitivity detector.

A single analyzer measuring multiple compounds
High analytical performance – low detection limits, high stability, linearity over wide ranges
Complete, integration-ready system reduces complexity and ensures fast install time
Permanent calibration reduces the need for costly calibration gas cylinders
Low cost of ownership, easy to install and maintain
Continuous measurement for rapid detection of changes in effluent composition

Features

All-optical TFS Monitor

The all-optical MultiGas TFS Monitor provides an alternative to the traditional analyzer technologies for gas concentration measurement.

Permanently Calibrated

The analyzer calibration is permanent, reducing the need for costly reference gas mixtures. The calibration stability is guaranteed through the use of an advanced spectral processing algorithm that compensates for baseline variations.
