The Model T101 H2S analyzer uses the proven UV fluorescence principle to measure hydrogen sulfide at levels commonly required for ambient air monitoring.
The Model T101 is equipped with an internally mounted catalytic converter set at 315°C to convert H2S to SO2.  A switching mode alternately measures H2S and SO2 while showing both readings concurrently on the front display.
All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability.  All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.
The Model T101 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ S​oftware. ​
