The Model T102 TRS analyzer uses the proven UV fluorescence principle to measure Total Reduced Sulfur at levels commonly required for ambient air monitoring.

The Model T102 uses a high temperature external converter set at 850°C to allow conversion of H2S, methyl mercaptan, dimethyldisulfide, and methyl-disulfide to SO2 at this temperature with efficiency greater than 98%.  A switching option alternately measures TRS 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 T102 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software. ​
