The Model T200H combines the proven chemiluminescence principle with a number of innovative features to provide reliable and repeatable NO, NO2, and NOx measurements for extractive type CEM systems.  A high-efficiency stainless steel thermal NO2 converter provides durable and consistent operation under the harshest conditions (other converter options also available).

The T200H may be fitted with an optional, internal paramagnetic O2 sensor or an infrared absorption CO2 sensor, reducing integration and operating costs significantly. 

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 T200H 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.
