 Description

The Model T201 combines a specially configured chemiluminescence analyzer with an external thermal converter (see "Features" tab for external converter photo) to give stable and repeatable NH3 measurements at very low levels.  In addition, the T201 provides simultaneous values for NO, NO2, and NOx concentrations.  The T201 is ideal for trace ammonia monitoring applications in ambient air as well as in clean rooms and make-up air units.  Optional zero and span valves allow automatic, unattended calibration checks.

​The Model T201 achieves its remarka​ble stability by means of an AutoZero valve which measures and corrects for zero noise.  Multiple self-checks are performed continuously to insure maximum up-time while an innovative sample path, plumbed with specially conditioned materials, preserves the NH3 sample and reduces interferents to a minimum. 

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 T201 comes with the Numaview™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.​
