NHS Ammonia Analyser System





NHS Ammonia Analyser System

The IAG NHS is a 191C heated diode laser ammonia detection system.

This very compact and light system can be used in a wide variety of applications.

2 sample gas inlets, built in gas inlet pressure regulator, heated sample gas filter, integrated purge function, span gas connection and any kind of communication option you might eventually like are basic technical features.

Setup and operation are kept as simple as possible without sparing an operation software with all functions the advanced user would expect, including alarm parameterisation, calibration and linearization functions as well as open communication settings.

Operation can be done via pushbutton on the device, via the operation software with network connection to the device or via communication interfaces such as AK, RS232, Modbus or Profibus. Another important issue is response times. IAG has been developing heated prefilters since 1998 and has worked ever since to create sampling modules and measuring systems with minimum internal volume, optimised gas flow, uniform heating and special surface treatment.

Therefore this system has the ability of realising very short response times. Another important thing to mention is the maintenance friendliness of our products. Annual maintenance can be easily done by the user and wear parts are available for very reasonable prices.
