The Nitrogen Analyser NA 1500 is available in 2 different versions and each of these with the variant for the determination of Nitrogen only, Nitrogen-Carbon and Nitrogen-Carbon-Sulphur. These units are as follows:

1.     Nitrogen Analyser Model 1 500-R/AS-200 for Nitrogen Analysis, fitted with:

—      An automatic autosampler AS-200 with one drum of 50 positions (optional up to 4 drums)

—      Combustion and Reduction furnaces with temperature control

—      HWD Control Module 430 coupled to a HWD 45 detector cell with constant temperature or constant voltage operation.

—      Electronic Programmer

—       Pneumatic Control System with pressure controllers and gauges for carrier and   auxiliary gases

—      Electronic peak sensing feature to stop the analytical cycle automatically

—      Built-in Potentiometer electronic Recorder

2.        Nitrogen Analyser Model NA 1500/AS 200 as above but without built-in Recorder.

3.        Nitrogen Analyser Model NA 1 500-R/AS 200 as 1 but for Nitrogen and Carbon      analysis.

4.        Nitrogen Analyser Model NA 1500/AS 200 as 3 but without built-in Recorder.

5.        Nitrogen Analyser Model NA 1500-R/AS 200 as 1 but for Nitrogen, Carbon and Sulphur     analysis.

6.        Nitrogen Analyser Model NA 1500/AS 200 as 5 but without built-in Recorder.
