TRN1500 Automatic Nitrogen-in-soil Analyzer

Introduction

TRN1500 Automatic Nitrogen–in-soil Analyzer, independently researched and developed by Beiyu Instruments, is exclusively applied to measure ammoniacal nitrogen, nitrite nitrogen and nitrate nitrogen in soil samples. It is highly intelligent and automatic by integrating extraction and measurement function in design.

Operation mechanism

Put the soil sample into potassium chloride solution, followed by magnetically stirring the blended liquid, then precipitates the soil on the bottom, afterwards, with Gas-Phase Molecular Absorption Spectrometry, the clear liquid on the top of container can be used to measure concentration of ammoniacal nitrogen, nitrite nitrogen and nitrate nitrogen.

Features

1. The measurements of ammoniacal nitrogen, nitrite nitrogen and nitrate nitrogen can be handled at the same time with a single extraction of soil sample, instead of respectively testing based on different items.

2. The extraction efficiency is ensured under accurate control of thermostatic water tank at the temperature of 20°C with an error less than 0.3°C.

3. The soil samples and extracting liquid are evenly blended through automatically magnetic stirring with intelligent velocity-changing control.

4. The contamination to container can be prevented with no need to replace the container in the whole process.

5. The extraction and sedimentation are automatically conducted without mannual operation.

6. Can deal with as many as 30 samples in a single process.

7. The samples with high concentration can be diluted and tested online.

8. Detecting limit:

Ammoniacal nitrogen ....................0.10mg/Kg

Nitrite nitrogen .............................0.10 mg/Kg

Nitrate nitrogen ............................0.20 mg/Kg
