Laboratory Installation Conditions for Fully Automatic Kjeldahl Analyzer

I. Requirements for the workbench and working environment

1. Ambient temperature: 10℃-45℃, relative humidity: ≤80%

2. No dust, flammable or explosive gases

3. No direct sunlight

4. Space in front of the workbench: ≥1 meter

II. Power supply requirements for Kjeldahl apparatus

1. Single-phase AC 220V/50Hz ±15% power supply, power line diameter ≥ 2.52mm, two independent power sockets.

2. Sockets must have reliable grounding; neutral wire cannot be used as a substitute for grounding.

III. Tap water requirements

1. Tap water pressure should be between 0.08 and 0.4 MPa. Insufficient pressure will affect the analysis results, while excessive pressure will cause instrument malfunction.

2. The tap should ideally be a quick-connect type or a laboratory-specific tap.

3. The distance between the tap and drain and the instrument should be ≤3 meters.
