Product Description

BIOBASE 0-240mgN measurement range Fully Automatic Kjeldahl Nitrogen Analyzer 

Product description:
1. Dual mode of automatic calibration method which instrument eliminates errors and traditional direct input method.
2. Automatic calibration method which instrument eliminates errors: this method eliminates system errors which are caused by the difference between the exterior calibration of instrument and the instrument titration (calibration) and makes the system precision higher.

Safety protection system:
1. Digestion tube vacant protection: the system will not heat up if the digestion tube isn't put in.
2. Safety door vacant protection: if the safety door isn't pull down, the system will not heat up.
3. Automatic water-replenishing function of steam cylinder: when the steam generator has no water or its water level not high enough, the system will replenish water automatically to avoid burning without water.
4. Steam overpressure protection: when the pressure of steam generator system is too high because of the blocking and breakdown of steam pipeline or abnormal steam pipeline, the system will automatically stop running and give an alarm
5. Leakage protection: when system has leakage of electricity or the operator gets an electic shock by accident, the system will switch off the electricity and cut off power supply to make sure the operator is safe.
