KND-1 Automatic Kjeldahl Nitrogen AnalyzerDetailed product description：

The KND-1 Kjeldahl automatic nitrogen analyzer uses the internationally recognized Kjeldahl nitrogen determination method to automatically determine nitrogen in nitrogen-containing samples. Fully intelligent software design allows experimenters to easily complete the distillation of samples in just a few minutes. The comprehensive security system fully embodies the humanized wisdom of Leici. Automatic quantitative addition of reagents, unmanned throughout the entire process, and intelligent detection of various states. The distillation and condensation automatic cleaning system further improves the measurement accuracy. Leici provides the instrument with multiple language versions, a Chinese dialogue interface, and rich display information, making it easy for users to master the use of the instrument.

Performance characteristics:
Switching between automatic and manual modes to add diluent to meet experimental needs
Adopting automatic alkali addition system and precise metering system to achieve precise control of alkali addition amount
Fully automatic boric acid quantitative injection control system
Set the distillation time arbitrarily, and the distillation will automatically sound an alarm upon completion
The automatic cleaning control system can achieve automatic cleaning of the distiller and higher measurement accuracy
A complete safety protection system that can measure and protect against overheating and overpressure in distillers and pipelines
Intelligent design of facilities around nitrogen pipes, including safety protection design and out of place notification function
Intelligent cooling water control system can achieve control and detection of cooling water
Emergency stop operation function to cope with unexpected needs
Intelligent design of fault automatic detection and sound light alarm system
