KDN-19H Automatic Nitrogen Analyzer, 440×440×735mm, Shanghai XianJian Instrument Co., Ltd. (CAT#: STEM-AIAE-3353-LGZ)

KDN-19H nitrogen analyzer is a brand-new product that integrates 30 years of experience in the instrument industry of Shanghai XianJian Instrument Co., Ltd. The product has been comprehensively upgraded in many aspects of performance. The sample is automatically discharged, and new technologies such as four-fold protection of the evaporation furnace independently developed by Fiber Inspection, automatic sample discharge, automatic lifting of the receiving bottle bracket, and condensed water monitoring are integrated, and the parameters are upgraded. The rear instrument is safer, more stable and more reliable, and the work efficiency is 25% higher than that of the previous generation. Through the strict requirements and continuous improvement of the quality and process of each component of the product through fiber inspection, while being durable, you can always feel the excellent experience brought by KDN-19H in daily use.

The new operating system is easy to use and powerful. With the 7-inch high-definition color touch screen, the experimental process is controlled in real time, making the entire experimental process simple.
Fully automatic lifting and lowering of the receiving bottle bracket, adding dilution water, adding boric acid, distillation, adding alkali after a delay, flushing the receiving tube, automatic emptying of the digestive tube, free cleaning function, fault self-checking and other functions (during operation, the alkali can be added, more human).
Added double protection procedures for water shortage in the evaporation furnace and over-temperature protection to prevent dry burning due to lack of water and improve the safety factor.
Increase the overpressure and pressure relief protection of the evaporation furnace to prevent the explosion of the bottle caused by the excessive pressure of the evaporation furnace caused by the failure of the solenoid valve, and improve the safety factor of use.
When the sample detection is over, the digestion waste liquid is automatically and quickly discharged, and the cleaning time can be freely set.
The internal components of the instrument are fully upgraded, which is sturdy and durable.
After the parameter upgrade, the work efficiency is increased by 25% compared with the previous generation.
A new generation of automatic lifting system for receiving bottle holder, smooth movement process, low noise, and flushing the receiving tube, making the human-computer interaction more friendly and closer to the national standard operation.
Water-saving function design, through program control, condensed water is turned on synchronously during sample detection, and automatically turned off after the detection, advocating a new concept of energy saving, emission reduction and environmental protection.
Condensed water monitoring, when the condensed water speed is low, it will alarm and stop working to protect the instrument and ensure reliable experimental results.
The splash-proof tube is formed of special high-performance acid and alkali-resistant heat-resistant plastic, which has good sealing performance, stronger alkali resistance than glass, and prolongs the service life.
Prevent the sucking function of the receiving liquid and digestive juice to ensure the quality of the test and the safety of use.
