ST115BS Semi-automatic nitrogen analyzer
ST115B Semi-automatic Kjeldahl nitrogen analyzer uses the internationally recognized Kjeldahl nitrogen determination method to automatically determine nitrogen-containing samples, allowing experimenters to easily complete sample distillation within a few minutes; Automatic quantitative addition of required reagents; Intelligent detection of various states, automatic distillation, and condensation; The instrument has a user-friendly interface and rich display information, making it easy for users to master the use of the instrument.
Performance characteristics:
● Switch between manual and automatic modes, and automatically add alkaline solution and boric acid absorption solution in a quantitative manner.
● Can store 10 sets of experimental programs to meet the different needs of users.
● Add diluent in two ways, automatic and manual, to meet the needs of various experimental conditions
● Distillation time can be set arbitrarily, and automatic alarm will be triggered after distillation ends
● A perfect safety protection system that can measure and protect the temperature and pressure of the still and pipelines
● Intelligent Design of Fault Automatic Detection and Sound and Light Alarm System
● Widely using corrosion-resistant materials such as stainless steel can extend the service life of instruments
