HF control circuit: It is used for automatic detection of the electromagnetic valve, the elevation or descent of cylinder and the performance of HF unit.
Automatic overtime/overflow alarming system enables the HF furnace to work under normal condition.
The optional current/voltage/power regulator for furnace temperature control: It is applicable to samples of various materials.
Analytical gas path system
Gas path: The high precision flow controller ensures the stability of gas flow as well the gas intake system (such as electromagnetic valves, unions, cylinder hoists) for automatic leakage detection.
Dual standard correction for solid and gas
De-dusting unit: The combustion head self-cleaning device effective for reducing the influence of dust for the result of analysis; ash removing system for the inlet.
0.4 μm submicron metal filter secures thorough separation of dust from gas and can be used for a long time with no need of the ultrasonic cleaner.
Input/Output System

software.
Analysis channel: Providing channel management features, the carbon and sulfur channels are free to increase, delete and edit, no limit. Preset the interface of low-carbon and sulfur, Can realize the software automatically change
Analysis function: Analysis of the dynamic data, sampling every 20 times, improving the analysis sensitivity and analysis accuracy, providing sample management features, it can edit the sample name and logo, also can increase and delete samples, the software provides a user management system, the administrator setting different user permissions.
Display function: The Carbon sulfur has a curve respectively,
Data processing function: Adopt ACCESS data pool store the analysis results, can store all data and curve;
Query the analysis results optionally, query according to the time, sample name, logo and operator.
Provide some function as data storage, blank deduction, setting parameter, choosing channel, statistics, and curve Compare etc.
In the software can create the work curve of carbon and sulfur, realizing the curve fitting.
Printing function: Print mode is diversification, Provide two print modes of laboratory and testing, also can design printing formats
self-diagnose function: System diagnosis function,can test furnace head and the gas chamber sealing by the software.
