Highlights:

1. No disassemble or cooling required, easy to replace the combustion crucible.

For the elemental analyzers, the combustion residues will remain in the combustion crucible, after some quantity of tests (about100 tests), it needs to be replaced. For other brands, it is complex and time wasting, operators need to wait for the furnace cooling down and disassemble the analyzer, then replace the crucible manually. For Sundy SDCHN335, operators only need to click on the software, the crucible to be replaced will be presented out from the combustion furnace to the crucible replacing door by the mechanism automatically. Once the crucible is replaced, tests can be conducted immediately.

2. High automation

Up to 34 samples can be loaded and after that, operator can be freed for other tasks. The analyzer will finish the whole test process automatically.

3. Ultra-low drift infrared cell and thermal conductivity cell

With high-performance infrared light supply and superior optical glass as well as pure gold infrared path and precise thermostatic control, the drift of the infrared cell and thermal conductivity cell have been optimized which is developed and designed by Sundy.

4. Improved test precision

Samples are carried into the combustion furnace by oxygen blow, to make sure all the gases obtained by combustion are collected into the gas chamber to improve the test precision.

5. Low operation cost

Oxygen and nitrogen with purity of 99.5% can meet the test requirement.

6. Shortened preheating time

Preheating time is less than 2.5 hours.

7. Convenient to replace the reagent furnace

Separate design of combustion furnace and reagent furnace makes the replacement of the reagent easy and convenient.

8. Simple to operate

Easy to use Windows-based operating software, after weighing and loading the samples, only mouse clicks required.

9. Easy to handle

Easy data handling, real time data can be transmitted by internal network.

With CAN bus interface, several elemental analyzers can be controlled by a single PC.

Connect with balance and network by standard interface RS232.
