SKD-800 nitrogen analyzer

SKD-800 Kjeldahl nitrogen analyzer features: $n $n * SKD-800 nitrogen analyzer design requirements - protect the tested sample from damage. $n $n * Brand new one click start, LCD touch screen, minimalist operation, one step into the experimental program! During the distillation process of the instrument, unexpected situations such as stopping the cooling water, lack of alkali, acid, and distilled water may cause the instrument to alarm. Wait for recovery and record the condition of the instrument. After receiving a response, the instrument will automatically calculate and continue distillation. The instrument casing is made of ABS engineering plastic mold to prevent corrosion by sulfuric acid. $n $n * uses materials that are resistant to high temperatures and acid and alkali, ensuring the internal corrosion, leakage, and sealing of the instrument. The internal pipelines are guaranteed to be non replaceable for three years.

Design concept of SKD-800 nitrogen analyzer:

Protect the safety of the tested sample: The sample is protected from damage in the absence of any liquid or cooling water.

Ensure the correctness of sample distillation: a reasonable and adjustable distillation method; Reasonable segmentation and liquid addition method.

SKD-800 nitrogen analyzer features:

*Design requirements for SKD-800 nitrogen analyzer - protect the tested sample from damage.

*Newly opened one click start, LCD touch screen, minimalist operation, one step into the experimental program!

*During the distillation process of the instrument, if there are unexpected situations such as stopping the cooling water, lack of alkali, acid, or distilled water, the instrument will sound an alarm. Wait for recovery and record the condition of the instrument. After a response, the instrument will automatically calculate and continue distillation.

*The instrument casing is molded with ABS engineering plastic mold to prevent corrosion by sulfuric acid.

*Using materials that are resistant to high temperatures and acid and alkali, ensuring the internal corrosion, leakage, and sealing of the instrument, and ensuring that the internal pipelines do not need to be replaced for three years.

*Eliminating the phenomenon of backflow.

*Real time temperature detection for distillation cups; If the temperature inside the collection bottle is too high, the instrument will stop distillation. After the temperature drops, it will automatically continue distillation for the remaining time.

*Manual and automatic dual modes can be switched freely, and the entire testing process is tracked and displayed in real-time.

*Data storage and editing methods: automatic preheating, cleaning, adding acid and alkali, adding diluent, storing 999 programs;

*Distillation power adjustable at 1500W; Ensure good recovery rate of low solubility samples.

*Equipped with automatic addition of diluent; Automatic alkali addition; Automatically add boric acid. The distillation power is adjustable to ensure the recovery rate of high and low concentration samples during distillation, and both have liquid level detection.

Equipped with powerful security protection functions:

1. Distilled water, diluent, acid, and alkali liquid level protection (real-time monitoring), and the liquid addition system adopts a constant pressure pump to ensure consistency of liquid addition.

2. Cooling water interruption, insufficient cooling water, sample protection;

3. Real time monitoring of collected liquid temperature;

4. The distiller adopts dual level control (dual safety) to prevent dry burning.

5. Real time detection and prompt function for whether the protective door is closed;

6. Intermittent alkali addition ensures that the acid-base reaction is under control and prevents splashing during sample distillation.

7. Adopting a large screen LCD display, the circuit, water circuit, and air circuit are independent of each other (with an external reagent tank).

8. During the distillation process, alkali can be manually added at any time to ensure accurate sample data.
