Heng Aode new digestion furnace classification and precautions
The digesting furnace adopts well-type electric heating method to make the sample heated in the well type electric heating furnace to obtain better thermal effect, increase the cooking speed, and the harmful gas such as SO2 escaping in the digestive pipe is discharged from the water through the sewage pipe through the suction pump. The sewer is effective in suppressing the escape of harmful gases. The temperature of the furnace is controlled by the intelligent temperature meter and the temperature value is directly displayed. It is easy to use PTFE sealing ring with stainless steel drain cover, no need to replace.

Intelligent digestion furnace
main feature
HYP-320 intelligent digestion furnace was developed by Shanghai Fiber Inspection Instrument Co., Ltd.
The temperature inside the furnace is continuously adjustable, the temperature control precision is high, and the temperature control is stable. The aluminum ingot is heated integrally, the temperature difference is small, and the sample is uniformly digested. The control panel is isolated from the heat dissipation of the furnace body to reduce the influence of the high temperature radiation of the furnace body on the control system. Overheat protection: When the temperature exceeds 500 °C, the heating power is automatically cut off and an alarm is issued. Temperature limit protection: The upper temperature limit can be set. If the actual temperature exceeds the upper limit temperature, the instrument will automatically alarm and cut off the heating power supply to prevent the temperature from rising and the sample is discarded after the temperature control system fails. Automatic 6-stage temperature rise: The temperature and holding time of 6 consecutive stages can be set, and the instrument will automatically complete in order. It is more suitable for samples such as milk that are prone to foam. The hood is vented and the instrument can be placed in a fume hood. Perfect peripheral accessories configuration, convenient for users to scale, display and other work.
Must meet the requirements and maintenance methods
Digestion furnace maintenance and maintenance
1. The heating temperature of the digestion furnace should not exceed 500 °C to prevent damage to the instrument.
2. When the digestive oven is in use, if it is abnormal, it should be turned off in time and reported to the laboratory leader.
3. Do not dismantle the digestion furnace without the presence of a professional maintenance engineer.
4. Filling in the repair and maintenance of the digestion furnace
Measuring range: 0.1mg~200mg nitrogen; Determination quantity: 20pcs/batch.; Speed: 45min/batch; Digestive tube capacity: 250ml; Temperature control range: room temperature~480°C; Temperature control accuracy: ±1°C; Average heating rate :30°C/min; ★Control method: 6-stage non-contact temperature control; ★Exhaust gas sealing material: PTFE; heating method: aluminum alloy integrated heating; ★Safety function: over temperature protection, temperature limit protection; Display: 2.5 inch LCD screen, display the actual temperature and holding time at the same time, and count down, automatically stop heating and alarm after arrival; Power: 220 (V) ± 10% 50 ~ 60HZ; Rated power: 2000W; Dimensions: 405 × 435 × 475 (mm); weight: 27Kg;
20-hole digestion furnace
main feature
HYP-1020 digestion furnace
★The digestion device adopts digital display without contact and open temperature control, and the set temperature and the actual temperature are double display. The heating body is made of aluminum alloy material, which has the advantages of fast heating in the studio and small temperature difference between the furnace holes;
Constant temperature digestion furnace
Digestion furnace introduction
HYP 4-hole constant temperature digestion furnace
According to the principle of classical Kjeldahl method, it is widely used in the digestion of food, food, feed, soil, fertilizer, water, sediment, chemical dairy products, brewing, sugar, medicine, coal, rubber, etc. Accurate, safe and reliable, easy to operate and so on.
8-hole digestion furnace
main feature
HYP-1008 eight-hole digestion furnace
1, ★ using digital display without contact disconnect temperature control, set the temperature and the actual temperature double display, the heating body uses eight ceramic furnace core, double row switch, single row use;
2. The exhaust gas seal is made of PTFE material, which is resistant to acid, alkali and high temperature, ensuring safe operation;
3. In the case of digestion, the harmful gas such as SO2 overflowing in the digestive tract is not required to be ventilated, and all of them pass through the gas hood and are dissolved in the water through the air pump to discharge into the sewer, thereby avoiding environmental pollution of the exhaust gas and ensuring the personal body of the operator. Safety.
Sealed drain pipe.
2) Open the pumping tee water (tap water) so that the pumping tee is in the inhalation state.
3) Turn on the power again, turn on the respective control switches, turn the potentiometer, and adjust the voltage indication 220V to make it quickly digest.
4) In the initial stage of digestion, attention should be paid to prevent the sample from splashing due to rapid heating (the mitigation method can be eliminated)
Turn off the power to 5 minutes after the splash, then turn it on again to continue heating).
5) After the digestion is completed, the digestive and sewage pipes are moved together with the entire trailer to the cooling rack for cooling. Note: During the cooling process, the drain pipe must be kept inhaled (do not put the digestive pipe into the water for cooling)
6) Prevent exhaust gas from escaping.
