Method of using soil sample digestion instrument

1、 Jingda InstrumentJD-U24Product features of soil sample digestion analyzer:

1Efficient and powerful digestion ability Strong sample processing capability,zMultiple simultaneous processing60A sample with high efficiency and large sample processing capacity.

2Accurate temperature control and uniform digestion The product adopts an isostatic pressing high-purity ultrafine graphite heating module for heating, which has good consistency and repeatability in digestion, fast heating speed, and high temperature control accuracy.

3Designed for corrosion resistance and durability, with a left and right split design, the controller and digestion unit are separated to protect electronic components from corrosion;The double-layer insulation design between the heating part and the control part effectively protects the control part from high temperature damage, thereby extending the service life of the instrument. The workbench is coated with Teflon for anti-corrosion treatment, and the whole machine is treated with anti-corrosion coating to ensure the normal operation of the instrument in acidic environments.

2、 Product Usage:

Jingda InstrumentJD-U24Soil sample digestion instrument is a new generation of inorganic sample pretreatment equipment, which applies new digestion technology and has the advantages of strong sample processing capability, fast heating, intelligent program control, temperature balance, etc. In addition, the controllable temperature electric digestion instrument has a significant energy-saving effect, and the amount of acid used for digestion is greatly reduced compared to traditional methods, greatly reducing pollution during the digestion process. It can also be used for pre-treatment of microwave digestion and acid treatment, including atomic absorption, atomic fluorescenceICP-AESIdeal matching products for analytical instruments.

3、 Application areas:

1In the field of environmental analysis Soil and sediment testing, water quality testing field

2In the field of food and medicine Pharmaceutical, food and beverage, feed and fertilizer fields

3In the field of factory and mine analysis Mining, raw material testing, and product quality inspection fields

1. User parameter setting: Long press in standard stateSETKey, upper display on LCD screenLK, adjustLK=8Click on itSETThe key can enter.

2. Temperature control parameter setting: Long press in standard stateSETKey, upper display on LCD screenLK, adjustLK=18Click on itSETThe key can enter the temperature setting.

3. Temperature cooling control parameter setting: Long press and hold in standard stateSETIf the key is pressed, the upper display on the LCD screen will showLK, adjustLK168Click on itSETThe key can enter the temperature cooling parameter setting.

4. Reservation power on setting: Long press in standard stateSETIf the key is pressed, the upper display on the LCD screen will showLK, adjustLK0Click on itSETPress the key to enter the reserved startup parameter settings.

Further explanation on the operation:

1Set value modification: Press the function key, and the corresponding time and temperature setting area will flash. Modify the set temperature and time in sequence.

2Self setting function (fixed value control requires timing control)Stset as0）If the temperature control is not ideal, please start the temperature self-tuning at the standard state and long press the shift button5Seconds, start temperature self-tuning, the indicator light flashes at this time, and the indicator light stays on after self-tuning is completed, indicating a new set ofPIDTemperature control parameters; The temperature control effect has been greatly improved. To cancel the temperature self-tuning, long press the shift button5Just a second.

3Timer function: If a timer is set, the instrument will stop running when the timer is set, and the increase and decrease keys will be pressed simultaneously5In seconds, the instrument restarts and runs again.

4: Allow devicesZHigh temperature protection: When the temperature exceeds the maximum allowable temperature of the equipmentAPWhen the temperature exceeds the allowed limit, turn off the heatingZhigh temperature2After minutes, the buzzer kept beeping. If the auxiliary function is selected as1Then the auxiliary function relay output is turned on.

5Multi segment programming settings: Press the function key and refer to the corresponding display image（1）Number of cycles,(2)Number of program segments, （8）Set temperature and（4）The time period area flashes separately, and the settings are modified in sequence. If the first period of time is set as0Only run the first segment, for multi segment programs, the subsequent segments will be hidden and have no effect, and so on.

6Set value modification: Press the function key, and the corresponding time and temperature setting area will flash. Modify the set temperature and time in sequence. The first period of time is set as0Only run the first segment without any timing. For multi segment programs, if only three segments are run, set the time for the fourth segment as0Just do it, and so on; fixed value
