Overview
DR-16 multifunctional numerical control digestion instrument is a laboratory equipment of JINGQI brand, which is mainly used to realize the chemical analysis digestion function of COD, total phosphorus, total nitrogen and total chromium in various water samples that require heating process. The instrument can place 16 φ 16mm reaction tubes at the same time, and can automatically control the temperature according to the digestion temperature and digestion time set by the user.
Features
The heating speed is fast, and it only takes 15 minutes to rise to the set temperature.
2, high temperature control accuracy.
3, with multi-point error-free Adjustment, to achieve zero error measurement of the set point, completely eliminate the error caused by the non-linearity of the temperature sensor.
4. Adopt effective heat insulation measures to reduce energy consumption.
5. It has a regular reminder function.
6. The instrument has a secondary protection function. When the temperature of the digestion instrument exceeds 185 degrees, the power supply will be automatically cut off to ensure the safety of the digestion process.
7. The standard digestion tube adopts imported Glass, which has the characteristics of not bursting in the state of sudden cooling and sudden heating.
Principle
The instrument heats the sample in the reaction tube through the electric Heating mode, and uses the High Accuracy temperature sensor and Control system to automatically and accurately control the heating process according to the preset digestion temperature and time parameters to meet the digestion requirements in the pretreatment of COD, total phosphorus, total nitrogen, total chromium and other water quality indicators.
Applications
Water quality analysis, environment monitoring, laboratory chemical analysis pretreatment
Standards
The data did not mention specific compliance criteria.
Steps
The information does not provide detailed operation steps.
Notice
The instrument has a secondary protection function that automatically shuts off power when the temperature exceeds 185 ° C. It is still necessary to pay attention to safety when using it.
* Please use the standard imported Glass digestion tube of the instrument to take advantage of its resistance to sudden cooling and sudden heating to prevent tube bursting.
* Note that the Power supply voltage requirement of the instrument is AC220V.
The number of single digestion samples is 16.
* The COD measurement range of the instrument is 5-2000mg/L, and it needs to be measured with a 3cm Colorimetric tank spectrophotometer or titration device.
