Shanghai Jingqi Multifunctional CNC Digester (12 holes)DR-12, Shanghai Jingqi Instrument Co., Ltd. (CAT#: STEM-GLE-2121-YJL)

Shanghai Jingqi Multifunctional CNC Digester (12 holes)DR-12, model DR-12 is manufactured by Shanghai Jingqi Instrument Co., Ltd.
The intelligent multi-parameter digestion instrument can perform digestion pretreatment of samples such as COD, total phosphorus, and total nitrogen, and is suitable for users who measure a large number of samples at a time. At the same time, it also solves the annoyance of many users that the measurement data is inaccurate due to the inconsistency of the digestion process and the inconsistency of the digestion conditions caused by multiple digestions. The instrument can automatically complete the constant temperature timing time, and the time setting is 1-999 minutes. After the constant temperature time is reached, the instrument has an automatic sound alarm function without manual participation. The temperature drift is small and the constant temperature accuracy is high. It adopts PID control, has the characteristics of fast heating speed, small temperature buffer, constant and uniform temperature, etc., and is easy to operate. It is a new product of experimental instrumentation. Compared with the current reflux device for measuring chemical oxygen demand by the potassium dichromate method, it has the advantages of small size, water saving, power saving, time saving, and good constant temperature performance.

PID adjustment constant temperature: PID temperature controller is adopted, the heating speed is fast, the temperature buffer is small, and the temperature is constant and uniform.
Constant temperature automatic timing: automatically calculate the heating time, without manual timing, after the heating time is over, the instrument will automatically maintain the temperature.
Over-temperature automatic power-off: real-time monitoring of the current temperature during the heating process of the instrument, and automatic power-off protection when the temperature exceeds the specified temperature to prevent accidents.
The number and diameter of digestion holes can be customized: the instrument defaults to a 12-hole digestion instrument, and users can customize the number and diameter of digestion holes according to their needs to fully meet customer needs.
