Product Details

Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

Temperature display: digital display

Volume: 500ml

 

Product introduction:

ZNHW type electric heating sleeve is made of alkali-free glass fiber as insulating material, Cr2ONi80 alloy wire spring device is installed in it, and a hemispherical heat preservation body shaped by vacuum with aluminum silicate cotton is used for heat preservation. The shell is injection molded at one time, and the upper cover is made of electrostatic plastic spraying process. Due to spherical heating, the heating area of the container can reach more than 60%. The temperature control adopts computer chip as the main control unit, multiple digital filter circuits and fuzzy PID control algorithm. It has the characteristics of high measurement accuracy, small impulse temperature, single-key hydroxyl touch operation, double-screen display, internal and external thermocouple temperature measurement, SCR control output, 160-240V wide voltage power supply, and off-couple protection function. It has the characteristics of fast temperature rise, high temperature, simple operation and durability, is the most ideal instrument for precise temperature control heating test.
