I. The structural characteristics
The instrument is mainly composed of two parts: an automatic capillary viscometer and a special cold source for the similar viscosity measurement of grease. The automatic capillary viscometer is designed and manufactured according to the industry standard SH/T0048, and the automatic lifting mechanism is added to make the test more convenient. The refrigeration system uses fully enclosed compressor refrigeration, and the compressor unit uses imported products. It has the characteristics of low noise, low power consumption and large refrigeration capacity. The machine's overheating self-protection device is reliable, so its service life far exceeds that of domestic similar products.
The temperature control system is composed of a temperature control table and a temperature control switch. The temperature control table uses a digital display temperature controller with PID automatic setting function to control the temperature, and the solid state relay is an action component. The control system has high temperature control precision and long-term working performance. And other functions. The appearance of the instrument is beautiful and generous, the structure design is reasonable, the operation is convenient, and the result is accurate.
