JSR0302 high vacuum vacuum distillation tester

I. Comply with SH/T0165 standard

Ii. Main technical parameters

True air pump: pumping rate 2 l/s

Display mode: digital display

Pressure display: digital film vacuum gauge, pressure automatic balance

Residual pressure: 2 ±0.25mmHg

Power supply: AC220V± 10% 50HZ

Iii. Performance and Characteristics:

1. The vacuum degree is measured by high-precision thin film electronic vacuum gauge, the pressure is displayed digitally, and the residual pressure fluctuation is controlled automatically and manually to achieve high precision.

2, the use of precision needle adjustment valve to adjust the residual pressure, the residual pressure is accurate and stable, and the fluctuation is small.

3. The main machine and vacuum pump are divided into two parts to eliminate the vibration. Vacuum quick connectors in accordance with national standards are used between the vacuum pressure gauge and buffer tank and between the main machine and vacuum pump.

4. Adopt the hot air thermostatic system and digital display the temperature of the thermostatic area. There will be no condensation and obstruction at the branch pipe of the fractionator.
