JSR0302B semi-automatic high vacuum vacuum distillation tester
I. It conforms to SH/T0165-92(2006) 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, automatically record the vacuum temperature, automatically converted to atmospheric temperature with a conversion table.
2. The vacuum degree is measured with a high-precision thin film electronic vacuum gauge, the pressure is displayed digitally, and the residual pressure fluctuation is controlled automatically and manually to achieve a high precision.
3, the use of precision needle adjustment valve to adjust the residual pressure, the residual pressure is accurate and stable, and small fluctuations.
4. 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, so that the operation is fast and convenient without leakage.
5. Adopt the hot air thermostatic system, digital display the temperature of the thermostatic area, and there will be no condensation blocking phenomenon in the branch pipe of the fractional distillation bottle.
6. Simple, convenient and fast operation by touch keyboard.
