PRELAFRO - PRELEVATOR for filter housing

- Control of pressure variation inside classic method sparkling wine bottles.

- Control of 'nitrogen' pressure fed with the nitrogen system.

- Control of the 'vacuum' value in bottles corked with the vacuum system.

- Evaluation of the behaviour of natural or synthetic corks, metal or plastic screw caps and crowns subjected to pressure.

- Evaluation of the behaviour of PET containers under pressure under varying external temperatures. Depending on the model chosen, the instrument quickly and accurately measures the pressure or vacuum existing inside a corked bottle, previously filled with liquid.

The measurement is also made possible with a stainless steel needle that is suitably shaped and pierced. The needle, inserted manually through the bottle closure cap, has the function of transferring the pressure or vacuum values to the pointer of the glycerine oil bath type stainless steel pressure gauge. The 60 mm diameter pressure gauge placed in the optimum position will allow easy reading of the values.
