Product Description

The HS**8L electronic pressure comparator is an excellent pressure source designed for comparative calibration purposes. Depending on servo valve control, pressure is quickly stabilized and remains unchanged after stabilizing. With an external air source, it easily generates pressure up to **0bar. An F-adjust valve provides precise adjustment of pressure, and the minimum adjustable pressure value is 1kPa. In addition, the gauge comparator ensures fast pressure generation. Only 5 seconds are needed from zero to full range.

Pressure Comparator Features

1. A transparent oil cup is convenient for observation of working medium and it can be easily removed for cleaning.

2. 5 pressure ports with standard M*0*1.5 quick connectors allow simultaneous connection of 4 pressure gauges under test, making calibration more efficient and time saving.

3. It is quite easy to operate. Only one finger is needed to generate pressure from zero to full range.

4. Air circuit features rugged and reinforced construction. This leads to high sealing performance and more stable pressure generation.

5. Unique priming function widens the calibration range and successfully handles the difficulties in calibration of several gauges.

Applications

Huaxin's HS**8L Electronic Pressure Comparator Similar comparators from our competitors

Pressure generation system and sealing stability 1) With the most effort saving pressure generation system in the industry;

2) External air source;

3) Time for pressure generation to *0mPa s less than *0s; Time for stable pressure is less than 5s;

4) High stability;

5) Superior servo valve for pressure control;

6) Strict pressure tight test and aging test before delivery

Stand-alone priming pump and manual pressure adjustment;

Not easy to operate and not accurate pressure control

Filtration system 1) Multi-function oil cup that features one-piece design with the shut-off valve;

2) Oil cup comes with filtration system, making it easier to clean and change;

3) No liquid level difference No such function

Priming system Multi-angle rotation priming pump can be operated at different angles according to personal habits No such function

Safety 1) External air compressor with pressure control system; 0.6mPa air pressure from the air source is enough to generate pressure to *0mPa;

2) Over pressure protection function for the gauges

Independent handpump for system priming likely results in damage of gauges; this is dangerous

Airtight performance 1)Quick connection of air source ensures excellent airtight performance combined with high pressure control accuracy (hydraulic pressure
