Ⅲ. Features
A. Features of main frame
1. Continuous barrier-free work to ensure the integrity of the
test.
2. Easy to operate and maintain for branch stations are independent
from each other.
3. Main components are imported from Europe or America, which are
stable and reliable.
4. On the basis of the meters, the instrument is also equipped with
brand laptop or desktop which is connected with the meters by
serial ports.
5. Pressure-time curve and Pressure-temperature curve can be drawn.
6. Pressure value can be inquired real-time.
7. Automatic regulate the pressure on the computer.
8. Test reports can be printed.
9. Computer can stop working at any time, because the meters of the
main frame can still work.
10. The PC is installed with the latest version of hydrostatic
pressure test software in Chinese or English which are free to
upgrade for life long.
B. Features of constant-temperature tank
Constant-temperature tank is composed of the tank body, imported
circulation pump, heating unit and temperature keeping system.
1. The body is composed of structural frame, bottom, 304# stainless
steel internal bladder, and stainless steel or aluminum alloy outer
covering.
2. Thick heat insulation of rigid polyurethane foam ensures the
constant temperature and energy saving performance.
3. The cover of the constant temperature tank can be equipped with
automatic lifting and closing device, which is reliable and
convenient.
C. End caps:
1. Include bolt, O ring ,vent valve etc all assembled complete.
2. Fixture structure:
Half round pot form,easy fit out , no leakage, convenient
operation.
D. Refrigeration system
Temperature range: 10~40°C
Power supply:220V single phase 2.2KW
