Description
HAWK 45L Series refrigerant pressure gauges are ideally suited for refrigeration applications such as testing automotive, industrial and residential air conditioning at high quality performance requirement and low cost.
The red temperature equivalent scale provides easy analysis of the refrigeration system. These gauges feature a one piece polycarbonate ring and window. This allows users quick and easy access to internal front adjusting screw on the dial for resetting the pointer.
Typical Applications
- Suitable for use on all freon service applications.
Specifications
OPERATING
Steady: 75%*full scale value
Pulsation: 50%*full scale value
Sudden: 100%*full scale value
The appropriate operating range falls in the middle half of the gauge (25% to 75% of full scale). If you choose the unsuitable range, the fatigue of bourdon tube may be resulted.
TEMPERATURE LIMIT
Ambient: -25 to 60°C.
Media: max 60°C.
TEMPERATURE EFFECT
Accuracy of measurement will be effected by the temperature change. This inaccuracy may as high as ±0.3% for 12°C temperature change.
