Introduction:
The pressure gauge and remaining-air alarm are integrated into a single unit, providing both cylinder pressure display and an audible alarm when the cylinder reaches its designated limit.
The gauge range is 0–40 MPa, with the operating pressure (27–30 MPa) marked in green and the alarm pressure (5–6 MPa) marked in red. When the cylinder pressure drops to 5 ± 0.5 MPa, the remaining-air alarm emits a continuous 90 dB sound, alerting the user that the air supply is nearly depleted and evacuation is necessary.
For cylinders of 5 L or larger, this remaining air provides approximately 5–8 minutes of breathing time.
Product Advantages
Clear Display:
The pressure gauge provides clear readings and includes night-vision capability, ensuring visibility even during nighttime operations.
Rubber Protective Cover:
A thick rubber layer protects against accidental impacts and damage.
Audible Alarm:
The pressure gauge is linked to an alarm whistle. When cylinder pressure reaches the low-pressure threshold, the gauge emits a mechanical audible alert.
Easy Maintenance:
The shock-resistant design and rugged housing enhance the mechanical pressure gauge’s safety and durability during transport and use.
