Pressure Sensor & Switch
Digital Pressure Gauge
Easy to check pressure reading with digital display
Advantages
Easy to check pressure reading with digital display
Compact body
Body size:30mm width x 30mm height
Dust & water proof: IP65
IP65 can be maintained by operation with a tube inserted to air release port. (Refer to digital catalog)
A power saving mode is adapted. Battery life is about 3 years.
Only one-time pushing the bottom to indicate pressure value. The battery life is expected when pressure value displayed at 5 times a day basis.
Visible indication of battery change time.
Battery level indicator blinks to notify when battery level becomes low.
With a flat-blade screwdriver (1.4mm width), battery can be replaced.

Detailed Safety Instructions
Warning
1.Never use with corrosive or flammable gases or liquids.
2.Do not use in an environment with corrosive or explosive gases as it is not explosion-proof.
Caution
1.When handling, do not drop, strike or subject it to strong shocks. Even if it is not damaged in appearance, it may be damaged inside.
2.If there is a risk of water, dust, etc. entering the main unit through the atmospheric release port, connect a tube, etc. to the atmospheric release port and extend the other end to a safe place (where water, etc. will not be splashed). Be careful not to bend the tube or block the end.
3.When using, connect the air filter immediately before the product.
4.The atmospheric release port must always be open to the atmosphere.
5.Use the specified battery. The use of non-specified batteries may cause malfunction.
6.The batteries must be inserted in the correct direction. Incorrect orientation of the battery may cause the battery to explode or leak, resulting in a malfunction or accident. When not in use for a long time, always remove the batteries and store them separately to prevent leakage.
7.This product cannot be calibrated and should not be used for commercial transactions.
