FAQs: Fire Equipment Gauges

Here are some answers to the most frequently asked questions we receive about our fire equipment gauges.

How Do I Read a Fire Equipment Gauge?

To read a fire equipment gauge, check the position of the gauge indicator needle. It should point to one of three zones:

• Recharge: The red zone on the left is the recharge zone, and it indicates that the equipment should be charged due to low pressure from previous use or leakage.
• Green: Equipment in the center green zone is correctly charged and ready for use.
• Overcharged: The red zone on the right indicates that the equipment is overcharged, or under too much pressure. An overcharged unit can be dangerous, so it’s essential to reduce the pressure or remove the system as soon as possible.

What Pressure Ranges Do Your Gauges Cover?

Our gauges cover pressure ranges from 100 PSI to 350 PSI, including:

• 100 PSI
• 175 PSI
• 195 PSI
• 225 PSI
• 240 PSI
• 350 PSI

Please contact us if you need assistance determining which pressure range is most appropriate for your system.

What Is the Lifespan of a Fire Equipment Gauge?

The lifespan of a fire equipment gauge can last as long as five years when stored and maintained properly. Regular testing and inspection is essential for determining whether a gauge has reached the end of its life or needs to be recalibrated. Check your gauge’s manufacturing guidelines for more specific information.

When Should a Fire Equipment Gauge Be Replaced?

A fire equipment gauge should be replaced every five years. While you may find that your gauges last longer if you choose to repair or recalibrate them, most companies choose to replace them after five years because it is more cost-effective in the long run.

Are These Gauges Weather-Resistant?

While our fire equipment gauges can handle various conditions, they are not completely weather-resistant. Make sure to store your gauge and attached equipment in a temperature-controlled indoor setting to maximize their lifespan.
