How does the 5-psi buffer zone work?

The buffer zone prevents the heater relay from rapidly cycling. If your target pressure is 900 psi, the heater won't turn on until the pressure drops below 895 psi, and it won't turn off until it reaches 900 psi. This provides a more stable pressure reading and prevents unnecessary wear on the relay.

What is included with this gauge and controller?

This kit includes the 2-1/16 inch gauge with integrated controller and the necessary components to monitor and manage your nitrous bottle pressure. Please refer to the manufacturer's packaging for a complete list of included hardware.

Is this gauge compatible with all nitrous bottle heaters?

This Nitrous Express gauge and controller is designed to work with NX bottle heaters. Compatibility with other brands may vary, so it's best to confirm with the manufacturer or consult your bottle heater's specifications.

About this part

Product Details

When you're running nitrous, keeping your bottle pressure steady is crucial for a consistent run. This Nitrous Express gauge and controller combo is designed to help you achieve just that. It monitors your nitrous bottle pressure and automatically activates your bottle heater to keep it within your desired range, all without you having to leave the driver's seat.

The system features a 5-psi buffer zone. This means it won't rapidly cycle the heater relay on and off if the pressure fluctuates slightly around your target. This well-built unit helps ensure that your nitrous system performs predictably every time you hit the button, making for a more reliable and effective nitrous injection.
