Helios Vacuum Oven Gauge/PSI Gauge 60mm - 30 Hg 0 - PSI Replacement

A spare or replacement 60mm Vacuum/PSI Gauge with a range of up to 30 inHg typically has these key features:

Design & Size

• Diameter: 60mm (about 2.36 inches), which makes it compact yet easy to read.
• Face Design: Most gauges have a sleek and clear face with a black background or white face, making the readings easy to see, even in low light. The scale will be marked with the vacuum range (usually from 0 to 30 inHg) and may also have PSI (pounds per square inch) markings.
• Needle: A sharp, clear pointer that indicates current pressure or vacuum readings. The needle typically moves smoothly across the scale.

Range & Measurement

• Pressure Range: Typically, the vacuum side of the gauge will measure from 0 to 30 inches of mercury (inHg), useful for applications where vacuum conditions need to be monitored (such as in engines, HVAC, or automotive systems).
• PSI Range: Some models also measure PSI, useful for both vacuum and positive pressure systems. In such cases, the scale will also feature readings from 0 to 30 psi or beyond.

Materials

• Housing: Often made of high-quality plastic or metal (stainless steel), providing durability and resistance to harsh environments.
• Lens: A glass or clear plastic lens, designed to protect the dial and ensure readability over time. Some versions may have a smoked or tinted lens for glare reduction.
• Backlighting: Many models include LED backlighting in white, blue, or amber to make the gauge easy to read in low-light or nighttime conditions.

Accuracy & Reliability

• Precision: The gauge is designed to provide highly accurate readings, often with a mechanical dial and calibrated for precise measurement.
• Vibration Resistance: Some models use a glycerin-filled housing to dampen vibrations, which helps maintain accurate readings in dynamic environments like cars or industrial machinery.

Applications

• Automotive: Used for monitoring engine vacuum or boost pressure, ensuring optimal engine performance.
• HVAC: Commonly used to measure vacuum levels in refrigerant systems, indicating whether the system is properly evacuated.
• Industrial Use: Used for monitoring pressures in pumps, compressors, and other machinery.

If you're looking for a replacement gauge, ensuring compatibility with your system's pressure range and mounting style is essential. The 60mm diameter is a popular choice for tight spaces while still offering a large enough dial for readability.
