Gauges are measuring instruments used to monitor, measure, and display physical parameters such as pressure, temperature, level, thickness, and dimensions. They play an important role in inspection, control, and quality assurance across various industrial and technical applications. Gauges provide quick and reliable readings, helping operators ensure systems are functioning within safe and specified limits. Available in different types such as pressure gauges, temperature gauges, thickness gauges, and dial gauges, they are designed with varying measurement ranges, accuracy levels, and construction materials. Gauges are widely used in manufacturing, automotive systems, industrial machinery, laboratories, and maintenance operations, contributing to accurate monitoring, process control, and operational safety.
