What is the minimum reading increment for a digital gauge?

The minimum reading increment for a digital gauge is often designed to provide precise measurements suitable for high-pressure applications. A reading increment of 1/100 of a psig allows for a detailed assessment of pressure levels, which is essential for safe and efficient operation in high-pressure environments like those found in boilers. This fine level of granularity helps operators to detect small changes in pressure that could indicate a problem or a need for adjustment, thus enhancing safety and performance.

In high-pressure boiler operations, accuracy in measuring pressure is crucial, making it essential for the gauges to provide sufficiently small increments to facilitate effective monitoring and control. The ability to read at this level ensures compliance with regulations and operational standards, minimizing risks associated with pressure fluctuations. Consequently, this is why a digital gauge that increments by 1/100 of a psig is the correct answer in this context.
