👉 Calibration fluid is a specialized liquid solution used to adjust and maintain the precision of various measurement instruments, such as pressure gauges, flow meters, and thermometers. It typically contains additives that modify the fluid's properties, like viscosity or surface tension, to ensure accurate readings by compensating for factors such as temperature changes or wear and tear on the instrument's components. Proper calibration with the correct fluid is essential for achieving reliable and consistent measurements across different operating conditions and over time.
