When calibrating critical temperature sensors—such as PRTs, thermocouples, and liquid-in-glass thermometers—uniformity is non-negotiable. Portable liquid calibration baths use advanced stirring mechanisms and precise fluid circulation to achieve exceptional temperature homogeneity, often within ±0.01°C. This is especially crucial in field environments where ambient conditions can skew results. Whether you’re validating sensors in a food processing plant or an energy substation, a portable liquid bath guarantees reliable, repeatable calibrations. Learn how high uniformity minimizes errors and meets ISO 17025 requirements even outside the lab.
