In industries where accuracy is paramount, ensuring that pressure-measuring instruments deliver reliable data is non-negotiable. Calibration hand pumps play a critical role in this process. These portable, manually operated tools generate pressure or vacuum, allowing technicians to calibrate pressure gauges, transducers, transmitters, and other pressure instruments effectively. What Are Calibration Hand Pumps? Calibration hand pumps are devices designed to produce pressure or vacuum in a controlled and repeatable manner. Unlike digital pressure sources or bulky machinery, hand pumps are compact, easy to use, and do not require power, making them ideal for both field and laboratory calibration tasks. Their main purpose is to serve as a pressure source during the calibration of instruments, ensuring the devices provide accurate readings across a specified range. Types of Calibration Hand Pumps There are three primary types of calibration hand pumps: Hydraulic Hand Pumps These ar...
