The Extech 407910 Differential Pressure Manometer is a versatile instrument designed for accurate measurement of differential pressure. This manometer is ideal for a wide range of applications, including HVAC systems, clean rooms, and industrial processes.The Extech 407910 offers a measurement range of up to 29 psi, allowing for precise and reliable readings in various pressure conditions. It can display the results in eight different units of measure, providing flexibility to meet specific measurement requirements.The manometer features a zero function, which allows for offset measurements. This function enables you to nullify any offset in the pressure readings, ensuring accurate and precise measurements in different scenarios.The Min/Max function captures and displays the minimum and maximum pressure values recorded during a measurement session. This feature is particularly useful for tracking pressure fluctuations and identifying potential issues.With the Data Hold function, you can freeze the displayed reading on the screen, making it easy to record or take notes without the need for constant monitoring. The Auto power off feature helps conserve battery life by automatically turning off the manometer after a period of inactivity.The Extech 407910 is equipped with a built-in RS232 interface, allowing for seamless connectivity to external devices such as a computer or data logger. This interface enables you to transfer and analyze the measured data directly on your PC or log the data for further analysis and reporting.To enhance the functionality and data management capabilities, optional Data Acquisition software or a Data logger can be used with the manometer. These tools provide advanced features for data analysis, trending, and reporting, facilitating comprehensive monitoring and documentation of pressure measurements.
