Breaking Down the Features of Extech Instruments Manometer, Heavy Duty

Specifications

The Extech Instruments Manometer, Heavy Duty is engineered to measure pressure differentials and gas pressure with impressive sensitivity. It boasts a wide-range capability of 0 to 29 psi, offering a resolution of 0.02 psi. This level of precision is crucial for applications where even slight pressure variations are significant. The unit features 8 selectable units of measure, providing flexibility for various international standards and specific industry needs. A key function is the zero function for offset measurements, allowing for accurate readings relative to a specific baseline, which is incredibly useful in comparative testing. Further enhancing its utility are the min/max functions and a data hold feature, enabling the capture and retention of critical readings. The inclusion of an auto power off function conserves battery life, a practical consideration for extended field use. Finally, its built-in RS232 interface and accompanying Data Acquisition software or Data logger capabilities elevate it beyond a simple meter, allowing for detailed logging and analysis of pressure trends over time.
