Our high - tech company, with more than 14 years of expertise since its founding, offers a portable manometer that is the epitome of precision and portability in pressure measurement. Ideal for applications in HVAC systems, plumbing, industrial pipelines, and automotive diagnostics, this manometer is designed to be easily carried and operated in various field conditions. Constructed with a robust yet lightweight housing, often made of high - strength ABS or aluminum alloy, it can withstand accidental drops and rough handling. The portable manometer is equipped with a highly sensitive pressure sensor, capable of measuring both positive and negative pressures across a wide range, typically from - 1 bar to 100 bar (- 14.5 psi to 1450 psi), with an accuracy of ±0.5% of full - scale reading. Its intuitive digital display, featuring large, clear digits, provides instant and easy - to - read pressure values, and some models include additional functions like backlighting for enhanced visibility in dim environments. The manometer offers multiple pressure unit conversions, such as psi, bar, kPa, and mmHg, catering to the diverse needs of different industries. To ensure reliable performance, it is designed with advanced calibration algorithms and can be easily calibrated on - site using simple procedures. With a long - lasting battery life and an auto - power - off function to conserve energy, our portable manometer also comes with convenient data - hold and maximum/minimum pressure recording features. Compliant with international safety and quality standards like CE, UL, and ISO, it is a trusted tool for professionals requiring accurate and portable pressure measurement in their daily operations.
