WD-20250-13 Pressure and Flow Meter with NIST-Traceable Calibration by Digi-Sense
Ideal tool for helping HVAC field technicians determine the performance of heating and cooling systems. This handheld meter measures differential and static pressure, and calculates air velocity and flow. Meters are heavy duty, easily configurable, and feature a large backlit LCD. View measurement data in graphical formats as well as record and download data with included software for further analysis.
Features
- Reliable measurements, guaranteed! Precalibrated to NIST-traceable standards.
- Displays pressure, air velocity, and airflow plus environmental temperature
- Relative time clock on Max/Min/Avg readings provides a time reference for major events
- Save and recall up to 99 sample readings per parameter
- Data logging software with graphical display provides quick and simple data interpretation
- USB connectivity allows downloading of data to PC
- Large backlit LCD for clear reading in dimly lit environments
- Auto power-off extends battery life
Applications
- Evaluating duct performance and proper airflow
- Inspecting air filtration
- Monitoring HVAC operation in factories and warehouses
- Ensuring safe working conditions in office buildings and schools
- Adjusting motor speeds in HVAC systems
Includes
Pitot tube with two rubber hoses, USB cable, software CD, hard carrying case, battery, and NIST-traceable certificate with data and uncertainties.
