DP-CALC™
Micromanometers
|
| The
TSI DP-Calc 5815 and 5825 micromanometers allow you to easily make HVAC
pressure measurements. TheDP-Calc instruments can be used with Pitot probes
to measure duct velocity. The DP-Calc 5815 is a simple to operate, hand
held digital Micromanometer for fast, accurate differential and static pressure
measurements. The high performance DP-CALC™ 5825 can calculate flow
and has data logging capabilities. Features and Benefits

1
Overpressure range = 190 in. H2O (7 psi, 360 mmHg, 48 kPa).
2 Pressure velocity measurements are not recommended below 1,000 ft/min (5 m/s). 3 Accuracy is a function of converting pressure to velocity. Conversion accuracy improves when actual pressure values increase. Specifications are subject to change without notice |
