The TSI Alnor DP-Calc 5815 and 5825 micromanometers are robust instruments that allow users to easily make HVAC pressure measurements and, when used with pitot tube probes, to measure duct velocity. The DP-Calc 5815 is a simple to operate, handheld digital micromanometer for fast, accurate differential and static pressure measurements. The high performance DP-Calc 5825 can also calculate flow and has data logging capabilities.
Typically used in HVAC commissioning and troubleshooting, the TSI Alnor DP-Calc micromanometers can measure differential and static pressure from -15 to +15 in. H2O (-3735 to +3735 Pa) and calculate and display velocity when using a pitot tube. Additionally, the TSI Alnor DP-Calc 5825 calculates flow, has a variable time constant, and features data logging of 12,700+ samples (100 test IDs) with time and date stamp.
The TSI Alnor DP-Calc micromanometers ship complete with hard carrying case, 4 alkaline batteries, operation and service manual and calibration certificate. The TSI Alnor DP-Calc 5825 also includes an 8-foot (2.4 m) rubber tube, static pressure tip, LogDat2 downloading software and USB cable.
