TSI’s DP-Calc™ Micromanometers allow you to easily make HVAC pressure measurements.
TSI’s DP-Calc™ Micromanometers allow you to easily make HVAC pressure measurements. The DP-Calc measures static, total, and velocity pressures as well as pressure drops across filters, coils, fans, and diffusers. The microprocessor-based DP-Calc uses the latest electronic pressure transducer technology, eliminating sensitivity due to the orientation of the meter. Each model of the DP-Calc combines a lightweight and durable design with an easy to read display.
Model 8702/8705 Features
Zeroing function quickly resets instrument zero to ensure accurate measurements
Calculates and displays a velocity reading when using a Pitot tube
Variable time constant modes available for a steady display when measuring fluctuating flows
Sampling function takes a sample and stores the current reading
Optional portable printer provides hard copy documentation of your measurements
NIST* traceable calibration certificate
Additional Features of Model 8705
Data logging ability allows user to log 1000 data points with a time and date stamp
Data can be reviewed on-screen, printed, and downloaded to your computer spreadsheet program
TSI downloading software permits easy transfer of data to a computer
Statistics function displays average, maximum and minimum values, and the number of recorded samples
Automatic conversion between actual and standard velocity readings
Flowrate feature allows for simple and quick calculations of volumetric flowrate by simply inputting the duct shape and size
K factor function provides flexibility for measuring flowrates in various applications
