Dwyer Instruments DL71 | Differential pressure datalogger | Range ±1" w.c. (2.5 mbar)
The Model DL7 Differential Pressure Data Logger allows you to track and record low differential pressures as well as temperatures. A thermistor on board allows the unit to measure the outside temperature. Sample times can be adjusted by the user from 0.04 seconds to 8 hours, with choices for fill-then-stop or first-in, first-out sampling. With a built-in lithium battery, loggers may function completely without the need for an external power source and store up to 21,500 readings. To easily program the logger or transfer data to a computer, use the Model DL200 Windows® software (separately offered). The DL7 series logger is perfect for air duct velocity monitoring, HVAC system testing and balancing, and room pressure verification.
