Weighing 4 oz and powered by a built-in 3.6-V lithium battery, the compact Series DL7 differential pressure datalogger is designed to measure and record low differential pressures down to ±1.2 mbar (0.5 in. wc) and temperatures from 32° to 158°F. The unit's accuracy and ability to store up to 21,500 readings make it ideal for monitoring air duct velocity, testing and balancing hvac systems, and verifying room pressures, says the company. The datalogger uses an on-board thermistor for ambient temperature measurement.
