The HOBO H22-001 Energy Data Logger is a multi-channel modular, reconfigurable data logging system for energy and industrial monitoring applications. The 15-channel system enables energy and facility management professionals to quickly and easily solve a broad range of monitoring applications without having to purchase a toolbox full of data loggers.

The H22-001 supports measurements of temperature, relative humidity, dew point, 4-20mA, AC current, AC voltage, air velocity, amp hour, carbon dioxide, compressed air flow, DC current, DC voltage, differential pressure, gauge pressure, kilowatt hours, kilowatts, power factor, pulse input, volatile organic compound, volt-amp reactive, volt-amp reactive hour, volt-amps, water flow, watt hours, watts and wind.

It features 6 RJ-12 Smart Sensor jacks plus 3 FlexSmart module slots for customizing inputs. Pre-configured Smart Sensors enable fast setup, and the logger provides 12V excitation for third-party sensors. Memory is 512 KB nonvolatile flash with user-specified logging intervals from 1 second to 18 hours. Operating range is -20° to 50°C with alkaline batteries and -40° to 60°C with lithium batteries.
