Energy Logging Systems

The HOBO Energy Logger Pro Data Logger is a modular, re-configurable 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.

Innovative, snap-in FlexSmart™ signal conditioning modules convert signals from nearly any type of sensor. A suite of pre-defined plug-and-play smart sensors and powerful HOBOware® software make set-up and deployment fast and easy. You can also expand your system capabilities with Ethernet or remote data access communications.


Onset's most flexible data logger records up to 15 channels of over a dozen measurements
Provides 12v excitation for third-party sensors
Pre-configured smart sensors get you started fast
Signal conditioning modules retain configurations until you change them, providing plug-and-play convenience for commonly used sensors
Flexible power options include battery operation for AC power adapter

Operating range: -20° to 50°C (-4° to 122°F) with alkaline batteries
-40° to 60°C (-40° to 140°F) with lithium batteries
Sensor inputs: Three FlexSmart multi-channel modules and up to 6 Smart Sensors (which may have multiple parameters/channels)
Sensor connectors: Six RJ-12 Smart Sensor jacks plus 3 FlexSmart module slots
Communication: RS-232 via 3.5 mm serial port or/and 9-pin D-Sub connector
Dimensions: 15.6 cm x 8.4 cm x 4.6 cm (6.13" x 3.31" x 1.81")
Weight: 435 g (15.23 oz) with batteries 238 g (8.33 oz) without batteries
Memory: 512K nonvolatile flash data storage
Memory modes: Stop when full; wrap when full
Operational indicators: Six indicators provide logging and sensor network status
Logging interval: One second to 18 hours, user-specified interval (2-second minimum for two-channel S-FS-TRMSA operation)
Sensor excitation: 12 V DC at 200 mA total, with user-programmable warmup time on a per-channel basis
Battery life: One year typical use (up to 75 mA excitation with 10-minute or longer logging Interval and 1-second warmup time)
Battery type: Eight standard AA alkaline batteries included (for operating conditions -20°C/-4°F to 50°C/122°F); optional AA lithium batteries available for operating conditions of -40° to 60°C (-40° to 140°F).
External power: Supports optional 13.6 V DC regulated AC Wall Adapter Connector. Internal batteries may remain installed. Alternatively, an automotive battery or 9-12 V DC regulated Wall Adapter may be used, but it is recommended to remove the internal batteries since they will discharge to the level of the external supply.
Time accuracy: 0 to 2 seconds for the first data point and ±5 seconds per week at 25°C (77°F)
Logging mode: Immediate, timed delay, or trigger (button-push) start options; supports sampling intervals for some sensors
Data communication: Current readings while logging; read out while logging;
read out when stopped
This product meets CE specification EN61326 criterion C for ESD, criterion C for Radiated Immunity, criterion B for Fast Transient, criterion A for Conducted Immunity, and criterion A for Power Frequency Magnetic Fields. To minimize measurement errors due to ambient RF, use the shortest possible probe sensor cable length.
