Onset H22-001 HOBO H22 Energy Data Logger (-20°~50°C/ 40°~60°C)

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

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 bas

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)
