Onset hobo U12-012, 4-external channel data logger
What I have today is a HOBO Datalogger model number U12-012 and a CTV-E.
U12 Temp/RH/Light/External Data Logger
Onset HOBO Four Channel USB Temperature/Humidity/Light/External Input Data Logger with 12-bit resolution
HOBO U12 Temperature, RH, Light and External Inout Data LoggerThe temperature, RH, light with external input logger is a four-channel electronic recording device that provides temperature, relative humidity, relative indoor light level measurements and accepts one external input. The external channel accepts a wide range of external sensors and input cables for temperature, CO2, AC Current, 4-20mA, and DC Voltage. The data logger features 12 bit resolution, high accuracy, data storage of 43,000 samples and 1 year user-replaceable battery.
List of Available External Sensors. (Temperature, AC Current, 0-2.5 Volt DC and 4-20 mA)
NOTE: NIST Calibration is available.

Logging and Measuring AC Current
Onset s split-core AC current sensors can be plugged directly into any of the HOBO H8 series or HOBO U12 series of data loggers that have external input channels. Use the the HOBO external input data loggers shown below to data log AC currents in the ranges of 0-20, 0-50, 0-100, 0-200, and 0-600. Some models include other built-in sensors (e.g, temperature, relative humidity, light intensity) or have the capability to accept other external probes and inputs (e.g., temperature, DC voltage, 4-20mA).
* Range available (AC Amps): 0-20, 0-50, 0-100, 0-200, 0-600
* Accuracy with H8 series of data loggers: 5.0% of full scale
* Accuracy with U12 series of data loggers: 4.5% of full scale
* Response time: CTV-A approximately 440 milliseconds, CTV-B approximately 200 milliseconds, CTV-C approximately 100 milliseconds, CTV-D approximately 450 milliseconds, CTV-E approximately 490 milliseconds (from 10% to 90% of amplitude)
* Input current: AC current, sine wave, single phase 50 Hz or 60 Hz, load power factor 0.5 to 1.0 lead or lag
* Construction and operating environment: Molded plastic housing for indoor use per UL508; pivoting leg (leg on CTV-D and CTV-E units is fully removable).
* Meet all CE Compliance Standards
