OM-EL-USB-1 for possible alternatives.

OM-40 Series dataloggers can record temperature, relative humidity, 4 to 20 mA and 0 to 2.5 Vdc signals.

Model OM-41 measures temperature only (internal temperature sensor).

Model OM-42 is a two channel datalogger that measures temperature (internal sensor) and also one external signal which can be an external temperature probe, 4 to 20 mA signal or 0 to 2.5 Vdc signal.

Model OM-43 measures temperature and relative humidity (internal sensors).

Model OM-44 is a four channel datalogger that measures temperature and relative humidity (internal sensors) and also up to two external signals which can be external temperature probes, 4 to 20 mA signals or 0 to 2.5 Vdc signals. The internal temperature sensor is on a 4-inch wire which is mounted on the circuit board inside the snap lid of the datalogger case. Typically this sensor is left inside the case and measures ambient air temperature over the operating temperature range of the logger -20 to 70°C (-4 to 158°F). The internal temperature sensor can also be placed outside of the case, for faster response time. When the sensor is placed outside of the case it is capable of measuring temperatures from -40 to 120°C (-40 to 248°F).
