Single Channel Ambient Temperature Data Logger
The OWL 100 data logger records temperature in environments that typical data
loggers cannot withstand. This model is also available in a water-resistant
polyurethane enclosure (OWL 100-Poly) so it can be used in hostile environments
where vibration or excess moisture is present.
Single Channel Temperature (Thermistor) Data Logger
The OWL 200 data logger can record temperature, resistance, or switch status. It can
be placed in tight environments where typical data loggers cannot fit. Connect any
one of ACR’s ET series thermistor probes to the logger and begin recording. Monitor
and record high temperature, low temperature, pipe surface, skin surface, or a variety
of other temperatures.
