Single Channel Ambient Temperature Data Logger
The OWL 100 data logger records temperature in environments that typical data log-
gers 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.
