ACR OWL Temperature Data Loggers
OWL 100 Single-Channel Internal 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.
Our OWL Series consists of configurable, single-channel data loggers with flashing visual alarms, optical data transfer, and an industry-leading 10-year battery life.
Key Features
- One channel with options to record temperature, electric current, voltage, or process current
- 32KB memory for almost 33,000 readings
- Configurable alarm thresholds and modes with super-bright red blinking annunciator
- Conformal coating protects electronics from harsh environments
- Industry-leading 10-year battery life
- 3-year warranty

OWL 200 Single-Channel External Temperature Data Logger
The OWL 200 data logger can record temperature or switch status in environments that typical data loggers cannot withstand. Since the OWL’s temperature sensor is external, the sensor can work in excessive heat while the logger remains in a cooler environment. Because of its small size and being fully battery powered, the OWL can also fit into tight spaces.
Our OWL Series consists of configurable, single-channel data loggers with flashing visual alarms, optical data transfer, and an industry-leading 10-year battery life.
Key Features
- One channel with options to record temperature, electric current, voltage, or process current
- 32KB memory for almost 33,000 readings
- Configurable alarm thresholds and modes with super-bright red blinking annunciator
- Conformal coating protects electronics from harsh environments
