Variations:
 
OWL 100
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.
  • 32KB Memory
  • Total Accuracy: +/- 0.5° C @ 25° C (0.9° F @ 77° F)
    (Can be increased by using narrow range feature)
  • Resolution:0.5°C (0.9°F) at 25°C (77°F); better than 1°C (1.8°F) between -25 and 70°C (-13 and 158° F); better than 2.0°C (3.6°F) between -40 and -25°C (-40 and -13°F) (Can be increased by using narrow range feature)
  • Submergence Rating (OWL 100-Poly only): IP67: 1m in fresh water for 30 minutes
 
 

OWL 200
Can record temperature or switch status in environments that typical data loggers cannot withstand. Since the OWL's temperature sensor is external, it can work in excessive heat while the logger remains in a cooler environment. Because of its small size, the OWL can also fit into tight spaces.
  • 32 KB Memory
  • Logger Accuracy: +/- 1% of range
ET Series Thermistor Probe (OWL 200 works with any NTC thermistor probe)
 
General Purpose: -35 to 95°C (-30 to 200°F)
Low Temperature: -60 to 55°C (-75 to 130°F)
Low Temp Penetration: -60 to 55°C (-75 to 130°F)
High Temperature: 10 to 170°C (50 to 335°F)
Oven Temperature: 70 to 255°C (155 to 490°F)
Skin Surface Temp: 20 to 40°C (68 to 104°F)
Pip Surface Temp: -35 to 95°C (-30 to 200°F)
Waterproof Temerature: -40 to 105°C (-40 to 221°F)
 
 
 

OWL 300
Records current in environments that typical recorders cannot withstand. Due to its small size, the OWL 300 can go directly into an electrical panel or even inside small electrical equipment allowing the user to record electric current in a safe, discreet, and convenient manner.
  • Frequency Ranges: 60 Hz (with A60FL and A70FL current probes)
    50 Hz (with A65FL and A75FL current probes)
  • Current Ranges: 5, 25, 100, 250 Amps (with OWL-A60FL and OWL-A65FL current probes)
    10, 50, 250, 500 Amps (with OWL-A70FL and OWL-A75FL current probes)
  • Logger Accuracy: +/- 4% of full scale above 10% of range
 

OWL 400
A rugged and versatile data logger that records DC voltage with ease and convenience. This logger is ideal for monitoring (through commercially available transducers) a wide variety of measurement parameters. All voltage signals can be converted into custom engineering units using the simple equation editor in ACR's TrendReader 2 software.
  • Input Range: 0 to 38.4 Volts DC (32 software selectable ranges available)
  • Accuracy: +/- 1% of full scale
  • 32 KB Memory
  • Input Impedance: Greater than 100 K ohms
 
 

OWL 500
A rugged and versatile data logger that records the popular 4-20mA process signal with ease and convenience. This logger is ideal for monitoring (through commercially available transducers) a wide variety of measurement parameters. All DC current process signals can be converted into custom engineering units using the simple equation editor of ACR's TrendReader 2 software.
  • Input Range: 0 to 24 mA DC
  • Accuracy: +/- 1% of full scale
  • 32 KB Memory
  • Input Impedance: 100 Ohms
