Owl 200 – External Temperature

SKU: 01-0251
Model: OWL-200 PLASTIC

Single channel, 8 bit, 32 KB data logger (One external temperature channel).

Product Features

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, 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.

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-years warranty
