• Models for Temperature (OM-91) and Temperature/Humidity (OM-92) • Low-Cost Calibration Options • Free Software for Windows XP/Vista/7/8/10 (32-bit and 64-bit) • Immediate, Delayed (Specific Date/Time) or Pushbutton Start • Real-Time Mode • User-Configurable High and Low Alarms • LED Status Indicators • USB Interface for Fast Data Transfer • Compact, Light Weight, Easy-to-Use • Long Battery Life The OM-90 Series are portable, battery operated, temperature (OM-91) and temperature/humidity (OM-92) data loggers. Temperature is measured to an accuracy of ±0.3°C over the range of 5 to 60°C and ±2.0°C over the full range of -30 to 80°C. Relative humidity is measured to an accuracy of ±3.0% RH over the 20 to 80% RH range and ±5.0% RH over the 0 to 100% RH range. Both temperature and relative humidity are logged at a user configurable logging rate which is software selectable. These data loggers are ideal for transportation applications where it is necessary to document that the material in-transit has stayed within particular environmental limits. High/low alarm limits can be set above or below which LED indicators will be activated so that the user can become aware that the desired transportation conditions have been exceeded. Each data logger can be assigned a 16 character name. This can be helpful in applications where multiple data loggers are used and there is a need to distinguish between them (for example based on location). The data logger includes a very easy to use software application.
