OM-92 is an OM-90 series temperature/humidity datalogger. The OM-90 Series is a portable, battery operated, temperature/humidity datalogger. Temperature is measured to an accuracy of ±0.3°C over the range of 5 to 60°C (41 to 140°F) and ±2.0°C over the full range of -30 to 80°C (-22 to 176°F). 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. This data logger is ideal for transportation applications where it is necessary to document that the material in-transit has stayed within particular environmental limits.
