Portable temperature and humidity data logger
Omega Engineering’s OM-91 temperature and OM-92 temperature/humidity data loggers are designed for transportation applications where it is necessary to document that the material in-transit has stayed within particular environmental limits. 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. 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.
