Aim RSS-214 Heat Stress Monitor
High Reliability - Dust and splash proof construction provide a solid Mean Time Between Failure (MTBF) rate of 171,000 hours.
Fast Responding - Direct reading of outflow and inflow WBGT, WB, and GT values. Globe equivalent temperatures typically requires three minutes.
Accurate - Calculates to 1/100th degree and displays to 1/10th degree.
Easy Operation - At the push of a button, the RSS-214 calculates time weighted mean BGT, metabolic rate and work rest ratios.
Optional Data Logging:
- The optional data logger allows up to 511 records of data to be stored and output later through the serial port. The data logger must be purchased installed.
- Data can be logged manually or at pre-selected intervals of 0.5, 1, 2, 5, 6, 10, 20 or 30 minutes.
- Current sensor data may be viewed while logging. The data transmission is controlled by the computer and printer and does not interfere with logging.
- Most recent data is transmitted first.
- Data is secure, even if the battery fails or is removed.
- Data output record provides record number, data and time, WB, DB, GT, In WBGT and Out WBGT.
Software provides ease of data storage and retrieval and calculates time weighted mean WBGT and time weighted metabolic rates.
