Appendix A: Specifications
Measurements
Globe temperature, dry bulb temperature, wet bulb temperature, % relative
humidity, WBGTin, WBGTout, WBGT weighted average (if 3 sensor sets), and
Heat Index / Humidex.
Temperatures given in Celsius or Fahrenheit.
Index (QT
º
46 only): ACGIH TLV, U.S. Navy PHEL Charts,
Flag Conditions for U.S.
Navy/Marine Corp. Ashore, and EPRI
Data Logging
Records and prints all measurements at user selected interval of 1, 2, 5, 10, 15, 30,
or 60 minutes. 128K bytes of data memory.
Languages
English, French, Spanish, Italian, German
Housing
Designed water resistant to a light rain or mist. If rain is frequent, best practice
would be to remote the sensor bar and keep the instrument sheltered.
