QUESTemp 36 Thermal Environment Monitor
The datalogging QUESTemp° 36 is the premier monitor within the QUESTemp°
Series of Thermal Environment Monitors. The QUESTemp° 36 further simplifies heat stress management efforts by
providing users with realtime guidance on stay times and work/rest
regimens. Guidance is based on screening criteria for heat stress as
defined in the ACGIH TLV Handbook,U.S. Navy PHEL Charts and EPRI Action
Limits. The QUESTemp° 36 eliminates the need to carry paper charts, pocket
guides and look-up tables into the field. An optional detachable probe for measuring air velocity extends the
applications for the QUESTemp° 36 beyond traditional heat stress
measurements. The QUESTemp° 36 can be used as an indoor thermal comfort
monitor using the air velocity probe, temperature and RH sensor readings
simultaneously. Other applications include verification of air flow in fume hoods or
rooms normally requiring a minimum amount of air flow to be safe for
occupancy.
