Check Wick and Fill Natural Wet Bulb The QUESTemp 32 uses a cotton wick immersed into a reservoir containing distilled water. DO NOT use ordinary tap water, as the contaminants that are left behind after evaporation will shorten the life of the wick and cause high readings. If the wick is discolored, it should be replaced.
Measurements Measurements QUESTemp32 Measurements QUESTemp32 The QUESTemp32 portable area heat stress monitor computes the Wet Bulb Globe Temperature (WBGT). The WBGT is an accepted measurement for determining the heat stress level imposed on an individual in a given environment. The QUESTemp32 measures three parameters: ambient or dry bulb temperature (DB), natural wet bulb temperature (WB), and globe temperature (G).
Measurements Heat Index / Humidex Heat Index / Humidex The Heat Index is determined using the dry bulb temperature and relative humidity. Based upon charts available from the U.S. National Weather Service, Heat Index represents how an average person feels relative to climate conditions. For a constant temperature, if the humidity rises, so does the heat index.
Keypad Keypad Operation Heat Index / Humidex Operation Keypad Operation The unit operates using a membrane keypad with four keys. The I/O ENTER key responds when the key is released while all other keys respond when the key is pressed. Keys Explanation I/O Enter key...

Placement for Monitoring/Testing Placement Natural Wet Bulb Thermometer Placement for Monitoring/Testing The QUESTemp° 32 should be placed at a height of 3.5 feet (1.1 m) for standing individuals or 2 feet (.6 m) for seated individuals. Tripod mounting is recommended to get the unit away from anything that might block radiant heat or air flow.
Sensors Dry Bulb Thermometer Dry Bulb Thermometer The dry bulb thermometer measures the ambient air temperature. This measurement is used in the outdoor WBGT calculation when a high solar radiant heat load may be present. The series of white plates surrounding the sensor shield it from radiant heat. Relative Humidity Sensor A relative humidity sensor is located in a compartment inside of the sensor bar housing.
Remote, Remote, Sensors 2 and 3 Tri-Sensor Weighted Average Sensors 2 & 3 Remote, Sensors 2 and 3 The top sensor bar (sensor 1) may be removed from the instrument and used through a remote cable. Shelter the instrument and remote the sensor bar if the measured environment is expecting heavy rain or if temperatures are above 60C.
9-V Alkaline Battery Replacement Power Options There are 3 options for powering the QUESTemp 32: a 9-volt alkaline battery, a NiMH (Nickel Metal Hydride) rechargeable 6-cell battery pack, and an AC adapter. A door on the back of the unit allows the user access to the 9-volt battery. The rechargeable battery pack is located inside of the unit.
Battery Pack Power Options NiMH Battery Pack NiMH Battery Pack WARNING : Recharge batteries only in a non-hazardous environment. The NiMH rechargeable battery pack is charged in the instrument using TSI’s AC adapter #015-910. A discharged battery pack requires an “overnight” charge of 16 hours.
Appendix A: Specifications Power Options 9V alkaline, 7.2V NiMH rechargeable pack (charged in the unit), or AC adapter wall power cube (AC adaptor will operate the unit or recharge the NiMH battery pack). Battery Life 9V alkaline: 140 hours ...
