QUESTemp° II is an easy-to-use personal heat
stress indicator that monitors an individuals
body temperature for indications of the onset
of heat stress. The QUESTemp° II is intended
to be a part of a well-managed heat stress safety
program. It is an alerting device that warns the
user that their personal body temperature has
risen above the "safe" level and that
action should be taken to allow the body to cool.
The QUESTemp° II consists of a belt or pocket
worn device with a thin, flexible cable leading
up to a small earmold that contains the sensor
and a small speaker for an audio alert. The sensing
device protrudes from the earmold and a disposable
E.A.R.® foam earplug slides over the sensor
providing a comfortable vehicle for inserting
and maintaining the sensor. The speaker and earmold
remain just outside of the ear to completely avoid
any possible damage or injury to the ear canal.
the datalogging QUESTemp° 34 and 36 area
monitors, the QUESTemp° II interfaces with
QuestSuite Professional software for fast and
convenient data storage, retrieval, analysis,
reporting and charting. Using QuestSuite Professional
in conjunction with QUESTemp° Series personal
and area monitors enables powerful correlations
to be developed between environmental conditions,
physical activity, clothing types and real physiological
impact on an individualized basis.
II Technical Specifications
The QUESTEMPºII temperature sensor has
an electronic accuracy of better than +/-0.1ºC
over the temperature range of 32ºC to 40ºC.
(Body temperature range.)
Using one 9-volt ALKALINE (type NEDA 1604A)
battery, the QUESTEMPºII, under normal
usage, should last approximately 60 hours. It
will also continue to operate for a minimum
of 8 hours after the LOW BATTery indicator first
A 3 volt lithium battery is used as backup power
for the real-time clock and the memory.
Working Temperature Range:
The unit itself has an operating temperature
range of 0ºC to 70ºC.
If the unit is to be stored for prolonged periods,
the battery should be removed.
Operate between 0% - 95% humidity (non-condensing).
2.5 x 5.1 x 1.0 inches (64 x 130 x 25mm)
Housing: 10 ounces (283 grams)
Ear Sensor Assembly: 0.15 ounces (4.2 grams)
The electronics are housed in a rugged cast
The earmold is constructed from an FDA approved
QUESTemp° 34 builds even further upon the
value found in the QUESTemp° 32 model by providing
datalogging of all measurement information.
QUESTemp° 34 interfaces with QuestSuite
Professional software for fast and convenient
data storage, retrieval, analysis, reporting
Professional software and the QUESTemp°
34 open the door to transforming your heat stress
monitoring data from an island of information
into "The System Solution" to occupational
and environmental exposure monitoring and information
management. Only with QuestSuite Professional
software are you able to manage not only data
from heat stress monitors, but also noise dosimeters,
sound level meters, vibration monitors, gas
detectors and IAQ monitors. All in one convenient
place through one simple user interface.

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

Temperature: 1000 ohm platinum RTD
Humidity: Integrated circuit with capacitive
Temperature: +/-0.5°C between 0°C and
Relative Humidity: +/-5%
Operating Temperature Range:
Sensor Assembly: -5°C to +100°C
Electronics: -5°C to 60°C
Operating Relative Humidity Range:
0 to 100% (extended exposure to humidity >
90% can cause a reversible shift of 3%)
Remote Sensor Bars:
2 x 15pin D-sub jacks are located on the side
of the unit for plugging in 1 or 2 additional
sensor bars by using remote cables up to 200
feet (61m). The top sensor bar can also be remote
with a cable.
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)
9V alkaline: 140 hours
Rechargeable Nickel Metal Hydride: 300 hours
(Adding additional sensor bars to the QUESTemp°34
reduces battery life.)
Charge Time (NiMH Battery Pack): 16 hours (charge
in the unit)
