QUESTemp II Datalogging Personal Heat Stress Monitor

Pine Item #51427

The QUESTemp II is an easy-to-use personal heat stress indicator that monitors an individual’s 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.

Like 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.

QUESTemp II Technical Specifications


The QUESTEMP ºII temperature sensor has an electronic accuracy of better than +/-0.1 ºC over the temperature range of 32 ºC to 40 ºC. (Body temperature range.)

Battery Life:

Using one 9-volt ALKALINE (type NEDA 1604A) battery, the QUESTEMP ºII, 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 comes on.
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 0 ºC to 70 ºC.


If the unit is to be stored for prolonged periods, the battery should be removed.

Operating Humidity:

Operate between 0% - 95% humidity (non-condensing).
