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

Accuracy:
The QUESTEMPºII temperature sensor has an electronic accuracy of better than +/-0.1ºC over the temperature range of 32ºC to 40ºC. (Body temperature range.)
Battery Life:
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 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 0ºC to 70ºC.
Storage:
If the unit is to be stored for prolonged periods, the battery should be removed.
Operating Humidity:
Operate between 0% - 95% humidity (non-condensing).
Size:
2.5 x 5.1 x 1.0 inches (64 x 130 x 25mm)
Weight:
Housing: 10 ounces (283 grams)
Ear Sensor Assembly: 0.15 ounces (4.2 grams)
Construction:
The electronics are housed in a rugged cast aluminum case.
The earmold is constructed from an FDA approved GEON.

The QUESTemp° 34 interfaces with QuestSuite Professional software for fast and convenient data storage, retrieval, analysis, reporting and charting.

QuestSuite 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.

QUESTemp 34 Technical Specifications

Measurements:
Globe, dry bulb, wet bulb, WBGTin, WBGTout, WBGT weighted average (if 3 sensor sets), relative humidity, and Heat Index / Humidex.
Temperatures given in Celsius or Fahrenheit.
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.
Size:
Height 9.2in (23.5cm); Width 7.2in (18.3mm); Depth 3.0in (7.5mm)
Dimensions include mounted sensor assembly
Weight:
2.6 lbs. (1.2 kg) with mounted sensor assembly
Sensor Types:
Temperature: 1000 ohm platinum RTD
Humidity: Integrated circuit with capacitive polymer sensor
Accuracy:
Temperature: +/-0.5°C between 0°C and 100°C
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.
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
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)
Safety Approvals:
ETL, cETL: Class I,II,III Groups A,B,C,D,E,F,G, Temperature code T3 DEMKO: EEX ia IIC, T3
CE mark
