RSS-214 Heat Stress Monitor

Pine Item #

Overexposure to heat is high on anyone's priority list for improving workplace safety, whether the heat is found at a construction site in the middle of the summer, or in a glass and ceramics manufacturing operation. The RSS-214 monitors area temperature in any setting, indoors or out. Its patented globe temperature sensor is highly responsive, typically less than three minutes for the RSS-214 compared to 20 minutes or more with a conventional Vernon globe. A unique self-diagnosis feature at every power-up berifies proper monitor operation. The instrument provides direct read of outdoor and indoor WBGT, and calculates time weighted mean WBGT, metabolic rates and work-to-rest ratios. Temperature can be displayed in degrees celsius or Fahrenheit.

Features:

Fast response time

17 hours continuous operation

511 records of data storage

Optional add-in Data Logger

Displays to 1/10th degree

Direct reading of Wet Bulb, Dry Bulb, and Vernon Globe equivalent

In/out temperatures at 95% accuracy in less than 4 1/2 minutes

Applications:

Designed to measure environmental factors that contribute to heat stress

Datalogging heat stress monitor measures dry bulb, wet bulb, and globe temperature

Weight12 oz. (350g)
ReadoutDirect read LCD
Readings
  • Indoor wet bulb globe Temperature (IN WBGT)
  • Outdoor Wet Bulb Glope Temperature (OUT WBGT)
  • Wet Bulb (WB)
  • Dry Bulb (DB)
  • Globe Temperature (GT)
WBGT Value Calculations
  • WBGT (outdoor) = 0.7 WB + 0.2 GT + 0.1DB
  • WBGT (indoor) = 0.7 WB + 0.3 GT
  • WB = Wet Bulb; GT = Vernon Globe Equivalent Temperature; DB = Dry Bulb)
Reading Resolution0.1 °C/0.1 °F
Calibrated Ranges25 °C (77 °F); 45 °C (113°F); 60 °C (140 °F)
Response
  • Electronics < 3 seconds (provided sensors are acclimatized)
  • Sensors (90% accuracy) <2.2 minutes
  • Sensors (95% accuracy) <4.5 minutes
Sensors
  • Globe Temperature (GT) - Construction provides characteristics identical to 6" Vernon Globe
  • Dry Bulb (DB) - Ambient air temperature
  • Wet Bulb (WB) - Wick-covered sensor with reservoir, wetted with deionized or distilled water
