Casella Microtherm Heat Stress Monitor Kit ensures worker safety in hot environments
Features & Applications:
Workers exposed to hot working environments can be susceptible to heat stress, when the core body temperature rises to dangerous or hazardous
levels. This can result in physiological symptoms like heat cramps, nausea,
palpitations, stroke and possibly death. An overall estimation of the heat stress levels on a body can be measured using the Wet Bulb Globe temperature (WBGT) Index. This combines the results from three temperature sensors into a single calculated value that may be compared with reference values depending upon the specific work regime.
Kit Includes:
- Microtherm monitor with 3 sensor temperature probe
- Pack of 5 spare wicks for wet themometer sensor
- Plastic bottle for distilled water storage
- Download cable to pc
- Heat stress pc software for viewing measurements
- 4 x AA size rechargable NiCad batteries
- Worldwide power supply and charger unit for battery pack
- Operator manual
Features:
- Large LCD screen
- Real time display of changing levels
- Data-logging as standard
- Low water level alarm
- Audible & visual warning of level excedances
- RH% and dew point calculation
- Windows PC software for setup and download of results from memory
- Automatic calculation of work/rest regimes with included PC software
- Tripod mounting for extended surveys
- Meets the requirements of ISO 7243
Applications:
- Power stations
- Foundries
- Steel works
- Bakeries
- Glass manufacturing
- Routine monitoring
- Medical surveillance testing
