Heat Stress Monitor
The portable, rugged Romteck Heat Stress Monitor* (HSM) is an essential tool for occupational and environmental health and safety (OEHS) professionals to measure radiant temperature, dry bulb ambient temperature, relative humidity, wind speed, and air pressure parameters that affect heat stress in various conditions from industrial workplaces to underground mines. Heat stress reduces productivity and can lead to accidents, illness and even death. Prolonged exposure to high temperatures can lead to excessive fluid loss, shock or heat stroke. The HSM has applications in the military, foundries, agriculture, offshore drilling operations, food industry, engineering, sports, and industry. Due to its rugged design and anemometer for measuring wind speed, the HSM is well suited for monitoring in underground mines. OEHS professionals find the HSM ideal for confirming the appropriateness of work clothing and personal hydration practices to prevent heat stress. If left for unattended monitoring the HSM should not be placed on the ground due to the effect of radiated heat but mounted on a tripod.
