Temperature Monitors: Rent or Buy
Temperature is a fundamental physical parameter in occupational health and safety, with both heat and cold extremes posing significant hazards to workers. Heat stress occurs when the body's thermoregulatory system is overwhelmed by a combination of metabolic heat generation and environmental heat load, potentially leading to heat cramps, heat exhaustion, and life-threatening heat stroke.

Monitoring Equipment to Rent for Temperature
Personal monitors are worn by each worker and record that worker's own exposure. Area monitors measure at a fixed point, room or job site. Pick a style below, then compare every option in the table.

Wearable heat-strain monitors
Worn on the upper arm against the skin. They track each worker's own heart rate, core body temperature and exertion rather than the air around them, so they are compared separately from the instruments above.
