Designed to record the thermal disinfection temperature reached during each washer cycle, the CycleCheck® indicates whether water reached the surface of the coupon during the cycle. Simply, peel the CycleCheck® from the release paper and adhere to the surface of the TOSI® rack. Once the selected cycle is chosen and ran, the color of the temperature indicator dots will change from white to black indicating the thermal temperature has been reached and the water indicator will change from black to yellow. The irreversible thermochromatic (heat sensitive) indicator next to the hydrophilic ink dot will register temperature levels of 82°C and 93°C. The CycleCheck® can be purchased in a case of twenty-four.
