A measurement device is disclosed, embodiments of which are adapted to withstand, detect, and record detection of heat cycle events, including autoclave cycles. Embodiments of the measurement device comprise a sensor for measuring a characteristic of a medium and a heat cycle detection unit. Embodiments of the heat cycle detection unit comprise a temperature or pressure responsive element, a detection module, data interface, and data memory. In one disclosed embodiment, the temperature or pressure responsive element is configured to respond to a characteristic of a heat cycle event while the heat cycle detection unit is powered off. In another disclosed embodiment, the detection module is configured to automatically power off the heat cycle detection unit in response to detecting an autoclave cycle. Methods of using the devices are also disclosed. |
