A system comprising a measurement device and a handheld device is disclosed, the system adapted to withstand, detect, record, and display heat cycle event counts. The measurement device comprises a sensor for measuring and a heat cycle detection unit. The heat cycle detection unit comprises a temperature or pressure responsive element, a detection module, data interface, and data memory. The handheld device comprises a screen, a button, a communication circuit, and a processing system. The communication circuit is configured to communicate with the measurement device and a computing device and the processing system is configured to receive non-measurement information from the measurement device, display the received information on the screen, and cycle the received information displayed on the screen based on an actuation of the button, wherein the handheld device is used to display a heat sterilization cycle count of the measurement device.

Measurement probe with heat cycle event counter

Cycle count instrument

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 atmospheric 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 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.
