Measurement probe with heat cycle event counter

A system, comprising:

• a measurement device adapted to withstand and automatically count a heat sterilization or cleaning cycle, comprising:
• a measurement probe comprising a sensor configured to detect a characteristic of a medium and generate a measurement signal;
• a condition responsive element comprising either a temperature responsive element or a pressure responsive element;
• and
• a heat cycle detection unit comprising a detection module, a data interface, and a data memory;
• wherein the detection module is configured to:
• detect a heat cycle event using the condition responsive element, and
• record detection of the heat cycle event in the data memory,
• wherein the measurement device is configured to automatically power off the heat cycle detection unit after detection of the heat cycle;
• and
• a handheld device connected to the measurement device, the handheld device comprising:
• a screen;
• a button;
• a communication circuit configured to communicate with the measurement device and a computing device;
• and
• a processing system 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 cycle event count of the measurement device.
