Approximately how many days of continuous reading is the expected life of the hygrometer's batteries?

The expected life of the hygrometer's batteries, which is approximately 300 days of continuous reading, is based on the energy consumption of the device and the capacity of the batteries used. This lifespan indicates that the hygrometer can function effectively for a considerable duration without requiring a battery change, making it reliable for ongoing monitoring of humidity levels in aircrew flight equipment. Understanding this specification is crucial for maintaining operational readiness and ensuring that the hygrometer remains functional during essential periods.
