Frequently Asked Questions

Q: Can I use the wired probe in a fish tank or aquarium?

A: Yes! The 6.5 ft waterproof probe is specifically designed for submersion in aquariums, making it great for monitoring water temperature for goldfish, killifish, reptiles, and other aquatic pets. Just keep the main display unit out of the water, as it is not water-resistant.

Q: Does this digital thermometer show both indoor and outdoor temperatures at the same time?

A: Yes. The large LCD display shows the indoor ambient temperature alongside the external probe reading simultaneously, so you can monitor both environments at a glance.

Q: How do I switch between Celsius and Fahrenheit?

A: First, remove the AAA batteries from the unit, then press the C/F switch button to toggle between °C and °F. Re-insert the batteries to save your preferred unit. The thermometer defaults to Fahrenheit (℉) out of the box.

Q: How often does the Min/Max record reset?

A: The daily Min/Max temperature records reset automatically every 24 hours, so you always have a fresh reference for the day's temperature range without needing to manually clear the memory.
