Have you ever jumped in the pool, only to immediately jump right back out because it's freezing? Or is there a pond on your property that you don't want to freeze? Do the kids need a jacket today? Now you can
know the water temperature with one quick glance at this wireless remote display with extra-large LCD numbers. You can even set an alarm to let you know if your aquarium water gets too hot or too cold. The indoor display advises the outside temperature and relative humidity, as well as battery condition and trend indicators. There's a history of the minimum and maximum temperatures for any length of time. Installation is easy: add batteries, mount the outdoor sensor in a spot protected from weather and direct sun, and float the other sensor in your pool or pond.
The indoor display, remote sensor, and floating transmitter each operate on two
AA batteries, sold separately. Using Lithium batteries extends the temperature range of the sensors. Note: do not allow the floating sensor to sit in freezing water; as the water expands due to freezing, it will damage the sensor.
