Solar Water Level Sensor, High/Low Water Level Alarm with Dual Probe, 129 dB Red Strobe Siren with Adjustable Volume, Bobber Water Detector, 16.4ft Detect Cord, IP55 Waterproof for Indoor /Outdoor

C'est super pour le prix en plus chaque sonde est réversible donc pour mon besoin à moi c'est en prévention de débordements donc j'ai 2 sondes en surveillanceAinsi que trois niveaux sonores impossible de ne pas l'entendre

This thing works great for my well tank that supplies our house. I put the low sensor about 2 feet from the bottom and put the high sensor right at the top where the tank necks down. When i'm filling it and i hear the alarm go off we cut the well off, then drain a few gallons of water and the alarm shuts off. I'm glad because this allows us to save water and not overflow the tank.The alarm is extremely loud. It is high pitched so the sound doesn't travel super far, but we are about 50 yards from the alarm and can hear it go off, we leave the window cracked to make it easier to hear. At point blank this thing will make your ears ring.I do wish there was an indicator that whenever you first turn the alarm on it beeps one time to let you know the batteries are charged. I wonder about that battery dying one day and we don't realize it, we rely on this to tell us if our tank ever gets too empty. I'll probably end up replacing the battery once every 6 months just to be on the safe side. Well worth the $35.

Está un poco corriente

Fitted in a sump around a swimming pool. Works perfectly to clear the ground water. Light and audible alarm warnings are great.

Inexpensive and very functional
