Neptune Sonde de température des systèmes pour contrôleurs Apex

Reef Supplies has a decent selection of products at good prices.

These temperature proves last a long time but they eventually start to fluctuate from true. Recalibration helps but will only last so long.

RS had a replacement in stock at a good price and shipping was fairly quick.

Great product as always

If you have an Apex you already know how this little probe is a life saver It’ll closely monitor your tanks temperature and warn you of any thing that can go wrong over heating or broken heater causing sudden drop in temperature

As advertised and very reliable.
