The Magnetic Probe Rack is a new accessory from Neptune Systems LLC that is specifically designed to take advantage of a growing suite of aquarium probes and sensors. One of the aesthetic ways that Neptune Systems designed the Magnetic Probe Rack to stand out from other similar devices, is by having an amazing finish.
The functional ways this Magnetic Probe Rack stands out is by having four holes for holding an array of various aquarium sensors.
Temperature, pH, conductivity and ORP can all be accommodated and there is even one hole which is enlarged to accept the fat tip of the Apex temperature sensor; no more stringing this sensor wire first through other probe holders in order to get it to fit.
The strong magnets of the Magnetic Probe Rack can clamp this probe holder down onto aquariums and sump walls up to half an inch thick.
