HydroQuip M7 temperature sensor - 30 cm

This 12" (30 cm) HydroQuip M7 temperature sensor is an ideal replacement for the now-discontinued Balboa M7 model of the same length.

The sensor – supplied with its cable gland – is compatible with Balboa heaters using M7 technology. The M7 system uses two identical sensors, placed at each end of the heater. The sensors have two-pin plugs which connect to sockets on the motherboard of the hot tub control system.

Two versions of this sensor are used in Balboa control systems with integrated heaters: the 30 cm version is generally found in control systems housed in plastic boxes, while the 60 cm version is more commonly found in metal-boxed systems.

A third version, with a 90 cm cable, is used in systems where the heater is separate from the control box.
