Temperature sensor for Balboa M7 heaters. The M7 system uses two identical sensors placed at either 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 control systems with integrated heaters: the 36 cm version (shown in the photo) is generally found in control systems housed in plastic boxes, while the 60 cm version is more commonly found in metal-boxed systems.

Note that Balboa has recently lengthened the cable of the smallest version of its probes from 30 cm (12") to 36 cm (14").

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

Sensor diameter: 6.3 mm (1/4")
Plug: a 2-pin connector with a black wire and a red wire
