Configure a Raytek Mi3 sensing head — LT, G5 glass, or 1M / 2M short-wave, with intrinsically safe and water-cooled variants and cable length built into the part number — then add the communication box (ordered separately, required to operate) and accessories, priced as you go.

For use with a Mi3 communication box, sold separately. Mi3100-series heads are sold by quote only.

Endurance, Thermalert, MP150 and ThermoView are engineered rep-firm lines — those are quoted, not sold here.

Web prices for this family run $489 to $7,952 depending on model, communication box and accessory selection. Use the quote form below and we’ll price your exact configuration by reply.
