Filled System Thermometers 01646

3D Instruments' filled system thermometers are superior to other temperature gauge systems because they provide an evenly graduated scale without the use of a multiplying mechanism or delicate geared segments, pionions or hair springs. This results in a more durable, rugged instrument suitable for installations which experience severe vibration and shock
