Hotwires Made of gold-sheathed tungsten, rhenium-tungsten, nickel and nickel alloy. Each provides specific performance characteristics such as corrosion resistance, oxidation resistance, catalytic reactions and sensitivity for use under different application conditions.
Thermistors
Buck Scientific thermistor detector elements utilize the same mounts as hotwires.
A thermistor is a thermally sensitive resistor having a high negative co-efficient of resistance.
Thermistors have relatively low operating temperatures, and should not be used in hydrogen atmospheres.
They have high sensitivity at low temperatures and can be used at sub-ambient temperatures.
filaments are tested before shipment. Most filaments are tested and matched in helium but can be matched in other gases on special request.
