Refractory cements and raw materials consist of castables, rams, aggregates and binders that are resistant to high temperatures.

Mechanical timers are used to actuate devices at the end of a specified time period.

Refractories and high temperature insulation include many different types of ceramic insulation, refractory shapes, and refractory cements.

Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency.

Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements

Seismic instruments are used to measure low frequency ground motion caused by earthquakes.

Continuous duty rotary solenoids convert axial motion into rotary stroke and are rated for 100% duty cycle.
