Amplifier and comparator chips are board-level components for amplifying voltage, current, or power.

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. They do not require electrical power and can be stored for long periods of time

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. They can provide the user with a clear and precise window into the frequency spectrum

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

Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions.

Power operational amplifiers (POA) are used to increase the power of low-level signals in applications that drive low impedances or reactive loads. They dissipate excess energy as heat, deliver extensive current, and can sustain relatively high supply voltages.

Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. PWM amplifiers have a much higher power capability for a given volume than linear amplifiers. They are also less expensive.

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. They typically remain in an on-state without interruptions for periods of approximately 30 minutes or longer

Autoclaves are used for applications requiring constant pressure and temperature for long periods of time.  Common applications include the sterilization of instruments and polymerization of rubbers and plastics

Thermal cyclers are laboratory instruments capable of generating and maintaining specific temperatures for a defined period of time

Sample-and-hold amplifiers freeze analog voltage instantly. During this process the HOLD command is issued and analog voltage is available for an extended period

Transient voltage suppressor (TVS) diodes are designed to limit over-voltages. They can dissipate high amounts of transient power in a short period of time
