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
Search by Specification | Learn MoreRefractories and high temperature insulation include many different types of ceramic insulation, refractory shapes, and refractory cements.
Search by Specification | Learn MoreSpectrum 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
Search by Specification | Learn MoreDigital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements
Search by Specification | Learn MoreSeismic instruments are used to measure low frequency ground motion caused by earthquakes.
Learn MoreContinuous 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
Search by Specification | Learn MoreAutoclaves 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
Search by Specification | Learn MoreThermal cyclers are laboratory instruments capable of generating and maintaining specific temperatures for a defined period of time
Search by Specification | Learn MoreSample-and-hold amplifiers freeze analog voltage instantly. During this process the HOLD command is issued and analog voltage is available for an extended period
Search by Specification | Learn MoreTransient voltage suppressor (TVS) diodes are designed to limit over-voltages. They can dissipate high amounts of transient power in a short period of time
Search by Specification | Learn MoreFrequency counters are digital indicating meters for accurate measurement and display of square wave and pulse input signals.
Learn MoreRefractory services for manufacturing, installing and repairing refractory shapes or monolithic refractories.
Search by Specification | Learn MoreAnalog multimeters are instruments that are used to measure electrical quantities such as voltage, current, resistance, frequency and signal power
Search by Specification | Learn MoreTLD (Thermoluminescent dosimeters) and film badges are used to detect radiation at levels that can be harmful to humans.

The SnapShock® 4000 is a compact, battery powered, single axis peak acceleration, date, and time recorder. The instrument measures and records the peak acceleration (shock or vibration) levels to which it is exposed, along with their date and times of occurrence. (read more)
Phase masks are traditionally surface relief gratings etched in fused silica for use in the ultra-violet range (193 nm to ~ 400 nm). Because of etching limitations during fabrication, the ratio of grating period divided by the illuminating light wavelength is limited to values greater than 1. (read more)
The EP1217 / EP1227 family of solid state motor timers are command systems which employ a conformal coated, open panel circuit board assembly. The controls include a digital timer circuit and integral air switch mounted to a double-sided fiberglass printed circuit board. (read more)
