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

Current sense amplifiers are integrated circuits with operational amplifiers and sense resistors that are used in measuring the amplitude and direction of current in circuits

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

Automated test equipment (ATE) is used to monitor and control test and measurement devices, keeping human interaction at a minimum

Instrumentation amplifier chips are precision amplifier circuits with both high-impedance differential inputs and high common-mode rejection.

pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application.

Resistance standards and decade boxes provide a highly accurate standard value of resistance for calibration and testing

Calibration standards and reference sources include any source that can provide a reference for the calibration of an instrument or comparison of a material or component

Codes, standards and regulations are developed, maintained, and promoted by regulatory agencies, engineering societies, and trade organizations

Operational transconductance amplifiers (OTA) are devices that convert an input voltage to an output current. They are primarily voltage-to-current amplifiers

Capacitance standards and decades provide a highly accurate standard value of capacitance for calibration and testing

Certification services include companies that test, inspect, register and/or certify products, components, equipment, instruments, processes, management systems or facilities. This area also includes organizations that evaluate, audit, assist, train and/or register companies on facility or system wide assessments such as ISO registration, process quality audits, health and safety assessment, and management systems evaluation.    

Optical calibration standards are used to calibrate the optical properties of optical detectors and instruments

Inductance standards and decades provide highly accurate and digitally variable standard values of inductance for calibration, comparison and testing
