Digital video recorders record and store video camera output in digital form on disk

Chart recorders and strip charts are data acquisition tools used to generate a plot, graph or other visualization of data versus time

Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms

Audio recorders / voice loggers are used to locate, retrieve, duplicate and/or distribute audio voice or data information from single system environments to large multi-channel networked systems

Video cassette recorders (VCRs) receive video input and capture data onto analog or digital videotape. Consumer-grade products are not included in this category

Fault detectors and recorders are electric power instruments that detect and/or record electrical faults that may happen in power lines. A fault recorder keeps a log about the time, location, intensity of the fault

Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.

KVA meters measure the apparent power of AC devices in kilovolt-amperes (KVA). Apparent power is the combination of a circuit’s true power and reactive power.

Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.

Paper recording charts and consumables consist of circular charts, strip charts, markers, fanfolds, sheets, pens, and pen arms used in chart and strip recording instruments.

Pressure instruments are used to measure, monitor, record, transmit or control pressure

Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input.

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments.

Digital audio systems electronically record and store audio signals such as voice, music, alarm, and security messaging for broadcast, editing, monitoring, and playback

Thermal profilers are temperature instruments or recorders that provide temperature profiles for furnaces, kilns, or other continuous thermal processes
