Products & Services
Power Quality Analyzers and Monitors
Power quality analyzers measure and monitor electrical power parameters to avoid disturbances, track steady-state variations, and ensure the reliability of power distribution systems.
Digital Pressure Gauges
Digital pressure gauges use electronic components to convert applied pressure into usable signals. The gauge readout has a digital numerical display.
Purge Controllers and Indicators
Purge controllers and purge indicators are used to regulate and monitor hazardous environments within enclosures.
Pressure Transmitters
Pressure transmitters translate the low level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed. These devices include pressure sensors, transducers, elements, and instruments.
