The Model 6221 is the only AC current source on the market. Until now, researchers and engineers have been forced to build their own AC current sources. The Model 6221 provides better accuracy, consistency, reliability, robustness, and cost effectiveness than "home-made" solutions. (read more)

DT-3343T/3345/3347 series professional True RMS clamp meters provide accurate AC, AC/DC current and voltage readings regardless of waveforms. These meters can be used in most industrial and commercial applications where non-linear loads distort the current or voltage waveform. (read more)

The FC-31/32/33/35 series are designed to verify the presence of load current, non-contact voltage and flashlight etc. The small bodies and jaws fit perfectly in your hand and a large backlit display is easy to read. (read more)

DT-337 is designed to verify the presence of load current, voltage and resistance etc. The small body and clamp jaw fit perfectly in your hand. (read more)

The Columbia AC/DC Clamp-On Tong Test Ammeters (now manufactured by Weschler Instruments) measure AC or DC current instantly and accurately simply by encircling the conductor with the jaws and closing them. A clear accurate reading instantly registers on the scale. (read more)

The QuadProcess and OctProcess data loggers provide a convenient way to capture and record 4-20 mA current loop data or other current values up to +/- 100 mA. They offer sample rates from once a second to twice a day, storage for up to 32,000 readings per channel and scaling to engineering units. (read more)

AC-DC or DC-DC • Single, dual, and triple output • With Screw Terminals or PC Board Mounting • Shipped within 3 Days • 1 Year Warranty (read more)

Compare the DC input to a fixed or adjustable current threshold. The output is an isolated switch or relay that activates as required. DC current detectors are suited for ground fault current monitoring. (read more)

Monitor DC current by providing a magnetically isolated analog output that is directly proportional to the input. Low current ranges are available for differential (ground fault) current monitoring. (read more)
