Laurel Electronics, Inc. products

Laureate™ DC voltage meters and DC current meters are DC digital panel meters with a DC signal conditioner board. They combine high accuracy with high read rate and a wide range of isolated output options for computer interface and control. DC meter accuracy is 99.99% of full scale ±2 counts. DC voltmeter operation (selected by jumpers) provides and six full-scale DC voltage ranges from ±200.00 mV with 10 mV resolution to ±600.0V with 100 mV resolution. The 200.00 mV and 2.0000V ranges provide a high input impedance of 1 Gohm to minimize the load on the voltage signal. DC ammeter operation (selected by jumpers) provides four full-scale DC current ranges from ±2.0000 mA with 0.1 mA resolution to ±5.000 A with 1 mA resolution. The 5.000 A range measures the IR drop across a built-in 10 milliohm current shunt.

The Laureate™ True RMS meter is a 60,000 count digital panel meter with exceptional performance at half the price of a bench top meter. It can measure true RMS voltage or current of AC signals where there is considerable distortion of the waveform, such as rectifier outputs or waveforms chopped by an SCR, TRIAC or transistor circuit, as illustrated. Laureate™ True RMS AC Voltage & Current Meter, 1 Cycle Update at 50/60 Hz. 200 mV - 600 V and 2 mA - 5 A full-scale ranges.
