Our product line consists of three DC voltage references and two DMM testers
VREF-01, Precision Voltage Reference
This .01% DC voltage reference is a small, low cost unit that is powered by a 9V battery. 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V units are available.
PentaRef, 5 selectable DC reference voltages
The PentaRef provides 5 different DC voltages of your choice between 0.1V and 10V - you choose the voltages to suit your needs.
Vref5-002, Precision Voltage Reference
This .002% DC voltage reference is AC line powered and only available with a 5V output.
DMMCheck, DMM Tester
The DMMCheck combines a precision 5V DC voltage reference, a precision 1.000mA DC current source, and three 0.1%, 25ppm resistors.
DMMCHECK Plus, DMM Tester
DMMCheck Plus offers all DMMCheck features plus 5VAC voltage and 1mA AC current reference sources, four 0.1%, 10ppm/ºC resistors, and 100Hz 50% duty cycle signal source standard or optionally choose any two frequencies between 25Hz and 20KHz. Can be ordered with or without an enclosure.
