Resistance Substituters IET manufactures a variety of RTD simulators for the field, the laboratory or automated stations. For
high performance consider the RTD series; for programmable and lower cost consider the PRTD or OS
series; and for good performance lost cost consider the RS-RTD. All our RTD simulators use physical
"real" resistors.
Temperature/Resistance Translation Tables.
SRAC Standard Resistors Designed for Use At AC
Precision ac/dc resistance standards designed for use up to 10 kHz Available for values from 1 mΩ - 10 MΩ, Contact IET for custom values Very stable <20 ppm/year for most values at ac and dc Calibrated at dc and 1 kHz
esi SR1 Calibration Resistor
New Design, with improved specifications Versatile working calibration resistor Laboratory standard of high accuracy and stability Adjusted to within 20 ppm of nominal 50 ppm long-term accuracy for most values
DCCS DC Current Shunt Series
