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
RS Series Resistance Substitution Box
Accurate 0.1% to 1% Wide range from 0.01 Ω - 100 MΩ (Depending on Model) Broad choice of standard and optional models with many powerful features Compact, convenient, and rugged
HARS Series Resistance Decade Box
