SRX/SRC Series Economical Resistance Standard

 

SRX/SRC Series Economical Resistance Standard

 

Wide range of values - 1 mΩ to 10 TΩ

Very stable - up to 10 ppm/yr

 ISO-17025 Accredited Calibration Included

 3 Year Warranty Included

 Excellent TC - as low as 1 ppm/°C

 

 Excellent choice for a resistance standard to calibrate DMM's, Micro-Ohmmeters and megOhmmeters

In addition to the standard values, any custom value is available.  Please contact the IET sales department, for more information

    Combination of multiple resistors in a single housing is available

 

 

The SRX and SRC Series are cost effective, stable, laboratory or portable resistance standards. Their ruggedness and small size plus their low temperature coefficient makes the SRX and Series Resistance Standard ideal for any applications outside of laboratory environment within the tem­perature range of 18°C to 28°C. Because of the low temperature coefficient, they require no oil-or-temperature bath. The binding posts are constructed of low-thermal emf material.

 

For lower resistances, the SRX series resistance standards are available in values ranging from 1 mΩ to 100 MΩ, with custom values available.

 

For higher resistances, the SRC series resistance standards are available in values ranging from 190 MΩ to 10 TΩ, with custom values available.

 

It is possible to maintain the SRX & SRC resistance standards indefinitely. They are reliable due to their closed, rugged design and sealed resistors. The units are resistant to electro­magnetic interference (EMI) because of their metal enclosure.

 

Specifications

 

SRC Series Maximum Voltage: 5000 V.

Test Conditions: Four-terminal Kelvin measurements, low power, at 23°C; two-terminal for 1 MΩ and over. Initial calibration data traceable to NIST is provided.

Terminals: SRX: Four 5-way binding posts for 4-terminal measurement for 190 kΩ and under; two binding posts for 1 MΩ and over.
