SRXとシリーズは、費用対効果の高い、安定した、実験室または携帯用の耐性基準です。 SRXシリーズは、耐久性に優れ、小型で温度係数が小さいため、18°C〜28°Cの温度範囲で実験室環境以外のアプリケーションに最適です。低い温度係数のために、それらは油または温度浴を必要としない。バインディングポストは、低温EMF材料で構成されています。
SRXシリーズの抵抗規格は、1mΩ〜100MΩの範囲の値で利用可能であり、任意の要件を満たすために使用できます。高抵抗の場合、SRCシリーズの抵抗規格は190MΩ〜10TΩの範囲で使用でき、カスタム値利用可能です。
SRX / SRXの耐性基準を無期限に維持することは可能です。閉じた、頑丈な設計と密封された抵抗のために信頼性があります。このユニットは、金属製の筐体のため電磁妨害(EMI)に強いです。

The SRX and Series are cost effective, stable, laboratory or portable resistance standards. Their ruggedness and small size plus their low temperature coefficient makes the SRX Series 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.
The SRX series resistance standards are available in values ranging from 1 mΩ to 100 MΩ, with custom values available, to satisfy any requirement 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 SRX/SRX 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.
