6636 Series Temperature Stabilized Resistance Standards

• Temperature Coefficients as low as ± 0.2 ppm/°C
• Stabilities as low as < 6 ppm/year
• Eliminates Air and Oil Bath Requirements
• Resistance Range: 10 MΩ to 100 TΩ In Single Decade Increments
• Temperature Regulation: ± 0.01 °C Over a 1 Year Period
• Custom Values / Models Available

• Guildline Instruments 6636 Series is a modular series of Temperature Stabilized Resistance Standards that can be rack mounted or simply set on a bench. The 6636 Series provides a logical extension to the popular 6634A series of Temperature Stabilized Resistance Standards. The 6636 can be configured with up to 6 standard decade resistance values available covering the range of 10 MΩ to 100 TΩ. Each resistance element is isolated and has an N-type terminal connection at the back panel. Special resistance and decade values are available in the range of 10 MΩ to 100 TΩ. All models purchased with less than 6 resistance standards can be expanded at any time with a factory upgrade. High and Ultra High Resistance Standards have inherently large temperature coefficients associated with them, the effect of which is greatly reduced by placing them in a 30 °C temperature stabilized chamber. Chamber temperature set points of 35 °C and 40 °C are available on request
