Dissipation at rated excitation (typical)>7.5-8 W at 4.2 K
Magnetic fieldsNot recommended
RadiationNot recommended

1Short-term reproducibility data is obtained by subjecting sensor to repeated thermal shocks from 305 K to 4.2 K. 
2Recommended excitation for T < 1 K based on Lake Shore calibration procedures using a 372 AC resistance bridge temperature controller. 

Calibration accuracies3 

5 mK±1.2 mK
7 mK±0.8 mK
10 mK±1 mK
20 mK±2 mK
50 mK±4 mK
1.4 K±16 mK
4.2 K±16 mK
10 K±30 mK

3[(Calibration uncertainty)2 + (reproducibility)2] 0.5 Rated accuracies are dependent on following proper cool-down and sensor installation.
