Gallium Cell Provides Temperature Accuracy
June 4, 2001
Model 5943 from Hart Scientific is designed for fixed-point thermometer calibrations. The stainless steel gallium cell achieves 29.7646oC with uncertainty of 0.00008oC and reproducibility of 0.000025oC. The gallium is sealed in a Teflon envelope, which is sealed in stainless steel. Realization and maintenance of melting plateaus are automated through the company's gallium maintenance system. Users need only initiate the melt routine through the front panel control buttons and insert an automated inner melt heater into the cell.
