Triple Point of Water Maintenance Apparatus
The GD-1020S water triple-point freezing and realization apparatus accommodates three water triple-point cells simultaneously for uncertainty comparison. It features a temperature control stability of ±0.001°C per 10 minutes and a temperature uniformity of 0.002°C within the bath, providing an optimal environment for long-term reproducibility. The bath has a diameter of 200 mm and a depth of 520 mm. The design incorporates rapid cooling capabilities and operates with an exceptionally low noise level, ensuring a quiet laboratory environment. This unit is an essential piece of equipment for any temperature laboratory.
