510 Medusa and 511 Medusa Dry block Calibrator.
510 Medusa Dry block Temperature Calibrator. Temperature range 30°C to 550°C
511
Medusa 3 Dry block Temperature Calibrator. 50°C to 700°C
Medusa Fixed-Point Cell and Dry block Temperature Calibrator Ambient to 700°C.
A wide range of Dry blocks to suit probes requiring a large immersion depth are available.
These products feature large and deep calibration volumes. As such they are less portable then the earlier.
Dry Blocks in this book but have higher capacities and retain outstanding temperature uniformity,
this uniformity is so good that these larger products are most suitable as apparatus for Secondary
Laboratories to realize the Fixed Points of ITS-90.
Medusa Dry block calibrator.
