Medusa 510 Dryblock Temperature Calibrator. Temperature range 30°C to 550°C
Medusa 511 Dryblock Temperature Calibrator. 50°C to 700°C
Medusa Fixed-Point Cell and Dry block Temperature Calibrator Ambient to 700ºC
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.

• High Capacity Deep Block -- 1.75” 
  diameter x 11.25” deep (45mm Ø x 285mm)

• Use for Comparison and Fixed-Point 
  Calibration

• Use With Very Long Thermometers

For Comparison Calibration the Medusa should be used with an insert, the standard insert has 
six 0.3” pockets 9.8” deep (8mm x 250mm). Also available is an insert 1.7” in diameter x 6.7” deep (44mm Ø x 170mm) which is suspended from the top of the block so that the height is user adjustable. 
For flexibility the Medusa can also be used with accessories for infrared thermometers and surface sensors. The Medusa is available in both the BASIC (B) and the SITE (S) models.

Includes as standard: Windows Software, Computer Interface and a Ramp to Set Point Feature. Increased resolution of ±0.01 available throughout the range via the PC interface and 
from -19.99 to +99.99 locally on the auto-ranging display. 
The controller features multi-point block to display correction giving excellent absolute accuracy.
The SITE model has a universal sensor input allowing Platinum Resistance Thermometers, Thermocouples (Types K, N, R, S, L, B, PL2, T, J and E) along with Linear Process Inputs including 4-20mA current transmitters to be displayed on the indicator. 
The indicator can be programmed with up to five calibration points to provide high accuracy digital probe matching. 
The indicator and controller are both addressable over the communications link.
