Medusa 510 calibrates temperature probes from 30°C to 550°C, in three zone control of the substantially large calibration volume, 45 mm diameter by 285 mm deep. It can be used as a dry block, a liquid bath, as a blackbody source and as an ITS-90 fixed point system with calibration uncertainties as small as 0.001°C`.
In addition to the main heating zone, there are additional top and bottom heaters which compensate for the end losses creating a constant temperature zone across the well.
For comparison calibration, Medusa 510 should be used with an insert, the standard one has six 8 mm holes of 250 mm deep. Also available is an insert of 44 mm diameter x 170 mm deep which is suspended from the top of the block so that the height is user adjustable.
Medusa 510 is available in two models, the BASIC (B) and the SITE (S).
The B model includes a sophisticated temperature controller with a dual display for set temperature and dry block temperature.
The S model additionally includes an in-built temperature digital indicator to which an external temperature sensor can be connected, giving greater accuracy eliminating temperature gradient and loading errors. The S model has 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 to be displayed on the inbuilt 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.
Also included in the Site model is a timer which can set the bath between two temperatures, and automate ITS-90 fixed point operation.
For surface sensor and Blackbody use, an external thermometer is recommended.
For laboratory accuracy, Medusa 510 can be used with high-end temperature indicator.
