To calibrate temperature sensors to 250°C look no further than Isotech’s portable stirred liquid baths. The Hyperion calibrates from 45°C below ambient to 140°C and the Drago from 30 to 250°C. The large calibration volume is more than twice the size of alternative products. The useable area is a full 65mm diameter with a depth of 160mm, the overall well depth of 190mm allows room for space at the top and the bottom magnetic stirrer.

Stirred liquid baths are suitable for temperature sensors of all types, shapes and sizes. Accuracies are much greater than those from Dry Blocks alone and with suitable reference thermometers performance of up to 0.005°C is achievable.

The Hyperion is available in two models. If the liquid is directly in the block then the controller only model, or Basic (B) model, can be selected. This model is also suitable where an external indicator and standard will be used. Alternatively the site model (S) includes a built in temperature indicator for high accuracy or for best accuracy an external indicator can be used, an ideal combination is a TTI model and a 935-14-16
Standard Probe, see Indicators, Probes and Accessories section. The S model can be provided with UKAS certification.

The Hyperion can also be used with the supplied Cal NotePad software to automatically calibrate thermostats. When using a separate indicator and probe then different accessories can be added for Dry Block, Blackbody, Surface Sensor, Liquid Containers and even ITS-90 fixed point operation.
