Portable Liquid Calibration Baths


To calibrate temperature sensors from 45ºC below ambient to 250ºC look no further than Isotech's new portable stirred liquid baths. The useable calibration volume is 65mm diameter and the overall depth of 190mm gives more than twice the volume of alternative products.

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 0.005C is achievable.

There are two models available; 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.

The S model can be provided with UKAS certification. When using a separate indicator and probe (SITE or Stand Alone Model) then different accessories can be added for Dry Block, Blackbody, Surface Sensor, Liquid Containers and even ITS-90 fixed point operation.

Two Models
Hyperion and Drago stirred liquid baths calibrate temperature sensors from 45 deg C below ambient to 140 deg C, and from 30 to 250 deg C, respectively. Useable calibration volume is 65 mm dia and depth is 190 mm, making them suitable for temperature sensors of all types, shapes and sizes. With suitable reference thermometers, performance of 0.005 deg C is achievable. Two models are available: Basic, where external indicator is used, and Site, which has built-in indicator.


Liq BathTo 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 (284°F) and the Drago from ambient to 250°C (482°F). The useable calibration volume is a massive 2.5” (65mm) diameter and the overall depth of 7.5” (190mm) gives more than twice the volume of competitors’ products.

Stirred liquid baths are suitable for temperature sensors of all types, shapes and sizes. Stabilities 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 and the Drago are available in two models. If the liquid is directly in the block then the controller only model, or Basic (B) model, can be selected. However, instead of putting liquids directly in the block liquid containers can be used to facilitate rapid change of liquids. When using a liquid container, Dry Block Insert, Blackbody Target or the Surface Sensor Kit a separate reference thermometer should be used to compensate for the varying offset between the controller and the accessory temperature. In this case you should choose the site version (S) which includes a built-in temperature indicator for high accuracy or for best accuracy an external indicator can be used.

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, locally on the auto-ranging front display, from -19.99 to +99.99 with the Hyperion and 0.01 to +99.99 with the Drago. The controller features multi-point block to display correction giving good absolute accuracy.
