ISOCAL 6 Calibrators (Large Volume) -50°C to 250°C (482°F)
Available in Drago and Hyperion Models
• 2.5" (65mm) Diameter Calibration Volume
• Portable Liquid Bath for high accuracy calibration of awkward shaped sensors
• Convertible for Dry Block Operation and more
• Calibrates All Sensor Types
• Windows Software and PC Interface
• Available in the Hyperion 936 and Drago 394 Models
Detailed Description
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 (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. An ideal combination is the TTI-6 and 935-14-16 Probe which can be programmed with up to five calibration points to provide high accuracy digital probe matching.
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. |

Display to Block Accuracy Better than ±3°C
Detailed Description
The Pegasus 1200 is a tube furnace, which includes a specially-profiled heater that gives a central zone of constant temperature. It is ideal for the calibration of noble metal thermocouples, type R and S, in industries such as glass making, electrical power, automotive and material processing. A state of the art digital controller with custom tuning and 5 discrete calibration points provides optimal control and accuracy throughout the full range of the unit.
Available in Site or Basic models, the Basic models utilize a high accuracy, high stability temperature controller which sets and gives an indication of the block temperature. A standard temperature sensor and external thermometer should be used to measure the block's temperature, and industrial sensor outputs are compared to known and traceable values. The site models include an independent temperature indicator that may connect to an optional type R or type S thermocouple or PT100 standard probe, allowing the reference system to be housed in one convenient case.
The Pegasus 1200's temperature range is 150°C to 1200°C. Its stabilization time is 15 minutes. The insert dimensions are: 4 holes 5/16" x 3.2" deep (8mm x 80mm) and the insert options allow drillings to be made per customer specifications.
A fast cool down probe is available as an option. When connected to an air supply, this probe cools down the Pegasus 1200 in about 25% of the normal time. All Pegasus 1200 Models are supplied with RS232 or RS422 communications, and software. |
