Isothermal Technology (Isotech) 1200S Calibration Furnace


High temperature calibrator, 150 to 1200°C (2192°F)



The Isotech Pegasus 1200 calibrator is a tube furnace, which includes a specially-profiled heater that gives a central zone of constant temperature. The Isotech Pegasus 1200 calibrator 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 provide users of the Isotech Pegasus 1200 calibrator with optimal control and accuracy throughout the full range of the unit. Available in Site or Basic models, the Basic model of the Isotech Pegasus 1200 calibrator utilizes a high accuracy, high stability temperature controller which sets and indicates 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 Isotech Pegasus 1200 calibrator’s reference system to be housed in one convenient case. The temperature range of the Isotech Pegasus 1200 calibrator is 150 to 1200°C. With a stabilization time of 15 minutes, the Isotech Pegasus 1200 calibrator’s insert dimensions are 4 holes 5/16″ ø 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 Isotech Pegasus 1200 calibrator in about 25% of the normal time. All models of the Isotech Pegasus 1200 calibrator are supplied with RS232 or RS422 communications and software.
