The Isotech Isis dry block temperature calibrator offers stable temperatures as low as -100°C making it the only dry block calibrator capable of reaching such low temperatures. With the Isis, it is now possible to calibrate temperature sensors such as PRTs, thermocouples and thermistors at ultra low temperatures without the need for a liquid bath.
Unlike a liquid bath, the Isis requires no costly or hazardous fluids while offering greater portability. This will be of particular value to calibration engineers working on-site with low temperature freezers such as those found in pharmaceutical, aeronautical and food preparation environments. The Isis also produces lower temperatures than most stirred liquid calibration baths making it an attractive alternative in laboratories.
Isotech Isis dry block calibrators have a maximum operating temperature of 40°C, a little higher than the minimum operating temperature of Isotech Hot Blocks. This permits covering the range from -100°C to 650°C or higher with just two Isotech blocks. By limiting the maximum temperature the reliability and operating life of the massive 80 Watt Free Piston Stirling Cooler (FPSC) is maximized.
The Isotech Isis was designed for reliability. Even after 20,000 hours of use (nominally equivalent to 10 years at 40 hours use each week) reaching -100°C is still possible, with an increase in cooling time of less than 10%. The Isis also provides outstanding accuracy, stability and uniformity.
The Isis utilizes large, 35 by 160mm inserts which allows for calibration of multiple sensors. For thermal validation applications there is an insert with pockets for a reference probe (6.5mm) and 20 x 3.5mm pockets for thermocouples. This allows a single calibration cycle to validate up to 20 probes at a time.
