The Isotech Isis dry block calibrator from Zedflo offers operation to temperatures as low as -100°C. It enables users to calibrate temperature sensors such as RTDs, thermocouples and thermistors at low temperatures without the need for a liquid bath.
The Isis requires no hazardous fluids, unlike liquid baths, and offers flexibility and portability. It is suitable for calibration engineers working on-site with low-temperature freezers, such as those in pharmaceutical, aeronautical and food environments. Its minimum operating temperature is also lower than stirred liquid calibration baths.
The maximum operating temperature is 40°C, which is a little higher than the minimum operating temperature of Isotech Hot Blocks. Users can therefore cover temperatures -100 to 650°C or higher with two Isotech blocks.
The Isis has a large insert of 35 x 160 mm, allowing calibration of multiple sensors. For thermal validation applications, an insert with pockets for a reference probe (6.5 mm) and 20 x 3.5 mm pockets for thermocouples is available. This allows a single calibration cycle to validate up to 20 probes at a time.
Full support is available, with options for UKAS/ILAC/NATA calibration. A tutorial on calibration uncertainties and a range of supporting reference thermometers, indicators and software are also available.
