Zedflo Isotech Isis Dry Block Calibrator

Friday, 08 June, 2012 | Supplied by: Zedflo Australia


The Isotech Isis Dry Block Calibrator, from Zedflo, offers operation to temperatures as low as -100°C and is claimed to be the only block bath working to such a low temperature. It is now possible to calibrate temperature sensors such as RTDs, thermocouples and thermistors at ultralow temperatures, without the need for a liquid bath.

Unlike liquid baths, the product requires no costly or hazardous fluids and offers greater portability and flexibility. This makes it suitable for calibration engineers working on site with low-temperature freezers as encountered in pharmaceutical, aeronautical and food environments.

The minimum operating temperature is lower than stirred liquid calibration baths and users in laboratories can also benefit by avoiding the ongoing need for expensive fluids. The maximum operating temperature is 40°C, a little higher than the minimum operating temperature of Isotech Hot Blocks. This permits covering temperature ranges from -100 to 650°C or higher with just two Isotech blocks.

The device has a large insert: 35 mm diameter by 160 mm deep. This allows for calibration of multiple sensors. For thermal validation applications, there is also an insert with pockets for a reference probe (6.5 mm) and 20 x 3.5 mm pockets for thermocouples. 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 getting the best calibration uncertainties and a full range of supporting reference thermometers, indicators and software are also available.
