Dry Block Calibrator | Low Temperature

Supplier: Zedflo Australia

The ISOTECH Isis Dry Block Calibrator from Zedflo, offers operation to temperatures as low as -100°C, and is the first dry block bath working to such a low temperatures.

Price Guide: POA

With the Isis dry block calibrator, it is now possible to calibrate temperature sensors such as RTDs, thermocouples and thermistors at ultra-low temperatures, without the need for a liquid bath.

Unlike liquid baths, the Isis requires no costly or hazardous fluids and offers much greater portability and flexibility. This will be of particular value to 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 (and costs) 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°C to 650°C or higher with just two Isotech blocks.

The Isis has a large insert: 35mm diameter by 160mm deep. This allows for calibration of multiple sensors. For thermal validation applications, there is also 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.

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 is also available.

The Isis forms part of a wide range of temperature calibrators, dry blocks and temperature baths provided by Zedflo.
