The Isotech Drago 4934 temperature calibrator provides an adjustable isothermal enclosure for calibration purposes. It is part of the award winning Isocal-6
family and with a reference probe can be used with different accessories for Dry Block, Infrared, Surface Calibration and even with ITS-90 Fixed Point Cells
for uncertainties to 0.001°C. In Dry Block Mode, the large 65mm diameter block allows for the calibration of either larger probes or for calibrating many
sensors simultaneously.
