Dual Furnace Models M17705, N17706 & 17707 Iss.09 – 12/14
Optional equipment includes an equalising block that fits in the heat-pipe so that the furnace can be used as a
gradient-free comparison facility. Please note that the temperature-equalising block is for use up to 700°C only.
Above 700°C the sensors to be calibrated may be immersed directly into the heat-pipe without using an equalising
block.
IMPORTANT NOTE: Since the calibration of sensors at high temperatures can be fraught with difficulties, if any
doubt exists, please consult Isotech for advice before embarking on any exercise in which there is a risk of
contamination of the sensors you are trying to calibrate.
