The Annealing Furnace, model 414, is designed to heat, anneal and cool Standard Platinum Resistance Thermometers (SPRTs) prior to calibration. The temperature range of the Furnace, from ambient to 1000°C, enables all types of SPRTs to be annealed.

Whilst heat pipe furnaces offer the ideal environment to melt and freeze ITS-90 Fixed Points the temperature range is limited by fluid that flows inside the pipe. Three zone furnaces can offer wider operating ranges and still meet the requirements for “Optimal Realization of the Defining Points of the ITS-90…” CCT/2000-13. In place of a heat pipe the 17703 Medium Temperature furnace uses top and bottom guard heaters to minimise temperature gradients.

Are you fed up with cold wet hands, and hours of frustration when you produce an ice mantle in your Triple Point Cell?

This dedicated apparatus has more than 35 years of proven use and is widely used by the worlds’ leading NMIs. In a recent International study cells from 21 of the world’s leading laboratories were inter-compared; the study used two Isotech 18233 Baths to maintain the cells during the inter-comparisons.
