Type K thermocouple

Type K (chromel {90% nickel and 10% chromium}alumel {95% nickel, 2% manganese, 2% aluminium and 1% silicon}) is the most common general purpose thermocouple with a sensitivity of approximately 41 V/C, chromel positive relative to alumel. It is inexpensive, and a wide variety of probes are available in its −200C to +1250C / -328F to + 2282F range. Type K was specified at a time when metallurgy was less advanced than it is today, and consequently characteristics may vary considerably between samples. One of the constituent metals, nickel, is magnetic; a characteristic of thermocouples made with magnetic material is that they undergo a deviation in output when the material reaches its Curie point; this occurs for type K thermocouples at around 350C / 662F.
