Product Description
Kaye K150-4C Ice Point Reference – Precision Thermocouple Calibration Standard, 4 Channels, NSN Registered
This used Kaye K150-4C is a precision ice point reference standard designed for accurate thermocouple calibration and cold junction compensation. The K150-4C maintains 4 individual reference thermocouple junctions at exactly 32°F (0°C) in an internal sealed test well, supporting thermocouple types J, K, T, and E .
Kaye Instruments (now part of Amphenol) has been a global leader in thermocouple reference systems for over 65 years, with their Ice Point References considered the gold standard for precision temperature measurement . This unit carries NSN 6685-00-005-1288, confirming its use in military and defense applications where strict traceability and quality standards apply .

Historical & Technical Context
Kaye Instruments pioneered the Ice Point Reference in the 1960s, and these instruments remain the industry standard for precision cold junction compensation . The K150 series features built-in thermocouples terminated at matching material posts, making it ideal for applications where frequent connections are made or when calibrating temperature instruments .
The K150-4C specifically provides accurate simultaneous reference for thermocouple sensors with 4 channels of built-in reference junctions . Its NSN registration (6685-00-005-1288) confirms its acceptance in military and federal applications, with part numbers cross-referenced across multiple defense supply systems .
