Designed for long term use where economy is a factor, NHXH ceramic connectors are ideal for high temperature applications. NHXH connectors are permanently dot coded to conform to ANSI and OMEGA standards; for applications such as high vacuum furnaces where contamination would adversely affect the process. Temperature is limited only by the hardware. Chromega-Alomega, Iron-Constantan and Chromega-Constantan can be used at temperatures up to 1200deg F(650deg C) and Copper-Constantan can be used accurately over its entire calibration range of 750deg F(390deg C).No damage will be done by exposure to higher temperatures, but accuracies may exceed limits of error if a temperature gradient exists across the connector.
