Can we use the MAX 5 on a high temperature sample gas (more than 50 degrees C)?
The recommended 0-50 degrees C is the temperature range for the sample when it reaches the sensor. However the MAX5 is designed for use in much higher temperatures, like stacks and boilers. The high temperature sample will have cooled to the 0-50 degrees range by the time the it reaches the analyzer/sensors. The metal tube of the MAX5 probe is inserted into the hot sample, and the sample is cooled as it travels through the metal probe and the 15 feet of hose that is a part of the probe/thermocouple assembly. The standard MAX5 uses the probe with type K thermocouple which operates in temp 0-1200 deg. C. We also have the low temp. option which is built with the type J thermocouple 0-750 deg C.
