High-Temperature Method 5 Probes

Alloy 253 High-Temperature Method 5 Probes

Our Custom Alloy Method 5 Probes are designed for hot corrosive gases. Alloy probes are built to order from a choice of alloy materials dependant on availability. The 3/8-inch pitot, 1/4-inch stainless steel quick connects, stack temperature thermocouple with magnesium oxide insulation, and orsat lines are secured to the sheath, but are designed to allow for differences in thermal expansion rates. The pitot is made of one-piece construction as modular tips are not recommended in high-temperature applications. Order liners separately.

– Recommended for high-temperature applications
– Highly corrosion-resistant

Call for current pricing and alloy availability.

Additional options such as 3/8-inch quick connects are available upon request.

For custom probe configurations, use the Part Number Configuration Legend and have your custom part number ready when you contact an Apex Instruments sales representative.

Air-Cooled High-Temperature Method 5 Probes

Air-cooled Method 5 Probes up to 8 feet in length, applicable for high-temperature sources. Concentric tubular design allows the cooling air to return and exhaust out of the stack. A variable-speed high-capacity blower is needed for cooling.

Order blower separately.
Order probe heater separately, if necessary.
