High-Temperature Method 5 Probes

Alloy 253 High-Temperature Method 5 Probes

Our High-Temperature Alloy Method 5 Probes are designed for hot & corrosive gases and built to order. Call for current pricing and alloy availability.

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

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.

Heaters, liners, and modular pitot tips are sold separately. Zone heating is necessary if a heater is purchased with this probe sheath. The amount of zone heating required differs based on specific testing needs.

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

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.
