BASO K16RA-24 Thermocouple

The BASO K16RA-24 Thermocouple is a high-performance standing pilot ignition system component engineered for demanding thermoelectric applications. This 24-inch nickel-plated thermocouple is specifically designed to provide superior corrosion resistance, making it the preferred choice for HVAC technicians working with thermo-electric valves in environments prone to oxidation. Featuring a standard 11/32-32 male nut connector, the K16RA-24 delivers a stable 25-35 mV open circuit range, ensuring the safety pilot stays energized under consistent thermal load. Its Husky series construction is built to withstand maximum hot junction temperatures up to 1500°F (816°C), offering a reliable millivolt replacement for standard copper leads. The nickel-plated finish not only extends the service life in high-moisture or chemical-heavy applications but also maintains electrical conductivity for drop-out time efficiency. This universal-style lead is compatible with most Baso pilot burners and serves as a direct cross-reference for various 17D, 50, and K15 series units, providing the rugged durability required for industrial heating and commercial boiler maintenance.

• Corrosion Resistance: Heavy-duty nickel plating prevents premature failure in harsh combustion environments.
• High-Temperature Rating: Capable of withstanding hot junction temperatures up to 1500°F without degrading output.
• Standard Compatibility: Universal 11/32-32 male nut ensures seamless integration with most standing pilot gas valves.
• Stable Millivolt Output: Generates a reliable 25-35 mV signal to keep the electromagnetic power unit engaged.

• What is the proper millivolt reading for the K16RA-24? In an open circuit test, you should see between 25 and 35 mV. If the reading drops below 17-18 mV during a closed circuit test, the thermocouple should be replaced to prevent pilot dropout.
• Can this replace a standard copper thermocouple? Yes, the K16RA-24 is a premium nickel-plated replacement that offers better durability than standard copper, provided the 24-inch length and 11/32-32 connection match your current specs.
• What causes the tip to fail prematurely? Excessive flame impingement. The pilot flame should envelop the top 3/8" to 1/2" of the tip. A "cherry red" glow indicates the flame is too sharp and may weld the internal junction; aim for a "dull red" glow with a soft blue flame.
