<h2>Overview</h2>
<p>The Tempco TCP90088-J thermocouple is a precision temperature sensor engineered for industrial and commercial applications requiring accurate, continuous monitoring. This Type J thermocouple features a 48-inch fiberglass-insulated lead that provides flexibility in probe positioning and extends sensing reach to remote monitoring points. The grounded junction design and 304 stainless steel sheath deliver fast thermal response and corrosion resistance.</p>
