<h2>Introduction</h2>
<p>Deciding which thermocouple probe to use for your application can be a daunting task. There are multiple types of probe designs, each with its specific uses and advantages. This article will guide you on selecting the right thermocouple probe for your temperature sensing needs by looking at various factors such as temperature range, environment, accuracy, and cost.</p>
<div class="section">
<h2>Types of Thermocouple Probes</h2>
<h2 class="highlight">K-type</h2>
<p>The K-type thermocouple probe is the most widely used and cost-effective option. It has a temperature range of -200°C to 1250°C and offers good accuracy, making it suitable for a broad spectrum of applications.</p>
<h2 class="highlight">J-type</h2>
<p>The J-type probe offers a narrower temperature range (-40°C to 750°C) compared to the K-type but is suited for oxidation-resistant environments.</p>
<h2 class="highlight">T-type</h2>
<p>The T-type thermocouple offers precision in low-temperature measurements, -250°C to 350°C, making it ideal for refrigeration applications.</p>
<h2 class="highlight">E-type</h2>
<p>E-type probes are made from a high-temperature-resistant metal and can measure temperatures up to 900°C.</p>
