K-Type Thermocouple | High Temperature Sensor | Stainless Steel Needle Probe

This K type thermocouple measures temperatures from -200°C to 1250°C. Its stainless steel needle probe reaches into equipment. The shielded wire keeps the signal clean. This is a standard K type sensor for industrial and lab work. Features and Benefits - Measures from -200°C to 1250°C - Use it for very cold monitoring or checking furnace temperatures. - Probe lengths from 50mm to 300mm - Pick the size that fits your machine or kiln. - Metal-braided wire up to 5m - This protects the signal from electrical noise, giving you stable readings. - Chromel-alumel construction - This is the standard for K-type sensors, giving consistent results for general use. Applications - Industrial Processes - Good for furnace temperature measurement, chemical processing, and monitoring plastic injection molding machines. - Workshop and Lab Use - Use this K type probe for a pottery kiln, a heat-treating oven, or experiments needing exact heat data. - HVAC and Automotive - Check exhaust gas temperatures, fix industrial heaters, or diagnose high-temperature issues in engines and machinery. What It Is This is a K-Type thermocouple, designed as a high-temperature sensor. It features a durable stainless steel needle probe. The sensor is manufactured by SNDHEATER and comes with a shielding wire for reliable performance. Available with various probe lengths, from 50 mm to 300 mm, and wire lengths ranging from 1 m to 5 m, it offers flexibility for diverse applications. It operates within a voltage range of 20-50 V. Key Uses & Applications The K-Type thermocouple is ideal for accurate temperature measurement in high-temperature environments. Its stainless steel needle probe makes it suitable for insertion into various materials, liquids, or gases. Common applications include monitoring temperatures in industrial processes, ovens, furnaces, and laboratory settings. While this specific model is a general high-temperature sensor, thermocouples are often used in appliances such as water heaters to sense pilot light presence or in gas fireplaces to ensure safe operation. How to Choose When selecting this K-Type thermocouple, consider the required probe length and wire length. Probe lengths are available at 50 mm, 100 mm, 150 mm, 200 mm, and 300 mm. Wire lengths come in 1 m, 2 m, 3 m, 4 m, and 5 m. The chosen length should accommodate the depth of measurement needed and the distance to your display gauge or temperature controller. All options feature a stainless steel needle probe and shielding wire for protection. Grit / Spec Guide This K-Type thermocouple features a stainless steel needle probe. It operates within a voltage range of 20-50 V. The probe is available in five lengths: 50 mm, 100 mm, 150 mm, 200 mm, and 300 mm. The shielding wire lead comes in lengths of 1 m, 2 m, 3 m, 4 m, and 5 m. Ensure the chosen probe length is appropriate for the measurement depth. The shielding wire helps protect the lead from interference and damage in demanding environments. Care & Safety To maintain the K-Type thermocouple, regularly inspect the stainless steel probe and the shielding wire for any signs of damage or wear. For general cleaning, wipe the probe with a dry, clean cloth. Avoid harsh chemicals that could corrode the stainless steel. If using in a water heater, a thermocouple typically does not require cleaning; if faulty, it is usually replaced. Similarly, for a gas fireplace, if a thermocouple is malfunctioning, replacement is the standard procedure rather than cleaning. Always ensure the voltage supply is within the 20-50 V range.
