Seems to be accurate. - I needed to measure a refrigerant pipe that was in an awkward spot inside a mini split outdoor unit. This was available for overnight delivery so I thought I'd give it a try. I was surprised to find that it matched my Klein clamp-on thermocouple exactly when testing the same pipe side by side. This did the job and helped me confirm there was no obstruction in the refrigerant line strainer on my unit. It now lives in my HVAC toolbox! Review: OK for the price - works well. I only wish the temperature reading would display quicker. You have to leave it there and it gradually builds up. ## Features - WHAT YOU GET: 1 x K-type surface temperature probe (model NR-81531B) with flexible spring-loaded contact tip and a standard 2-pin miniature K-type plug; plug it straight into any K-type thermometer or multimeter. - WIDE RANGE: Measures -58 deg F to 932 deg F (-50 deg C to 500 deg C), covering everyday surface testing from iced surfaces and cold storage up to griddles, soldering irons and hot metal. - FAST, CONTACT READING: The stainless steel contact tip sits flat on the surface and responds in seconds, so you get a stable reading without holding the probe against a hot pan for a long time. - WIDE COMPATIBILITY: Standard K-type output works with most K-type thermometers, multi-meters and HVAC meters; simply set your meter to the K-type / thermocouple mode before use. - BUILT FOR THE BENCH AND THE FIELD: Suited to HVAC checks, griddle and cookware surface testing, appliance repair, automotive diagnostics, electronics and lab work. NOTE: surface/contact probe only - not for measuring internal food or body temperature, and not an infrared or laser thermometer. Please confirm your meter supports K-type input. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PH2JHGT | | Additional Features | High Accuracy | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #79,100 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #106 in Temperature Probes & Sensors | | Brand | Xnrtop | | Brand Name | Xnrtop | | Color | Yellow, Silver Tone | | Connectivity Technology | Usb | | Customer Reviews | 4.0 out of 5 stars 71 Reviews | | Display Type | Analog | | Included Components | Temperature Thermocouple | | Indoor Outdoor Usage | Indoor | | Item Length | 5 inches | | Manufacturer | Xnrtop | | Model | NR-81531B | | Model Name | FGG12011 | | Outer Material | Metal, Plastic, Stainless Steel | | Part Number | FGG12011 | | Product Care Instructions | Wipe Clean | | Response Time | 500 milliseconds | | Reusability | Reusable | | Special Feature | High Accuracy | | Specification Met | CCC | | Style Name | Probe | | UPC | 712317087253 | | Unit Count | 1 Count | | Upper Temperature Range | 500 °C | ## Product Details - **Age Range (Description):** Adult - **Brand:** Xnrtop - **Connectivity Technology:** Usb - **Display Type:** Analog - **Included Components:** Temperature Thermocouple - **Outer Material:** Metal, Plastic, Stainless Steel - **Product Care Instructions:** Wipe Clean - **Special Feature:** High Accuracy - **Specification Met:** CCC - **Unit Count:** 1.0 Count ## Images ![K-Type Thermocouple Surface Temperature Probe Sensor, -50 to 500℃ - Image 1](https://m.media-amazon.com/images/I/61cCtORuijL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than expected for the price!
