Designed to clamp onto 3/4" or 1" pipes, its durable glass lens ensures longevity without yellowing, making it ideal for monitoring boiler lines, water heaters, and various process lines. ## Description The REOTEMP S2-F1 Pipe Clamp Surface Hot Water Thermometer is a quality thermometer for use on pipes, boiler lines, water heaters, process lines, or hot water pipes where a clamp attached thermometer is needed. The thermometer offers an approximate reading of the temperature inside the pipe by sensing the temperature on the pipe surface. Please note some heat loss will occur as the temperature conducts trough the material of the pipe and thermometer. The thermometer accuracy is rated at +/- 2.5-2-2.5%. The S2-F1 features a glass lens that will not yellow over time and an easy-to-read 2.5" dial. The temperature range is 32 to 250 Fahrenheit. This unit comes with a 1-year limited warranty. Review: Works as advertised.. accuracy is.. close... - I am using this on a hydronic floor heating system for the return (cold) side. I already have a combination temp/pressure gauge on the hot side, but its nice using this to see the return water temp side. It gives a good idea of the temp drop through the loops. Its a little loose on 3/4" pipe with the length spring they send, but you can shorten it up and it holds fairly well. If you are going to mount it where there is vibration you may want to consider gluing it to the tubing instead. Accuracy is.. close. I checked with a temp gun and it seems to be off by about 3 degrees at 155F. Obviously, wouldnt be using this on anything that requires a much greater accuracy, but for my purpose its just fine. We'll see how long it lasts - but no complaints so far. Review: Works as advertised - Seems to be well made and accurate. Side note: (1) This product works through thermal conductivity, so there is going to be lag time until the display catches up. (2) Since the pipe I attached it to is round, and the back side of the thermometer is flat, I added thermal paste (nasty stuff to work with) to increase its surface area. (3) The dial face is adjustable, there are two very small set screws on the back. Loosen them and rotate the dial body to make your adjustments. So, overall Iā€™m satisfied with my purchase. ## Features - Non-intrusive Temperature Measurement, Reads the Approximate Surface Temperature of the Pipe - Easy-to-read 2.5" Dial, 32 to 250 Fahrenheit with +/- 2.5-2-2.5% Accuracy - Clamps to 3/4 in or 1 in Size Pipes - Glass Lens Will Not Yellow Over Time - For use on boiler lines, water heaters, or any process line where the approximate surface temperature would be helpful to monitor. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08BJ9DB9V | | Additional Features | Non-Contact | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #32,426 in Baby ( See Top 100 in Baby ) #25 in Dial Thermometers #489 in Baby Health Care Products | | Brand | REOTEMP | | Brand Name | REOTEMP | | Color | Steel | | Customer Reviews | 4.1 out of 5 stars 128 Reviews | | Display Type | Analog | | Included Components | 1 count (Thermometer only) | | Indoor Outdoor Usage | Outdoor | | Item Length | 2.5 inches | | LowerTemperature Range | 32 Ā°F | | Manufacturer | REOTEMP | | Model | S2-F1 | | Model Name | S2-F1 | | Outer Material | Glass | | Part Number | S2-F1 | | Product Care Instructions | Wipe Clean | | Resolution | 0.9Ā°F | | Response Time | 500 milliseconds | | Reusability | Reusable | | Special Feature | Non-Contact | | Style Name | Industrial | | UPC | 853850002560 | | Unit Count | 1 Count | | Upper Temperature Range | 250 Ā°F | ## Product Details - **Brand:** REOTEMP - **Special Feature:** Non-Contact - **Color:** Yellow - **Age Range (Description):** Adult - **Included Components:** 1x REOTEMP S2-F1 Pipe Clamp Surface Hot Water Thermometer - **Outer Material:** Glass - **Display Type:** Analog - **Product Care Instructions:** Wipe Clean - **Unit Count:** 1 Count - **Model Name:** S2-F1 ## Images ![REOTEMP S2-F1 Pipe Clamp Surface Hot Water Thermometer - Image 1](https://m.media-amazon.com/images/I/61tKCbi-V0L.jpg) ![REOTEMP S2-F1 Pipe Clamp Surface Hot Water Thermometer - Image 2](https://m.media-amazon.com/images/I/61E86k-3xEL.jpg) ![REOTEMP S2-F1 Pipe Clamp Surface Hot Water Thermometer - Image 3](https://m.media-amazon.com/images/I/61Wi2ySMCyL.jpg) ![REOTEMP S2-F1 Pipe Clamp Surface Hot Water Thermometer - Image 4](https://m.media-amazon.com/images/I/61iVMzTveQL.jpg) ## Customer Reviews ### ā­ā­ā­ā­ā­ Works as advertised.. accuracy is.. close... *by D***N on October 18, 2021* I am using this on a hydronic floor heating system for the return (cold) side.
