The supplied thermocouple has a small enough thermal diffusivity that one must wait a bit in order to get a stable reading. I have used the supplied thermocouple to compare readings with an older K-type thermocouple using two of these boards. The readings were essentially identical. So while I do not have a way of checking absolute accuracy, I do see good repeatability. At room temperature the reading from the board is within 1 degree of an independent thermometer. The supplied thermocouple is not intended for high temperature operation, but does seem to operate up to at least 600 F. When doing so, the insulation in the lead cable smokes, but the reading is still good. I have been using this board with and Arduino and a different (high temperature capable and faster responding) K-type thermocouple to control a kiln up to 1500 F with good performance. Review: Works well, but thermocouple has slow response - Decent accuracy: Ice water measures 40F, Boiling water measures 190F, higher temps correlate well with multimeter thermocouple. I'd say +/- 10F. Slow response time: The K junction sensor is a rugged solid and takes minutes to reach equilibrium temp. The Time Constant seems to be between 300 to 400 secs, depending on the temperature. Excellent price. Biggest complaint is that product should include a couple of M6 nuts. I had to make a trip to Home Depot. ## Features - Interface: SPI - Test Temperature Range: 0Degrees Celsius ¨C 1024Degrees Celsius, the converter temperature resolution is 0.25Degrees Celsius - Operating Voltage Range: 3.0 ¨C 5.5V; Operating Current: 50mA - Operating Temperature Range: ¨C20Degrees Celsius ¨C 85Degrees Celsius - Module Size: 15mm * 28mm, with a 3mm diameter screw holes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HT871SO | | Best Sellers Rank | #57,741 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #82 in Temperature Probes & Sensors | | Brand | HiLetgo | | Current Rating | 50 Milliamps | | Date First Available | July 1, 2016 | | Is Discontinued By Manufacturer | No | | Item Weight | 0.64 ounces | | Item model number | 3-01-1104-B | | Manufacturer | HiLetgo | | Material | Copper | | Maximum Supply Voltage | 5.5 Volts | | Measurement Accuracy | ±0.25°C | | Mounting Type | Flange Mount | | Output Type | Digital | | Package Dimensions | 4.21 x 2.48 x 0.71 inches | | Style | Modern | | Upper Temperature Rating | 85 Degrees Celsius | ## Product Details - **Brand:** HiLetgo - **Current Rating:** 50 Milliamps - **Item Weight:** 18.14 g - **Material:** Copper - **Style:** Modern ## Images ![HiLetgo DC 3-5V MAX6675 Module + K Type Thermocouple Temperature Sensor Thermocouple Sensor Set M6 Screw for Arduino - Image 1](https://m.media-amazon.com/images/I/61n5RQZDeoL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: The temperature range is listed as "range: 0¡ãc 1024¡ãc," what is this? i am looking for some that can measrue up to 1000 c.** A: As the data sheet said for this, the converter allows readings as high as +1024°C, and exhibits thermocouple accuracy of 8LSBs for temperatures ranging from 0°C to +700°C. The output is given in a 12 bit, digital number. In the electrical characteristics, there is a Temperature error for range from +700°C to 1000°C, you should check that as well. This is the link for de data sheet: https://cdn-shop.adafruit.com/datasheets/MAX6675.pdf **Q: Will this screw probe create a watertight seal?** A: It might if you are careful. The front end seems solid and water proof. The back end (where the wires come out) is not water proof. I am assuming that the front end will be in water. If you were to use a couple of rubbery washers as gaskets, you could keep the back end dry and happy. Personally, I put a plastic sheet around the whole thing. **Q: Are these submersible in water? I have two in a bath, averaging the temperature but I am getting wrong readings as opposed to when they are in the air** A: The sensor is not waterproof (the wires under the mesh are not covered in any plastics). **Q: From the transmitter temperature range is 0°c - 1024°c, but it's not clear what the temperature range is for the k-type thermocouple. please confirm.** A: From: https://en.wikipedia.org/wiki/Thermocouple#Type_K Type K (chromel–alumel) is the most common general-purpose thermocouple with a sensitivity of approximately 41 µV/°C. It is inexpensive, and a wide variety of probes are available in its −200 °C to +1350 °C (−330 °F to +2460 °F) range. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Acurate and easy to use *by A***R on September 23, 2023* The MAX6675 works as advertised and is easily connected to an Arduino Uno R3 using the instructions supplied.

MAX6675) works as intended. The thermocouple also seems to measure correctly but the response is very slow. After dipping the measure/hot end into boiling water, it took 30 seconds or longer to reach within a few degrees C of 100. I'm not sure if the measure junction is insulated well from the casing, if there's just a lot of thermal mass there, or if it's something else that causes the slow response time. Some other K-type thermocouples I ordered seem to be about just as accurate and respond to changes in less than a second. However, the junction at the measure end is exposed. ## Frequently Bought Together - HiLetgo DC 3-5V MAX6675 Module + K Type Thermocouple Temperature Sensor Thermocouple Sensor Set M6 Screw for Arduino - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - ELEGOO UNO R3 Board ATmega328P with USB Cable(Arduino-Compatible) for Arduino --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/31970837-hiletgo-dc-3-5v-max6675-module-k-type-thermocouple-temperature](https://www.desertcart.co.uk/products/31970837-hiletgo-dc-3-5v-max6675-module-k-type-thermocouple-temperature) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-14*
