With 3 probes connected I quickly found issue I was having. I let this machine log every 30 seconds for 48 hours and it worked flawlessly. I have no complaints about the machine. The instruction book is hard to read, the print is so small and my eyes can't read the fine print anymore. Had to print off manual from internet to make it legible. Seems typical with manuals now a day. Would recomend if you need a temperature data logger. ### ⭐⭐⭐⭐⭐ soddisfatta *by on Reviewed in Italy 15 June 2025* il termometro funziona molto bene ### ⭐⭐⭐⭐⭐ Excelente 👌🏻 *by on Reviewed in Mexico 2 January 2024* Producto de buena calidad, tal cual la descripción 👍🏻 ## Frequently Bought Together - Digital 4 Channel Thermocouple Thermometer Temperature Recorder Data Logger AZ Instruments Multi Channel K Type Thermometer Thermocouple Reader with 8G SD Card 2 Bead Type K-Thermocouple Probe - szzijia 5pcs 3M K Type Mini-Connector Thermocouple Temperature Probe Sensor Measure Range -50~700°C - PerfectPrime TL1004 K-Type Sensor Probes Metal HeadProbe for K-Type Probe Thermocouple Sensor & Meter in Temperature Range from 0 to 500 °C --- ## 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.pt/products/286646913-digital-4-channel-thermocouple-thermometer-temperature-recorder-data-logger-az](https://www.desertcart.pt/products/286646913-digital-4-channel-thermocouple-thermometer-temperature-recorder-data-logger-az) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-21*
