Digital Thermometer with Dual LED and 2 Probes

This high‑accuracy digital thermometer features a dual LED display that can simultaneously or alternately show readings in both Fahrenheit and Celsius, accommodating different user preferences. It supports a wide DC input voltage range of 4‑28V, offering great adaptability. The measurement range extends from ‑67°F to +248°F (or ‑55°C to +120°C), sufficient for most industrial and everyday applications. Included are two waterproof NTC probes (model K‑017), allowing simultaneous monitoring of two different locations—for instance, aquarium water temperature versus ambient air, or HVAC supply and return air temperatures. Its high sensitivity and accuracy make it a reliable tool for professional HVAC technicians and serious hobbyists.
