XHW1411 Digital Temperature Controller Clear, reliable readings in humid environments: its waterproof probe, three digit LED display, and calibration function ensure accurate temperature measurement and easy verification across industrial or residential applications. Real time temperature control in prone areas: designed for locations such as fish tanks, fermentation chambers, and HVAC installations where maintaining the right temperature helps prevent overheating or freezing risks. Flexible heating and cooling management: combines heating and cooling modes with interval operation and timer settings to adapt to dynamic thermal demands in laboratories, pet habitats, and small scale industrial setups. Robust performance and compatibility: delivers ±0.3 C precision across a wide range from 55 C to +120 C, with optional dual voltage compatibility (12V or 220V) and a 10A load capacity for reliable control of heating or cooling devices. Practical features for everyday use: straightforward calibration, a waterproof probe, and a user friendly interface support accurate, consistent temperature control in challenging environments. Use scenarios: Aquaculture and fermentation equipment: monitor and control tank or chamber temperature in real time to prevent overheating or freezing. HVAC control points: regulate equipment to maintain stable ambient temperatures and protect sensitive components. Laboratories and small scale production: manage precise heating and cooling cycles with timer and interval settings for repeatable experiments and processes.
