Wondfo Digital Basal Thermometer for Women Fertility – BBT Thermometer for Ovulation & Pregnancy Tracking – High Accuracy & LCD Display & Waterproof

Longer Testing Time for Higher Precision – Engineered for fertility and ovulation monitoring, this BBT thermometer uses a longer stabilization period to deliver ultra-accurate results. Keeping it in place for about 2 minutes (oral/rectal) or 5 minutes (underarm) allows the sensor to fully settle, helping you detect subtle temperature shifts in your cycle.
Clinical-Grade Accuracy with High-Precision Sensor – Provides 0.01°F accuracy, comparable to professional laboratory equipment, ensuring consistent and reliable basal temperature tracking for your fertility routine.
Easy °C/°F Switching – Switch between Celsius and Fahrenheit by turning off the device and holding the power button for 2 seconds, making daily operation fast and user-friendly.
Clear LCD Display with One-Button Operation – Features a large, easy-to-read LCD screen and a simple one-button design for an effortless and intuitive BBT-tracking experience.
Multi-Mode Measurement for Personalized Comfort – Supports oral, rectal, and underarm measurements, allowing you to choose your preferred method and maintain consistency for more reliable tracking.
Hygienic Waterproof Tip & Long Battery Life – The waterproof probe is easy to clean with alcohol wipes or disinfectant, and the device offers 200+ hours of use (about 1 year at 3 uses/day) for dependable long-term performance.
Memory Recall for Convenient Tracking – Automatically stores your last measured temperature, making it easy to review changes and follow your daily basal temperature trend.
Important: Longer Test Time Is Normal for Ovulation Tracking – Fertility thermometers naturally require a longer measurement period because ovulation-related temperature shifts are extremely subtle. A reading time of about 2–5 minutes is completely normal and ensures the accuracy needed for reliable ovulation prediction.
