Semiconductor sensor tester with digital and cartoon display — delivers fast, sensitive, easytoread results on a fivelevel scale: Verygood, normal, not sogood, bad, very bad. Key benefits Accurate and fast results: Builtin semiconductor sensors provide fine sensitivity and quick response so you get reliable readings without waiting. Easy to understand: Results display in both numeric (digital LCD) and cartoon modes so anyone can interpret the outcome at a glance. Safer for your eyes and the environment: Orange backlight uses low energy, offers soothing colors, and minimizes eye strain during viewing. Simple operation: Designed for straightforward use — no complex setup or training needed. Core features and performance Sensor type: Semiconductor sensors for sensitivity and prompt response. Display: Digital LCD combined with cartoon indicators for dualformat feedback. Result grading: Clear fivelevel scale — Verygood, normal, not sogood, bad, very bad — for immediate, actionable interpretation. Energy and eye care: Orange backlight that saves power and provides comfortable, nonharsh illumination. User experience: Intuitive interface for quick checks by users of all experience levels. How it solves problems Eliminates guesswork by converting sensor readings into clear, standardized levels. Reduces reading errors with dual visual formats (numeric and cartoon). Helps users make quick decisions thanks to fast sensor response and immediate display. Typical use scenarios Home selfchecks: Quick, easy testing at home by any family member — no technical expertise required. Workplace screening: Fast onsite checks for staff or visitors where clear, repeatable results are needed. Educational or demonstration use: Simple visual output makes it suitable for teaching or quick demonstrations to groups. What to expect when using the tester Power on, allow the sensor to stabilize, perform the test, and read the result on the digital LCD or the cartoon indicator. The fivelevel result makes it easy to decide whether further action or a followup check is needed. Reliable, energyefficient, and userfriendly design that delivers clear, fast results without complicated controls.
