Product s Technical parameters: pH range: 3–8 pH Humidity range: 1–8 pH accuracy: ±0.2 pH Moisture accuracy: ±1% Operating temperature: 5–50°C Note: When using the device, avoid touching the sensor tip when inserting the probe. Do not apply excessive force, as this may damage the electrode. Keep the device away from strong magnetic fields. Do not leave the probe inserted in soil for extended periods. Rinse the electrode with clean water after each use. Package includes: 1 high-precision soil pH and moisture tester. 1. High-Accuracy Portable Soil Tester Soil pH is a critical factor affecting plant health and crop quality. Most plants thrive within a specific pH range; extreme acidity or alkalinity can hinder growth and nutrient uptake. 2. Easy to Use Simply insert the probe into moist soil to instantly measure pH (3–8) and moisture level (1–8). The pH scale indicates acidity (lower values) or alkalinity (higher values); the moisture scale reflects dryness (lower values) or wetness (higher values). 3. No Battery Required This analog tester requires no batteries or external power source. It meets applicable quality and safety standards and is suitable for both indoor and outdoor use. 4. Versatile Applications Ideal for use in gardens, greenhouses, lawns, potted plants, orchards, vineyards, and agricultural fields. 5. Supports Plant Health Helps maintain optimal growing conditions by enabling informed decisions about watering and soil amendment.
