3-in-1 Soil Tester Meter for Moisture, pH and Light Intensity – Battery-Free Analog Probe for Gardening, Farming and Plant Care

This is a single-unit analog soil testing instrument designed for instant, reliable assessment of three critical growing conditions: soil moisture level, pH acidity or alkalinity, and ambient light intensity. The device operates without batteries or external power—simply insert the probes into the soil to obtain readings in under three seconds.

Physical Specifications

Total length: 260 mm

Head width: 62 mm

Sensor type: Dual stainless steel probe tips with integrated electrochemical and photoelectric sensing elements

Display: Large-scale analog dial with clear numerical markings and directional arrow pointer for easy interpretation

Measurement Capabilities

Soil Moisture: Scale from 1 to 10, where 1–3 indicates dry conditions, 4–7 represents optimal moisture range, and 8–10 signals saturated soil. The reading responds directly to soil conductivity without requiring calibration.

pH Level: Range from 3.5 (strongly acidic) to 8.5 (strongly alkaline), with 7 as neutral. Each plant species has a preferred pH window; this meter helps match soil chemistry to specific crop requirements.

Light Intensity: Measured in lux from 0 (complete darkness) to 2000 lux (bright indirect light). Ideal for determining whether plants receive sufficient illumination for photosynthesis, especially indoors or in shaded areas.

Operational Design

Three-Mode Selector Button: A single push-button switches between MOIST, LIGHT, and PH functions. No tools, apps, or setup required.

Direct Insertion Use: Insert probe tips to root depth for accurate measurement. Clean tips with water after each use to maintain sensor performance.
