RAPITEST Luster Leaf Digital 3-Way Analyzer 1836

Rapitest 1836 Digital 3-Way Analyzer in Sri Lanka

Digital Soil pH, Fertility and Temperature Meter with Coil-Cord Probe

The Rapitest Luster Leaf Digital 3-Way Analyzer 1836 is a 3 way soil meter (3-in-1) that measures soil pH, fertility and soil temperature from one handheld unit. A bimetallic soil probe with a sure-grip handle connects through a flexible coil cord. Arrow keys select the test and a blinking arrow on the display shows which one is active. Browse our full range of soil testers in Sri Lanka.

The fertility reading covers nitrogen, phosphorus and potash in combination, and is shown on a 0–9 scale: 0–2 too little, 3–7 ideal, 8–9 too much. For temperature, push the probe 5–8 cm (2–3 in) into the soil and wait 60 seconds. The manual includes a vegetable germination chart in °F. For pH, the probe goes 10–13 cm (4–5 in) deep into tamped, muddy soil. This is an indicative garden-grade meter for soil only, never liquids. If you also need moisture and light readings, see the Rapitest 1885 digital 4-way analyzer. Every unit is quality tested, comes with batteries included and carries a one-year warranty.
