RAPITEST Luster Leaf Soil pH Meter 1840

Rapitest 1840 Soil pH Meter in Sri Lanka

Battery-Free Analog Soil pH Meter for Garden Soil

The Rapitest Luster Leaf Soil pH Meter 1840 is a simple analog soil pH meter that shows whether your soil is acidic, neutral or alkaline, with no batteries needed. Its probe picks up the tiny electrical currents in moist soil and shows the result on a needle meter. It suits garden beds, lawns and pots. Browse our full range of soil testers in Sri Lanka.

Prepare the soil first: remove the top 5 cm (2 in), crumble the soil beneath to about 13 cm (5 in) deep, remove stones and debris, then wet it with distilled water to a mud consistency. Lightly shine the probe with the supplied pad, avoiding the bullet-shaped tip, then push it in vertically and wait 60 seconds. If the reading is pH 7 or higher, re-shine the probe and re-test at a new spot for 30 seconds. If it is below pH 7, re-test at a new spot for 60 seconds without re-shining. The manual gives no accuracy figures, so treat this as a quick garden-grade guide. It is for soil only, never liquids. If you prefer a digital display, see the Rapitest 1845 digital soil pH meter. Every unit is quality tested, needs no batteries and carries a one-year warranty.
