RAPITEST Luster Leaf Digital Soil pH Meter 1845

Rapitest 1845 Digital Soil pH Meter in Sri Lanka

Digital Soil pH Tester with Stainless Steel Probe for Root-Level Readings

The Rapitest Luster Leaf Digital Soil pH Meter 1845 is a battery-powered soil pH tester with a digital display and a stainless steel probe for readings at root level. It comes with a guide listing preferred pH for over 400 plants, so you can match your result to what you grow. Browse our full range of soil testers in Sri Lanka.

Press the power button, push the probe vertically into moistened soil and wait 60 seconds. If the reading is pH 7 or higher, re-shine the probe with the supplied pad, re-test at a new spot and wait 30 seconds. If it is below pH 7, re-test at a new spot for 60 seconds without re-shining. Prepare the sample by removing the top 5 cm (2 in) of soil, crumbling the soil beneath to about 13 cm (5 in) deep and wetting it with distilled water to a mud consistency. The documents give no accuracy, range or resolution figures, so use it as a garden-grade guide. It is for soil only, never liquids. If you also want moisture, temperature 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.
