RAPITEST Luster Leaf Electronic 4-Way Analyzer 1880

Rapitest 1880 Electronic 4-Way Analyzer in Sri Lanka

Battery-Free 4 in 1 Soil Tester for pH, Moisture, Light and NPK

The Rapitest Luster Leaf Electronic 4-Way Analyzer 1880 is a switch-operated 4 in 1 soil tester that measures soil pH, moisture, light and combined N-P-K fertility. Move the switch to the test you want and read the needle. It needs no batteries and suits outdoor and indoor use. Browse our full range of soil testers in Sri Lanka.

The switch positions run top to bottom: fertility, light, moisture, pH. Fertility takes about 10 seconds. The light reading is multiplied by 1,000 to give foot-candles, and the pamphlet groups plants into four light categories from 7,500 to 50,000 foot-candle hours. Moisture readings are matched to the watering numbers in the plant watering chart. For pH, polish only the far-right probe with the pad and wait one minute. It does not measure temperature, and the NPK result is a combined, indicative reading. It is for soil only, never liquids. For a digital display and temperature, see the Rapitest 1885 digital 4-way analyzer. Every unit is quality tested, needs no batteries and carries a one-year warranty.
