Rapitest 4-Way Analyzer

This small, remarkable 3-probe analyzer measures the four most important aspects of a plants health: light, soil moisture, soil pH and soil fertility. The light reading where the plant is located, the moisture level where it counts, at the root level, the pH level of the soil measured on a scale of 0 to 9 and a combined nitrogen, phosphorus, potash reading determined on a “too little” or “too much” scale on the soils fertility. Durable and compact in size, this permanently calibrated meter does it all.
