The Rapitest 4-Way Analyzer is a multi-purpose meter that allows you to monitor the conditions of soil pH, soil moisture, light intensity and total combined nitrogen, phosphorous and potash levels. NO batteries required.
The soil’s pH level will effect how well plants utilize the total nutrients available in the soil. These nutrients are the building blocks the plant requires for healthy growth. Optimal growth can not be achieved with inadequate or improper light amounts. And even if these three key growing conditions are ideal, a garden will not thrive if over or under watered.
Available size: 7.5 in. long
DIRECTIONS FOR USE:
Step 1: Slide the selector switch to the test being performed.
Step 2: For the pH or fertility tests, prepare a soil sample and insert the probes into the sample. Within seconds the meter will indicate the pH or fertility conditions of your soil. Check your results against the detailed pH preferences list (included), or determine if a fertilizer application is required based on your readings.
Step 3: To determine moisture level, just probe the soil deep at root level to measure whether watering is necessary. The moisture guide (included) will help you determine if the soil is sufficiently moist.
Step 4: Light is measured by placing the photocell, located on the top of the meter, at leaf level and pointing it directly at the light source. By checking the chart (included), you can tell if your plants are receiving the necessary light.
Note: Do NOT use with liquids.
