The Rapitest 4-Way Analyzer offers the best value, but featuring (4) premium meters in one. This multi-purpose meter allows you to monitor the conditions of soil pH, soil moisture, light quantity and total combined Nitrogen (N), Phosphorus (P) and Potash (K) levels. The extensive instructions guide you through the use of each function and also provide recommendations based on your results. A cleaning pad is also included which allows you to properly scrub the probes between uses. No batteries required.
From the Manufacturer
The rapitest 4-way Analyzer was designed and engineered in the USA to help gardeners measure 3 important soil requirements and sunlight levels, for more successful gardening: Soil pH to determine if soil is acidic or alkaline; total measurement of N, P and K to determine if plants are over or under fertilized; and a soil moisture reading to help prevent over watering of plants. The meter is also calibrated to the Mean Solar Table developed by USDA. It is designed and engineered solely to measure sunlight for plants. The meter uses an exclusive purple chromatic filter to color correct light for plants. No batteries required for operation.

Our Aquaponics farm decided to purchase the Luster Leaf 1880 Rapitest Eletronic 4-Way Analyzer from Amazon, it saved the day. No more lending our rather expensive testing gear.
For once, life made simple, it now resides in our raised beds section of our farm. Thanks Amazon
Of course, you should not expect it to survive many nights outside in the rain, nor will you get the kind of results that NASA would require for a zero-g botany experiment, but for a casual gardener with a few temperamental indoor plants this is a perfect little tool. It will give you a rough idea of how your little patch of soil is doing and can assist you in diagnosing why specific plants seem to be struggling. The most useful setting is the pH tester which gives a acidity/alkalinity reading without using testing strips or dyes. The fertility setting is calibrated for a specific set of ppm for N, K and Phosphorous (these are listed in the instructions) - also useful if you know the mineral requirements of your individual plants.
The instructions included with the unit are printed on a single sheet of paper and are easy to follow. Step by step directions for using each setting are given.
On a side note: I'm not going to risk cracking my unit open but my guess is that this device works by measuring the flow of electric current and bases the results on pre-calibrated resistances. This means there is a battery in there somewhere that will eventually conk out.
Per a previous review, you must completely submerge the meter into wet soil. If you try to use it on dry soil, or not fully submerged, it won't give you an accurate pH reading. Plus, let it sit in the soil for a few minutes so it has time to adjust.
The other three functions ~ water, light, and fertilize, seem to work OK. They weren't my major focus for purchasing this product. Plus, the instructions were poor and too generalized. That's why I gave this product four out of five stars.
Once again, this is a good product for general pH soil readings. You can get a good idea if your soil is too acidic or alkaline.
I was able to verify the soil's pH, the reading the product was displaying, because I have soil test stripes to confirm the pH level. I want to stop using test strips because they're expensive, and I can't reuse them. With this product, there's nothing to replace, such as batteries, or repurchase, such as test stripes.
