## Overview

The 1880 Rapitest Electronic 4-Way Analyzer is a compact, battery-free device engineered in the USA to measure soil pH, moisture, fertility (N-P-K), and sunlight levels. Featuring a 3.5-inch probe for deep soil readings and an exclusive purple chromatic filter for accurate light measurement, it offers gardeners a comprehensive, easy-to-use tool with detailed instructions to optimize plant growth across a variety of garden types.

## Description

Product Description 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.

Review: Good value - Given the price, you can't expect lab accuracy. It's a good value. A couple of comments: 1 - You need to scrub the probes before using. There is a scrubby sponge in the box. 2 - Succulents are having their day in the sun, but this unit will not work for gritty succulent soil. Not enough soil contact, probably, and certainly you can't make mud of it for pH. 3 - Light is measured in LUX, which is really not a measurement of anything plants need. You can get the same measurement on your cell phone. But a light meter that measures PPFD is quite expensive. LUX can be a good proxy measurement for outdoor sunlight, but for plants under grow lights like houseplants and seedlings, it's pretty useless.
Review: Good Value - OK Precision - The first meter I ordered from desertcart did not seem to function properly. The pH and moisture seemed OK, but fertilizer always seemed to read at the low-end of ideal and light always seemed to read 2000 fc no matter how bright or indirect the sunlight. I filled out a return online and had a replacement within 3 days and a free return label -- good service. The replacement unit seems to function OK. Over the range of pH 6-8 the meter seemed accurate. I tested pH on distilled water (it was 7), on baking soda (it was 8) on soil of known slight acidity (it was 6-6.5). However, when tested on very acid soil (verified to be pH 4 with a chemical test kit), the meter read between pH 1-2. The moisture meter seems to work fine. It read 0 on dry soil, 9 on soaking wet soil, and somewhere in between on moderately damp soil. The light meter was way too sensistive. I compared it to a professional meter and it was reading 1000 footcandles when there was only 200 fc. I "recalibrated" it by putting black tape over 95% of the sensor on top until the readings matched the professional meter -- it is now more or less correct. The fertility meter seems pretty accurate. I mixed up a batch of half strength Miracle-Gro fertilizer solution and poured it over some old spent soil and took a reading -- it read "Too little". Using regular strength MG it read "Ideal" and using double strength MG it read "Too much". I've used this weekly to monitor my fertilizer levels and tell me when to reapply my liquid fertilizer to different vegetables and this is the most useful (and difficult to find) function on a meter like this. Something to note, you MUST insert the probes a full 3.5 inches into the soil for an accurate reading. This makes it difficult to use the meter in very hard clay soils or in shallow house plant pots (like my Bonsai trees). - Rob Thompson
