Luster Leaf 1880 Rapitest Electronic 4-Way Analyzer Review

Average Reviews:

(More customer reviews)I bought the rapitest mini 4 way soil analyzer on ebay which is almost identical to this one with three leads. I couldn't help notice how many are complaining that the pH measurements do not work. This is not true. If you follow the directions it measures pH fine.
You need to first clean the right lead with the included pad and wash it. Then you stick the meter all the way into the ground. Then you have to water the ground around the meter leads until it gets muddy almost like water. You will then see the meter start moving away from 7 and if you wait a minute, you'll get an accurate reading. Repeat a few times to make sure you got a good spot that is consistent. If you only insert the very tips of the leads into the soil or do not make the soil into mud, you will get a pH of 7. I've inserted the whole thing into a bottle of vinegar and it measures about 2.5 which is accurate and I've inserted it into a container of peat moss I've watered until muddy and it measures 4 to 5 depending on location. Both are accurate. If I do not follow the instructions and only insert the tip of the leads into the bottle of vinegar or stick it in dry soil or stick it into the soil without waiting a minute I get an inaccurate reading. But if you follow the directions it works fine with an error of about 0.5 pH units in my opinion.
I give it 4 stars out of 5 because the "Fertility Meter" does not appear to really measure N-P-K directly but seems to merely measure the soil's conductivity and assuming most of its ions are N-P-K compounds and therefore has a high false positive rate. When you insert it in liquids that do not have any nitrogen phosphorous or potassium, it reads "high" when it should really read "low". Also the pH meter appears to have a maximum error of 0.5 pH units with repeat measurements in vinegar which is fine for gardeners who don't work in a lab and need perfect results.
