Micro Essential Lab 2210 Plastic Hydrion Vivid Short Range pH Test Paper Dispenser, 4.5 - 8.5 pH, Single Roll

I bought this to do some soil testing in my garden. It does the job.

Just what I needed. Quickly ascertain the fluids pH for my plants. Much easier and I honestly think more accurate than the pH pens that I have

This product was useful, and when received was at least one-year prior to expiration.As far as I can tell, over the short useful range of pH 5.0-7.0 which was pertinent to this application, there are no visually highly-contrasting indicator dyes or mixes. So it is not surprising that this (# 2210) and the similarly short-range pH 4.5-7.5 (# 334) are calibrated to 0.5 unit steps. (# 067 5.5-8.0 has a shorter-stepped (unevenly spaced) color chart, but was not useful because pHs below ~5.7 could not be distinguished from one another.)Perhaps the manufacturer has recommendations, but I found that making close color distinctions by eye could be helped by paying attention to lighting. For example, ambient indoor illumination by household-bulbs designed to enhance for certain pleasing tones did make a reading difficult - unless supplemented by a different type of lamp.If of interest, this use was to assess pH of plant nutrient solutions, and to adjust it for better absorption of certain components by the roots in particular media. (And, coincidence or not, the tomatoes this year did indeed turn out quite well.)

Super effective, easy to read. Dip, shake, interpret. Basically the same stuff we use in my biochemistry lab at the university. This is a very convenient sensitivity and detection range for plant fertilizer solutions for regular or hydroponic gardening. Highly recommended. We use this with an electronic pH meter for assurance, and they match pretty closely. We trust these strips. It’s part of a roll, so you tear off what you need. The indicator solution can come off on hands, and that is probably to be avoided.

Works but, for making hard ciders and wines need to have more of a range. Wanted to have the .5 increment range so I went with this one since a 5.0pH is a good place to be when starting fermentation. Most of the ones with a wider range have increments of 1pH. First time using I came in low and realized I needed something that read lower so I also ordered Hydrion S/r Dispenser 0.0-6.0pH paper. Now between the two I have a decent range for my needs.

This is only for pH 4.5 to 8.5 so keep that in mind. It’s accurate. The strip is greenish but have accurate readings, I know some people say they’re suppose to be yellow so I’m not sure. I tested on several things as in the picture to prove myself that it’s accurate. I got it to test my urine pH and for the future for amniotic fluid although I’m not sure how much that’ll work out. You dip and take it out after 1-2 seconds no need to leave it there as I think it will affect the results. Keeping it with a desiccant and rice in the darkness to keep moisture out. Expiration date is on the box it came in. Good expiration date about a year from now.

As someone who dislikes returning products, I had to after noticing that this item expires on 1/1/23. I went through the process of returning for a replacement, only for the replacement to also show the same expiration date of 1/1/23. Now I have to go through another return process and request money back. I will buy it somewhere else.

I have a subscription for the 4.5-8.5 pH testing roll. Most have worked well, but a roll I recently received was defective -- usually, the dry strip isyellow with a hint of green; but this one was yellow like it was already at 4-4.5 pH.... So, it doesn't work. I called the phone nuber provided and it's a sketchy answering machine. Hopefully. It's a legit company and they replace my order.The expiration date is September 2015, so it should have beem good....
