Can these reference solutions be used with different meter brands?

Yes, growers can use them widely among many popular brands of meters using the NaCl scale.

Are the solutions checked for calibration?

Yes, General Hydroponics technicians check each batch to ensure that they are exactly calibrated each time they are used.

What is the shelf life of this item?

I purchased my 8 oz. bottle about 4 years ago, still works great. I transferred some into a smaller bottle to use, then refilled it when emptied.

NO, this is not iodine. This is just a special kind of dye that changes color depending on the acidity of a solution.

Can I put 3 drops of the solution in an 8 ounce cup of water?

I would not advise 3 drops for 8 oz to be accurate. The container that came with my original test kit only holds about 1/2 tablespoon of water. So, if you want/or need to test 8 ounces, you would have to calculate how many 1/2 tablespoons are in 8 oz. Approximately 32, times that by 3, you get 96 drops. So, it would be easier and more economical to test 1/2 teaspoon of water. Hope that helped.

Can I use this to test the pH in Kombucha?

I think it will work to test booch just never allow this to cross contaminate food or beverages.

Is the buffer pH 4 coming with certified quality?

I don’t think so. The bottle does not indicate any official tracking lot or date. I did calibrate my pH pen with it and the spa seems to respond correctly to the readings from the pH reader.

Do I only need to calibrate near my target range?

You always need to calibrate two points. If you desire to measure between 4 and 8, I would calibrate at 4 and 7. Some will tell you to calibrate at three points. The three points would be 4, 7, and 10. I do not think that is necessary. pH 7 should always be one of your calibration points. You should store your pH meter in pH probe storage solution between uses.

Will this solution root cuttings?

This is not a plant nutrient it is a solution for pH machines. I had bought it because it said plant nutrient had to get a refund.

How does the test indicator solution rate? Reliable or should I stick with a pH meter?

Very reliable. I use both though to be spot on.
