In that case you take 1000 ml of soil in a mason jar and add 500 ml of distilled water and shake and let it set for a while. After setting a while you strain the water through a coffee filter and catch the liquid and test it the EC and pH. Very accurate.
Thanks. I've heard the process before and forgot about. What are you testing with?
I use an Oakton pocket pH meter. This is my second one, the first one lasted about 5 years and worked well so I got another one after the first one died.

@oneeye could you possibly comment on the use of the EC meter to determine relative nutrient density in a plant.
I don't know anything about plant tissue testing. I love testing soil and potting mixes. The TDS meter will only give a total amount of salts and not what each salt is. So its a basic test for total ppm in the soil. If I wanted to test for nitrates, then I would use a different testing method using a reagent solution as well as different reagents for other nutrients. If I use a complete fertilizer, then all I need to know is the total ppm to see everything work. Its so easy using meters and well worth the time.
I have tested many of the the low-priced soil probe meters and have found them to give mis-readings and not dependable. The most reliable meters I have found are the liquid meters for pH, EC, and TDS readings. The punch in the ground meters are a rip-off in my opinion. If they were any good I would have one.
I've had the same results but I'm telling you the Yinmik meter works in soil and water.
