3000 PPM Solution, 230 ml, for SALT-3000 SALT-3050 Salt Meter Tester Calibration.

Was a reorder. Great to check accuracy.

I like the quantity that comes in the bottle. You can put a small amount in another container to help calibrate my salinity tester. That way your not contaminating the whole bottle when you need to use it. Expiration date is also good because the solution has a two year shelf life.

Use this to calibrate my salt meters. It works well and is cheap enough.

I would recommend taking this to a pool store and have them test the salinity. The bottle I received (lot 624) tested on an analog meter at 2800. I will calibrate my salt reader accordingly. Nice 2 year shelf life. I will get this again when needed.

Not sure where all the negative reviews are coming from. I used it to check my salinity reader and it was accurate showed 3006. Pleased with the product. Not super cheap but it says expired 12/25 so I will use it a few times before it expires.

Have used this for years with no problem but had to return last 2 as they were both same lot numbers but only read about 2400 PPM. Lot # 0624 EXP date 12/2027 is not 3000PPM

You MUST calibrate your salt water pool water tester. Mine came in drastically off, but with this solution I was able to quickly and easily calibrate my tester. Now I can test my salt levels in the pool at home and it is very accurate. If you found this review helpful please mark it helpful so I know to keep writing reviews.

Standard. To test your pool water. Works grest
