Ph Test Strips, 160 Full Range Strips 1-14 Universal Litmus Paper Soap Making For Water Saliva Wine Urine Soil, 2 Packs Of And 6 Units

For testing radiator pH I needed a tweezer to dip. However, worked well and saved a lot of money for a suggested radiator flushing (previously done) that was not needed

These strips are convenient and work great. I recommend storing them in a plastic bag so humidity doesn't degrade them.

They don’t seem to change color no matter what I test… maybe a faulty batch?

Ph value for most part is accurate but functionality is a lil iffy the rooms light or sunlight kinda changes it to where it’s hard to tell it says keep outta light which I get but kinda hard to tell the ph color then.

Bought these to test the ph of my fish tanks before adding triop eggs and they worked perfectly and were very easy to read! Triops are extremely sensitive to ph and they hatched within 24 hours so id say these are very accurate strips.
