Can I use it to hold a door open? My garage door automatically closes, a nuisance when you're bringing in groceries.Instructions for using a budget TDS meter...
1: take the meter and find a door in your house that seems to swing open all the time.
2: take the meter and wedge it under the door so it holds it closed.
You now have the perfect doorstop.
3: go and buy a Hanna, or a bluelab
Works like a charm, everytime.
