Is the meter water proof?

I would not submerge the whole meter in solution. Only the bottom 1 inch to extend the life. If accidentally dropped in water and quickly removed likely ok. I try to only put in the probe on all my meters.

Where can we buy replacement tips/probes?

Don't know and wouldn't buy anymore of their products. My ph pen never worked and neither did a heating pad a had gotten. Took it as a lesson, didn't even want the replacement. Went with blue lab, pricey but worth it

How to calibrate temperature? My unit is reading ~8F too low

I tried two and both had terrible temperature accuracy. I bought a cheap $19 Taylor Precision digit thermometer which gave superior accuracy.

Does this do Fahrenheit?

Garbage! Go with blue lab. Pricey but at least it works
