[wesheltonj]

(1) How often must the probe be calibrated?
(2) How often should the probe be calibrated?

Thanks.

2. Once every two weeks

In case you're a little lazy...

I let mine run for 3 months without calibrating and checked it every two weeks with a refractometer... it was consistently right on.

Well, I guess we should check it every 2 weeks with a calbrated refractometer and if the probe is right on then there is no need to recalibrate at that time!

Wow, every two weeks, you need to sell the Calibration solution by the quart or better yet by the gallon, (not liters).

Why?

It is there is enough in the 50ml bottle to last you six months.

Is there a formula to go from the salinity reading to Specific Gravity? Neil

Hiya

If you mean ms to SG, I do not have the formula to hand but can be found on a google search.
