If its taken care of , about how long will it stay accurate?

[Chuck S]

I usually as a general rule use distilled water to calibrate mine every 3 months so I can't rightly answer that. /ubbthreads/images/graemlins/wink.gif

As a general rule it is to calibrate any equipment every so often.

[brody98]

Is that the one you have or do you use something else?

That is the exact one that I have and works great. Like Chuck said though just calibrate every few months or so.

I too use the same one, and I have been rather bad lately and I haven't calibrated it lately, so I decided to check if it did need calibrating. It held it's calibrations for 5 months now. It is going on four years old.

Just got done ordering it ...thanks guys

[brody98]

Just got it today, but I don't have any distilled water to set it up, can you substitute R/O DI water instead?

[brody98]

No need to answer that last question I got some distilled water at the store today

[tendar]

yes

[brody98]

Oh well /ubbthreads/images/graemlins/smirk.gif now I have both and enough distilled water to calibrate it for about 70 yrs /ubbthreads/images/graemlins/grin.gif
