Is it possible no calibration on pressure gauge
Our calibration cost per pressure gauge is 60 bucks and 1 unit of pressure gauge about 40 bucks..as such our team member suggested get the pressure gauge change every year instead of send for calibration, save cost.. What do you all think? need you all input.. Thanks in advance.
good idea.... i will rather buy a new pressure gauge instead if it can save the cost... :happydance:

only considers the gauge to buy has its calibration certificate
Yeah I'm not sure how that is going to pan out. If the Calibration is only good for one year how long after it's calibrated will you get it if it even comes with a certificate of calibration? If it gets to you 3 months after calibration you'll only be able to use it for 9 months...
I find myself in the same situation with NIST thermometers and backflow preventers. It more cost efficient to replace with new ones than it is to recalibrate.

We purchase new temperature guns every year instead of having them calibrated for this reason - new ones are less expensive than calibration itself.
Is new equipment can be exempted from calibrate although no certificate provided by suppler? Accepted by auditor?

Dear carine,
So how do you justify the reliability of any of your data output if the unit is of unknown calibration ?
Of course, if the accuracy/precision of the data is (justifiably) irrelevant to yr process validity/safety, then the auditor should be equally uninterested.
The specifically auditorial problem arises from the necessity of evidence, eg documentation rather than hearsay or trust.
So yr question is perhaps effectively one of Supplier Approval ? :smile:
