Hi All, 

 

I would send my pressure gauge out every year for calibration, each cost about 50 bucks each. Lately i have replaced pressure gauge with new one with cost 30 bucks each. As such, can i replace d pressure gauge every year instead of sending out for calibration , this for cost saving purpose?

Hi,

 

yes you can change them with the new one but take into account that you should check the validity of the calibration of the new devices. Yes if is from approved type they should be calibrated as e new but the calibration start to be counted from the production date, not when you are buy. For this reason will be good to check their documents and the information about the calibration. Its depend and what is the legal requirements in your country about this measure devices.

In any case you should have proves that they are calibrated and the validity of the calibration, only explanation that they are new is not enough.

Success!

 

Best regards,

Ivan

As long as the new one is factory calibrated and you have full documentation on each purchase/replacement, etc that would be fine.

 

We have several clients that purchase new back-flow units every year instead of having them checked by a local authority - the savings per unit is about $50.00 every year and they also get scrap value out of the used ones.

New still needs validation. Factory calibration adds $ to the sale price.

good question

 I never really considered that...I always take the one which is out of calibration (thermometer) and " donate" it to production personnel for their personal use.

 With a pressure gauge I am not sure how you can get rid of it without impacting the environment

If you can confirm that the new gauge comes with a calibration certified to an acceptable standard (ASTM, NIST, etc), and that you have the means to verify its calibration, and yes, replacement of equipment can be performed in place of normal third party calibration.

 

If the new unit does not come with documentation certifying its calibration to a recognized, acceptable standard, then you would still have to pay to get it certified in order to be compliant.

The replace versus re-calibrate debate.  All responses above valid.

 

One thing to consider and keep in mind is the company's environmental policy.  Such as, can you recycle or reuse the old device?  Or will it just add to your trash?  Our company just achieved zero waste so this is something we consider with everything we have and everything we purchase, it is a requirement.  It can make some things difficult (such as sourcing environmentally friendly Styrofoam coolers since we go through about 15 a week).  But in the end we are helping by not purchasing as many things versus reusing or recycling what we can.

Yes you can but how do you know that the pressure gauge have been working for the last week, month, or even year is in spec?

2-year old thread but thanks for comment.

 

Sadly, In the absence of a practical solution (?), the answer appears to be Trust without Verify.
