water from the sponge until it no longer drips.

Calibration and Verification
Calibration and Verification
The PosiTest LPD is shipped with a Certificate of Calibration
Calibration
showing traceability to a national standard. For organizations with
re-certification requirements, the PosiTest LPD may be returned at
regular intervals for calibration. DeFelsko recommends that our
customers establish their instrument calibration intervals based
upon their own experience and work environment. Based on our
product knowledge, data and customer feedback, a one year
calibration interval from either the date of calibration, date of
purchase, or date of receipt is a typical starting point.
A PosiTest LPD Verifier is available for verifying the accuracy of
