Create your own custom sponge shape using the included 20 cm x
20 cm (8" x 8") flat sponge sheet.
1. Draw your custom shape on the dehydrated sponge and cut it
out. Be sure to cut a hole in the center for connecting to the base
or extension tube.
2. Use clean tap water to wet the custom sponge. Squeeze excess
water from the sponge until it no longer drips.
3. Connect the sponge to the base/extension tube using the two
round washers.
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

PosiTest LPD detectors and is an important component in fulfilling
both ISO and in-house quality control requirements. Learn more at:
