What would someone recommend as a backup to Fluke 7250LP (0 to ±10, 0 to ±30 in-H2O). Since Fluke is taking 8 to 12 months to repair/calibrate pressure standards, we need backups. In the old days we had a Dwyer 1430 Microtector for 0 to 2"H2O ±0.00025 in-H2O and a Dwyer 1425-24 Hook gauge for 0 to 24 in-H2O ±0.001 in-H2O.
We have most of the parts for our Hook gauge but are running into an issue with the port at the bottom of the wells. I think the thread pitch is different than 1/4" NPT.
We use Additel pressure gages for things that low. We use their small hand pump also so that we can control small pressures down to 2 inH20.
We are calibrating the Additel units.
Contact Process Instruments in Pittsburgh. We do not repair the Fluke units but turn time is 2 weeks on calibration. Email me if you have questions about our capabilities. malters@procinst.com
