Has anyone had much experience with Additel products? Specifically, the Additel 760 Automatic Handheld Pressure Calibrator.

I have always wanted to try their instruments but have never had a chance to evaluate any of them. If anyone has either positive or negative experience with them I would appreciate any info you would be willing to share.

PM me if you don't want to post publicly.
Thanks.

I've used the 761 for years and I would highly recommend them. The customer service is very responsive and the instruments have been very reliable.

I have one also... 
We are adding Pressure Calibration to Metrology.NET and found it to be a great tool for not only automation but also Training.  It's small lightweight, battery operated and portable!

What I like the most is how well it ramps up or down to the set point and hits it without overshoot.

I have calibrated several of the low pressure standards. The 0 to 1 in-H2O and 0 to 10 in-H2O model has the best regulation I've seen.  When I calibrate them, I use the Additel to regulate the pressure and it holds steady our to 5 digits ±2 on our 7250LP. They are also easy to adjust when needed. Additel has been very responsive for technical assistance. Their handheld process calibrators are also good quality.
