Calibration Lab for high voltage, x-ray, MAS meters, oscilloscopes, meters, located in Greenwich, CT, serving the world. Used Dynalyzers.
The Dynalyzer was invented at Machlett Labs by Dr. Shapiro, now president of Greenwich Instrument Co. GiCi has calibrated Dynalyzers since 1988. We buy and sell Dynalyzers.We are ISO 17025 and ISO 9001 accredited.The Dynalyzer was manufactured by Machlett, Varian, Fischer Imaging, and now at Radcal. We service them all.
The GiCi 2000 voltage divider, x-ray voltage divider, bleeder, is the only oil filled voltage divider for x-ray currently in production in the USA ( +/- 75 KV bipoloar). The Monopole divider can operate at 150 KV to ground.
Go to GiCi store to see our selection.
We are buying used Dynalyzer IIIA high voltage units.
Now celebrating 22 years of operation....under the same management at the same location.
No one can beat our turn around time on calibrations of Dynalyzers, Voltage dividers, MAS meters, oscilloscopes and digital volt meters. No one has more experience.
We offer excellent technical support.
Dynalyzer IIIA GiCi 2000 voltage divider
The HV-1 voltage divider has been discontinued. The GiCi 2000 replaces it and the GE bleeder. We no longer have any used bleeders in stock. We recommend you use the GiCi 2000 which is an improvement over the old GE bleeder, and the HV-1. The new bleeder is compatible with the AMX-4 and the Lightspeed CT scanner. The GiCi 2000 is a frequency compensated version of the old GE bleeder, and has the same DC characteristics. It has a switch to provide 10,000:1 ratio direct to scope, or 1,000:1 ratio to 10 meg DVM orother 10 meg load.
We also offer the Parker Medical Monopole divider rated at 150 KV to ground, used with various new GE CT scanners. Calibration to 100 kv is included. Divider available with R-24 or extended federal standard connectors. We can provide calibration to 150 KV with direct reference to our standard which was calibrated by Nist in October, 2010. Our reference standard is invariant after 10 years to 0.05%.
No one has more experience with the Dynalyzer�after all, Dr. Jon Shapiro invented it! We offer quick turn-around, 1 to 3 working days. Many repairs include improved parts so that we can make your unit stronger, and last longer.
Many of the structural changes in Dynalyzer materials were initiated by GiCi. Lexan parts have been replaced by Delrin for many years. Others have adopted these changes. As your equipment can be up to 33 years old, we recommend a mechanical rebuild as a preventive measure. There ARE 33 year old Dynalyzers still in use, and they all have the same accuracy. ALL our used Dynalyzer high voltage units are rebuilt. I am just overwhelmed that this product is still in use. It makes me feel good.
Some of the messed up Dynalyzers we have seen:
Unit on left has broken main divide rod due to a stress crack. It had : wrong crumbly gasket We rebuilt with teflon Gasket
Unit on right has new light pipe and new divider rod. We replace all the nuts and couplings, too.
Rebuild your tank before it fails.
Ask about our Dynalyzer high voltage unit rebuild program...its much more than a repair. It puts much new life into your HVU through the installation of new plastic internal parts: light pipe and couplings, center support, divider rod and check nuts. You can even have new high voltage connectors, if you want!
Our test procedures are most thorough. We check the actual KV and mA waveforms at the end of the procedure to double check that you will receive a working unit, and that there are no residual waveform issues.
We can calibrate and repair all versions of the the Dynalyzer high voltage unit and display.
Why calibrate at all? Just read this paper from Agilent, the cost of calibration is small compared to the consequences.
