Yes, he seems like a good person.  He certainly has the expertise, being an engineer who worked on the R&D of the Minispec at Exploranium.  Please note that, since SAIC no longer supports the GR-130 series (as of this August), he's the only source of full service/calibration for those instruments.  I hope that he has an apprentice.


Cheers

Some weeks ago I posted for help with a defective Exploranium GR-130 portable 
aI-Spec.
Calibration routine failed).
hanks to the very pleasant help by
Irian Komar
rom Radiation Monitor Services
n Kleinburg, Canada
who gave us advice by means of several E-mails
e could fix it with only a screw driver and a HT-Voltage-Multimeter.
hat´s what I call good service!
Somebody told me
[...] an instrument like this, being used for such an 
mportant purpose should be repaired and calibrated by the factory only.
e are talking about  instruments with a value of about 10,000 USD each, 
ompared to that what is postage?[...]"
ou are right, but we never used THIS device to produce watertight, lawful, 
esults.
e use it for a quick overview.
As somebody else said in this forum:
The GR-130 is a rugged, reliable, easy to use, field spectrometer.  It is not a
aboratory device.  It is not quantitative but you can get pretty good
uantitative data if you train your techs on its
 proper use. Overall, we have
een satisfied with the unit. "
And the same applies to Irians help.
End of the ad ;-)
