Telepole alternative?

(1/3) > >>

BigBri:
We currently use telepoles, like most of the industry at this point I guess, but have been searching for an alternative.  Mostly due to the unreliable nature of the low range detector and how many ELD errors we get with them.  Some of the ones we have been looking at are the Canberra and the Thermo Scientific  telepole-esque models.  Anyone have any personal experience or insight with the ones I mentioned or even ones I did not?

Thanks

We at the Entergy Nuclear South Central Calibration Facility have been using a low temperature heat shrink to attach the low and high tubes to the board. This along with a probe cover made out of pipe insulation cut our low tube breakage\ELD errors by about 90%. This is across four plants for the last three outages.

SpyCat:
We maintain ~22 Telepoles for daily use @Zion D&D.  Agree that securing the detector tubes can reduce the ELD/EHD errors.  In addition, check for poor solder points there.  Another source of errors is the cord's modular connector getting bent too much.  We invested in a telephone modular connector tool, so we can replace the connectors versus replacing the entire cord (that's not fun).
But our major expense was replacing the #@*!! aluminum poles when the clutches get cross-threaded; we eliminated those poles, and instead use a more rugged "long arm" pole with reasonable tighteners.  This reduced our inst repair parts budget by $75k.
Otherwise, the Telepoles' edge is no meter movement & no rotating display.  The only thing I'd like is a battery % readout, versus "beep hey batteries are dead" indicator.

Eds0123:
Check out "FH 40 TG Teleprobe" good instrument;  but the catch is its made by ThermoElectron or are they ThermoScientific now? anyways; See if you can rent one or two as for testing in the field before you commit spending above $2k per each or more these days. It also could be used as a MicroRem meter. goog luck
