A few weeks ago I posted a review of the PicoCount 2500 pneumatic traffic counter. The folks at Vehicle Counts have figured out the issue and sent out the following recall notice. I've been impressed with their customer service and am glad that they've tracked down the problems I wrote about.
We have been getting reports of our PicoCount 2500 counters failing in the field. Upon receipt of these units we found that the battery had been drained. It has taken awhile, but we have finally traced the problem to improper cleaning of the boards in assembly. Trapped impurities were causing a short inside the units which eventually drains the battery. Since our units are potted for life, the only solution is to replace the units affected by this assembly mistake.
This condition applies to any units built prior to serial number 10051063.
Your units have been identified as the units from the bad run of assemblies. Even though the counters may be operating okay now, they could fail without warning at any time. We have built into the latest release of TrafficViewer Pro a test of the counters that might give you a warning of an impending failure, so at least you can catch it before putting it out for a study and having it fail.
We are in the process of replacing all units that are suspect of containing the production flaw. Simply send them to us and we will immediately replace them. Your units are covered by a 10 year warranty, this is a warranty replacement, and the new units will continue your warranty.
We apologize for any inconvenience this unfortunate problem may have caused.
