[APD] Extech Instruments pH probes

[Dave Wilson <aqua_green at bigpond.com>]

Hello,

Is there anyone who has had any experience with Extech pH probes.   There is
a model offered that has a refillable probe.   I was wondering how they
perform in a hot humid tropical environment.   Here it in NT of Oz is hot
all the time and very humid for about 4 months.   Most of the pH pocket size
probes I have tried over the years seem to die just after the warranty runs
out.



There is also the manufacturer of the products web page

Anyone scared of being sued email me privately.

Thanks 
Dave Wilson
