Bacharach Pro-125 Question

Is to send the meter back to Bacharach to have the sensors replaced and calibration done. I don't remember the cost for this, but I think it was near $100 for the O2 sensor.

We have 36 of these units in service since the bigining of the year. 14 have gone back to bacharach for oxygen sensor problems (under warranty). All problems related to moisture getting in the unit. Bacharach says the 3 most important things are 1. Keep them dry, 2. Keep them dry, and 3. Keep them from freezing.

Our guys love the Pro 125. If you can keep them dry, you'll love them too.

    Bacharach Pro 125 Sensors need replacement

    Has anyone had to replace the sensors on your Bacharach Pro Combustion analyzer. I have the chance to get a used one at a reasonable cost but I looked up the online prices and it seems like both sensors and a calibration kit would be around 300.00 plus. E-Mail me directly if you know of a more reasonable price on these sensors.

    Thanks, Rich
