Pocket CO Upgrade Plan: Attention owners of Model 100 and Model 200 instruments! For the discounted price of $99, you can upgrade to a Model 300. This new detector is as reliable as your current instrument, but has the advantage of a replaceable coin-cell battery. This new model also allows you to calibrate the instrument yourself (with Home Calibration Kit), rather than mailing it in. Just send your old instrument to KWJ along with thisĀ
Pocket CO Service Form, and a check for $99. Credit cards can also be processed over the phone. ** If for some reason the battery on your Model 100 or Model 200 has died within the 1 year battery warranty period, the TechCheck service will be free of charge (excluding shipping).
