The Analytical Industries Palm CO Carbon Monoxide Analyzer is portable, accurate and affordable; and our customers tell us this unit is extremely easy to use. The user-replaceable thermally compensated sensor maintains accuracy levels that exceed dive industry standards. Just hold the Palm CO directly to the cylinder valve outlet and crack open the valve slightly until the reading is stable; works with both Yoke and DIN valves with only one hand and no adapter needed! A blue tee adapter for optional use with a yoke valve is also included. An optional 2 liter-per-minute flow sampling adapter for the standard BC inflator hose quick-release fitting is also available. This adapter makes it easy to check your gas even after you have attached your regulator to your tank. An optional padded storage bag is also available.

The durable impact resistant housing is sealed for excellent water resistance, includes an on/off switch and allows for user-replacement of the two 1.5V AA alkaline batteries with an approximate life of 13,000 hours of continuous use. Ergonomically designed to comfortably fit your hand, the Palm CO offers a very compact form factor of { 2.7 in | 6.9 cm } wide by { 4.1 in | 10.4 cm } tall by { 1.4 in | 3.6 cm } deep and { 7 oz | 196 g } weight. With a user-replaceable carbon monoxide sensor and typical sensor life of 24 months, the AII Palm CO Carbon Monoxide Analyzer is an excellent value solution for your long-term needs. A calibration gas (bump gas) that must be obtained locally is suggested to confirm functionality before each use.
