NAP−503
NAP-503 is a newly-developed version of NAP-505. The appearance and structure are exactly same as NAP-505, but this new version has a lower sensitivity to hydrogen gas. While NAP-505’s sensitivity to hydrogen gas is about 40% of the sensitivity to CO gas, but NAP-503’s sensitivity to hydrogen gas is only about 10% of the sensitivity to CO gas. Thus NAP-503 has much better gas selectivity. An appropriate type can be selected depending on users’ applications. As there are various types of NAP-503 as shown below, please contact us for detailed information.
