It protects an. The rest of this review holds the listing to exactly that brief — limits, alternatives, and the ranked guides included.

Honest Limits

The limits are operational: a detector only protects when its sensor is alive (bump test before use), accurate (calibration on schedule), and matched to the gas and range actually present. Sensors age out as consumables, and a reading from the wrong sensor class is not a reading.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.

Our methodology

Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
