KWJ Engineering of Newark, California, has announced the arrival of the Pocket H2S Pro, a key-fob sized, personal hydrogen sulfide detector that weighs less than one ounce.

The nanotechnology-enabled instrument protects from low-level and high-level exposure to H2S, and gives real-time Time Weighted Average, Maximum, and Total Exposure readings.

The Pocket H2S Pro also features three alarm types, a replaceable coin cell battery, and data/event logging capability.

“All H2S detectors out there do basically the same things,” says company President Dr. Joseph Stetter.

“They all have alarms, have a similar range, similar lifetime, etc. Ours is the only one that offers all of those features in a less than one-ounce package. Why carry around a big, bulky instrument to get the same level of protection?”
