A leap forward for smart sensing technology in indoor air quality, occupational hygiene and environmental monitoring applications

Spurred on by over a quarter-century of feedback from users across the globe, GrayWolf’s DirectSense® XM represents a significant step forward in smart sensing technology. This compact, adaptable probe-datalogger is designed to meet the rigorous demands of professionals working in indoor air quality, occupational hygiene, environmental monitoring, HVAC validation, and sustainable building assessment. Whether deployed as a hand-held instrument, on a desktop, or mounted to a wall for long-term use, the DirectSense XM supports up to eight interchangeable, plug-and-play smart sensors, each engineered for precision, reliability, and ease of use.

The device’s internal memory enables months of autonomous datalogging, reducing the need for constant external connection and making it a cost-effective solution without compromising on performance. Its broad range of sensor options, including TVOCs, CO₂, formaldehyde, and various toxic gases, makes it highly versatile for both targeted spot checks and continuous environmental monitoring. Built-in fans help stabilize readings and speed up response times, while the rugged, ergonomic design ensures dependable operation in demanding field and laboratory conditions.

Smart sensor technology is central to the DirectSense XM’s appeal.
