Metalmark launches Pasoh indoor environmental quality sensor

Metalmark has launched Pasoh, a new indoor environmental quality sensor, and introduced the Metalmark Assessment to help healthcare networks, schools, senior care communities, and workplaces monitor indoor conditions across sites. The offering adds continuous sensing, analytics, and planning support as organizations face longer wildfire-smoke seasons and greater pressure to prepare buildings for air-quality events.

Why it matters: - Pasoh gives organizations continuous visibility into indoor conditions that can affect health, comfort, and building performance. - The new Metalmark Assessment adds analysis and planning support, which can help teams move from raw readings to preparedness decisions. - The launch comes as wildfire-smoke seasons lengthen and organizations face higher expectations for indoor environmental readiness.

What happened: - Metalmark launched Pasoh, an indoor environmental quality sensor, on August 3, 2026. - Metalmark also introduced the Metalmark Assessment, a fixed-scope engagement built around Pasoh measurements and planning support. - The offerings are available now as part of the Metalmark platform of products and services. - Metalmark says the new tools are aimed at healthcare networks, schools, senior care communities, and workplaces.

The details: - Pasoh measures particulate matter from PM0.5 through PM10. - The sensor also monitors carbon dioxide, TVOC and NOx indices, formaldehyde, carbon monoxide, ozone, temperature, relative humidity, and ambient sound level. - Pasoh does not record or transmit audio. - Metalmark’s cloud-based analytics turn those signals into views of indoor environmental conditions across rooms, buildings, and time periods. - The system includes notifications and operator-facing dashboards through Metalmark’s web and mobile applications. - The tools are designed to help teams identify patterns, compare sites, and support preparation and planning. - For organizations using Metalmark’s Tatama self-renewing air cleaner, the data can help compare conditions before and after Tatama operation. - The Metalmark Assessment includes an approximately 60-day Pasoh deployment. - The Assessment also includes access to Metalmark’s cloud-based analytics, a report with a spatial digital twin, key findings, and recommended actions. - The Assessment can include an optional smoke-preparedness plan informed by relevant recommendations in ASHRAE Guideline 44-2024. - Metalmark describes the Assessment as a practical starting point for understanding current conditions and informing future preparation and planning.

Between the lines: - Metalmark is positioning Pasoh as more than a monitoring device by linking sensing with interpretation and planning. - The emphasis on room-by-room and site-by-site visibility suggests the company sees static air-quality readings as incomplete for building operations. - The product pitch also reflects a broader shift toward operational resilience, not just air measurement.

What's next: - Organizations can start with a Metalmark Assessment and use the findings to shape site-specific response plans. - Metalmark expects customers to use the data for smoke-event preparation, day-to-day indoor environmental management, and communication. - The company will continue offering Pasoh and the Metalmark Assessment alongside its other patented products.

The bottom line: - Metalmark is bundling continuous sensing with analytics and planning support to help organizations understand and manage indoor air conditions with more precision.
