Air Quality and Noise Precision Equipment

The Casella CEL-633C1 is a Class 1 precision sound level meter designed for comprehensive environmental and occupational noise monitoring. It enables simultaneous measurement of key acoustic parameters, including broadband levels and frequency-based analysis using octave and 1/3-octave bands. The instrument integrates advanced digital signal processing, onboard data logging, and optional audio recording, supporting both short-term field measurements and long-term monitoring programs. It complies with international standards, including IEC 61672 and ANSI S1.4, ensuring suitability for regulatory assessments.

The GrayWolf 6-Channel Particle/Mass Meter (PC-3016A) is a portable, high-precision aerosol monitoring instrument designed for real-time measurement of airborne particulate matter across multiple size fractions. The system simultaneously measures six particle size channels (0.3–10 µm and above) and provides both particle count data and derived mass concentration (µg/m³), including PM₁, PM₂.₅, PM₁₀, and Total Suspended Particulates (TSP).

The GrayWolf AdvancedSense XM / DirectSense XM System is a regulatory-grade environmental monitoring platform designed for real-time measurement of air quality, gaseous pollutants, and key environmental parameters. The system integrates the AdvancedSense XM handheld meter with DirectSense XM smart probes, enabling simultaneous multi-parameter monitoring through a modular, plug-and-play sensor architecture.
