1. Product Overview
The HM-G310 is a deploy-and-measure radioactive aerosol detector built for fast, reliable air contamination monitoring at nuclear power plants, fuel processing facilities, and emergency response sites. Simply install the snap-in filter cartridge, power on, and begin continuous sampling — the unit handles radon compensation, spectral analysis, and alarm management automatically so operators can focus on safety decisions rather than instrument setup.
Whether mounted permanently at a stack exhaust point or carried to a suspected contamination zone, the HM-G310 delivers real-time alpha, beta, and I-131 concentration readings on a clear 7-inch touchscreen, with automatic tri-color alarms that instantly alert staff when action levels are exceeded.
2. Key Features & Operational Benefits
7-inch Touchscreen Display: View live readings, trends, and alarm status at a glance without scrolling through menus.
Automatic Radon/Thoron Compensation: Built-in peak-fitting algorithm separates natural radon signals from real contamination automatically. Dramatically reduces false alarms and unnecessary investigations.
Dedicated I-131 Channel: Get immediate iodine-131 activity readings without sending samples to a remote lab. Accelerates thyroid-protection decision-making during incidents.
Smart Artificial vs. Natural Discrimination: The instrument automatically flags man-made contamination, saving hours of manual spectral review.
Continuous Unattended Operation (12+ Hours): Deploy and walk away. The HM-G310 monitors around the clock with no operator intervention required.
Instant Tri-Color Alarm: Green/Yellow/Red visual indicators plus audible alarm ensure no threshold breach goes unnoticed, even in noisy plant environments.
Fixed or Mobile Deployment: Bolt it to a wall for permanent stack monitoring or carry it to a new location in minutes for rapid contamination surveys. One instrument covers both use cases.
High Flow Rate (up to 50 L/min): Faster air throughput means faster results and shorter response times compared to low-flow samplers.
Tool-Free 50 mm Snap-In Filter: Swap filters in seconds — minimizes downtime between measurement cycles.
