How each alternative compares

PRO-LAB Short-Term Radon Test Kit

The device is smaller, measuring 6.69 by 3.54 by 1.18 inches and weighing just 5.76 ounces. You gain detailed app-based analytics and flexible placement options. You give up the simplicity of a 48-hour EPA-approved snapshot. This monitor is ideal for users who want ongoing air quality data rather than a one-time screening result.
