Safety Siren Pro 2 Radon Gas Detector Model HS78512

Pro Series II Radon Gas Detector with ionization sensor and 85db audible alarm is the only electronic radon gas alarm designed for home use. Plug in radon detector and continuous radon monitoring begins. Short-term and long-term average radon level displays after 48 hours. Mutable, audible radon alarm of 85db at 10cm. Beeps hourly if long-term radon levels are 4pCi/L or greater. Accuracy is /-20%pCI/L. Displays up to 999 pCi/L. Radon is a colorless, tasteless, and odorless radioactive gas produced by the uranium breaking down in soil. Accumulations of over 4pCi/L are a long-term health hazard. EPA currently advises corrective action to reduce radon levels below 4 pCi/L (4 Pico-Curies per liter). Sensitive test equipment is required to detect radon gas. Specifications: Sensor: Ionization Chamber. Full scale reading: 999 pCi/L. Short term: Average radon reading over past 7 days. Long term: Average radon reading from time of last reset. Maximum sampling time of 5 years.ically resets after 5 years of accumulated radon data. Audible Alarm: 85db at 10cm. Beeps every hour if long-term radon levels are 4pCi/L or greater.May be muted by user. Accuracy: /- 20% pCi/L. Rounding: Less than whole numbers round down (3.9 = 3 displayed). Averaging Freqency: Levels will be updated on the display every hour. Continuous Monitoring: Display updated hourly. Lock Tab: Screw through tab; detector is tamper proof. Operating Environment: 0° C (32° F) to 70° C (158° F). Storage Environment: -20° C (-4° F) to 85° C (185° F). Dimensions: 4.7" x 3.1" x 2.1". Power Source: Input: 120v AC/60Hz at 9 Watts. Output: 18v DC/200mA. Sensor Voltage: 250VDC. Weight: 8 ounces. Note: The EPA no longer tests any electronic devices such as this radon detector. Each Pro 2 radon detector has a final accuracy test by testing against a high end SUN nuclear radon unit. Third party testing is not yet completed.
