This manual provides operating instructions for the SARAD DOSEman Pro radon monitor, covering setup, measurement, maintenance, and technical specifications.
The SARAD DOSEman Pro is a portable radon monitor that measures alpha potential concentration (PAEC) and equilibrium equivalent concentration (EEC) of radon decay products. It operates by continuously sampling air through a built-in pump and filtering it onto a membrane, which is then analyzed using an alpha spectrometer to distinguish between Po-218 and Po-214 activities. The device features a single-button operation with a lock function, a 3x12 character display, and internal rechargeable battery support for up to 48 hours of continuous operation. This manual is written in Chinese.

Under normal environmental conditions, the filter membrane should be replaced at least every 500 hours of operation, or once a month.
The minimum response time is 2 hours, which is required to reach equilibrium for the final result.
The internal rechargeable battery can support continuous operation for approximately 48 hours.
Communication is achieved via an infrared adapter connected to the PC's USB port, running as a COM port.
