Description and Utilization
TSR4M is designed for continuous measuring of radon concentrations in buildings.
Portable probe basis is a measuring chamber with a semiconductor photodetector. Radon enters the
chamber by diffusion through the input filter on the bottom of probe. The probe measures in autonomous
and time continuous way. It processes results every 4-minute intervals and from this counts short-term
moving average of radon concentration ( 1 hour moving average - average of 15 4-minute process
intervals). It also counts long-term moving average of radon concentration ( 24 hours moving average). The
probe saves time records of these radon concentration values including values of humidity and temperature
within its internal memory (typically at an interval of 1 hour). Next saved value is time record of measuring
energy spectrum (typically at an interval of 12 hours). The probe is random for location in measured place,
but generally it is put on the bottom of the probe. Bottom of the probe cannot be covered. The probe can
be switched on/off by switch. LEDs „STAT“ a „CHRG“ indicate current status of probe see ´Operation
manual´ below.
The resulting values can be downloaded continuously during measurement or at once at the end of
measurement. Data from the radon probe is downloaded to a PC directly via USB interface. Capacity of
internal memory is almost unlimited.
TSR4M Radon Probe can be operated by these ways:
A)
Standalone probe
- Thanks to its independent battery power, portable radon measuring probe
supports flexible placing options within monitored structures. Accumulator will last for more than
1 year after full charging. After switching on TSR4M immediately starts measuring and saving
results into internal memory. The resulting values are downloaded after end of the measurement
by B) way.
