TSR4 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.

The resulting values can be downloaded continuously during measurement or at once at the end of
measurement. Data from the radon probe can be downloaded to a PC directly via USB interface or
wirelessly via antenna and Central Unit. Central Unit is not included with package of TSR4 and it is sold and
delivered extra ; see
TSR4 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 TSR4 immediately starts measuring and saving results
into internal memory. The resulting values are downloaded after end of the measurement by B) or
C) way.
B)
Probe connected via USB
–
Using usbRADONview app and USB cable is possible to download
results to PC continuously during measurement or at once at the end of measurement.
usbRADONview application, drivers and user manual is free downloaded on website:
C1)
Wireless network for radon measurement
- Central Unit supports simultaneous data downloads
from up to 16 probes. All values are saved again into central unit memory. Via connected
computer to Central Unit and TERAview application on PC it is possible to download and process
all data from system and configure whole system. Setting and configuration of TSR4 Radon Probe
and whole system is also managed by TERAview application on PC. TERAview application version
3.11.6 and higher, drivers and user manual with detail configuration description is free
downloaded on website:
In case of time continuous measurement of radon concentration or in case of setting in
regulation system the probe must be placed in radio range of Central Unit. Distance (radio range)
between TSR4 and central unit is up to 600m in open space. In buildings it depends on number of
walls, building material, etc. Strength of radio signals (RSSI) is monitored by Central Unit. If radio
signal strength between individual elements is insufficient, TSR4 radon probe must be inserted or
repeater must be used to extend the signal; see
