RTM 1688-2 - Radon and Thoron monitor


New: Stores now 2047 data records, selection of sampling interval also by push button!

 Radon entry paths can be discovered by the "sniffing” mode. Soil gas sampling as well as Radon in water measurements are simple because of the built in pump.

The operation of the Radon/Thoron monitor is realised by only one button. A serial printer may be connected to the interface of the RTM1688-2 to present a protocol directly on site.

The Radon/Thoron monitor can be directly connected to a modem (analogue, ISDN, GSM) for remote data transmission. 


The Radon Vision software (included in delivery) handles the telephone connection as simple as a direct cable link.

The measurement chamber is not sensitive against humidity variations – a drying tube, commonly used in such instrument types, is not required.

Special attention was paid for the issue of quality assurance. Each stored data record contains a complete Alpha spectrum which shows the error-free operation of the instrument for each single integration interval. Any number of measurement series may be created by starting/stopping the data acquisition. The data stored within the instrument can be read by PC even if a measurement is in progress.

The small chamber volume of only 130 ml must pointed out. The measurement of probes taken from small and limited volumes is possible due to this property.

The Radon/Thoron monitor RTM1688-2 can be powered either by a mains power adapter or by the internal battery which gives an autonomous operation time up to 14 days.

As a matter of course the instrument is equipped with sensors for temperature, humidity and barometric pressure. An integrated tilt detector will give a signal if the Radon/Thoron monitor has been removed from its original position during the measurement.

The software for the operation and configuration of the monitor is included. The transport case can be ordered.
