Universal Instrument for Radon and Thoron measurements in air, soil gas, and water

  • Measurement range: 1 - 10.000.000 Bq/m³
  • Measurement principle: HV chamber - Deposition of short-lived Radon daughter products on a semiconductor detector, alpha-spectroscopy, continuous or interval operation by the pump
  • Sniffing mode for localization of radon entryways
  • Fast mode operation for fast response time
  • High sensitivity with a small chamber volume
  • Alarm mode in case of activity concentration exceedances
  • Sensors for temperature, humidity, barometric pressure, and motion
  • Battery- or mains-operated
  • Freely adjustable measurement intervals on the instrument possible
  • Data memory for 2,047 data records (with alpha spectrum) 
  • DAkkS-conform calibration according to the DIN EN ISO/IEC 17025:2018 included!
  • Optional: data remote transfer

Description:

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 realized by only one button. A serial printer may be connected to the interface of the RTM 1688-2 to present a protocol directly on site.

The Radon/Thoron monitor can be directly connected to a modem (analog, 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 to humidity variations – a drying tube, commonly used in such instrument types, is not required.

Special attention was paid to 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 250 ml must be pointed out. The measurement of probes taken from small and limited volumes is possible due to this property.

The Radon/Thoron monitor RTM 1688-2 can be powered either by a mains power adapter or by the internal battery which gives an autonomous operation time of 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 Radon gas monitor comes with the DAkkS-conform calibration certificate according to the DIN EN ISO/IEC 17025:2018 and the latest release of the Radon Vision software.

A standard calibration is performed at a radon concentration of 3 000 Bq/m³ with the prior determination of the background effect. A second calibration point at a radon concentration of 300 Bq/m³ is possible on demand and at additional cost. A separate calibration certificate is created for each calibration point.
