STS Contamination Monitor Simulator

Updated: Jul 9

The Contamination monitor simulator is a wall-mounted mains powered unit that replicates monitors such as the Thermo CM9/11.

The system features a DP6 style frisking probe with an automatic background check and monitoring activated by removing the probe from the cradle.

The unit features a full colour 7” touch screen with counts displayed and a bar graph visual indicator for both Alpha and Beta Channels. The meter is powered directly from a 240v or 110v mains supply via a wall plug.


The unit features a comprehensive menu system with user definable settings :

  • Apha Alarm

  • Beta Alarm

  • Display Units

  • Display Mode

  • Contamination Check

  • Monitoring Time

  • Background Monitoring Time

  • Changing Background Threshold

  • Operation in High Background

  • Background Substitution

The units respond to STS’s proprietary LS1 liquid simulant spray which may be used to show cross contamination and contamination clean-up.

The unit is supplied with a 12 month warranty and with no requirement for annual calibration or service the ongoing cost of ownership is minimal.

The case is powder-coated steel with an integral wall mounting plate. The probe hanger is included and suitable for a DP6 probe only.


The probe connector is a 5 pin binder ensuring that the unit cannot be connected to a real probe.


The meter is supplied with probe and cable, manual, charger and 1 can of LS1 simulant.
