This probe detects the gas given off by the STS simulant, which has been applied to the surface to be monitored. This “radiation” may be detected by passing the probe close to and slowly over the surface, as would be done with a real probe when used by a skilled operator. Too fast, or too far away results in no detection – excellent training! Cross contamination can easily be demonstrated, as can decontamination – both benefits of using a “real” contamination, even if not radioactive. The contamination lasts at room temperature for 1-2 hours but totally evaporates within 24hrs leaving the training area ready for the next exercise.

The STS Ludlum Model 12 can be used with any of the STS probes, including AP3, DP2, 44A, HP 210, HP 260, DP6 etc. The STS Ludlum Model 12 is in use in power stations, nuclear fuel processors, hospitals and universities.

STS manufacture a wide range of simulators for most manufacturers products. We are happy to consider your specific task.
