CoMo 170 / 300
Hand-held Contamination Monitor
CoMo 170 is one of to the most modern instruments in the field of surface contamination monitors. A key advantage of the CoMo-170 is the innovative detector technology, which does not use any gas-flow or gas-filled detectors at all. A thin-layer plastic scintillation detector is used. This type of detector is both α and β/γ sensitive. In case of mechanical damage of the detector foil, the detector does not have to be repaired by the manufacturer. Time consuming and expensive repairs (usual or xenon detectors) are no longer necessary.
Note: The CoMo 300 is a variation of the CoMo 170 and differs from the CoMo 170 in the features below:
| Features / Names | CoMo 170 | CoMo 300 |
| Detector size | 170 cm² | 300 cm2 |
| Background noises | α approx. 0,1 cps, β/γ approx. 15 -20 cps | α approx. 0,1 cps, β/γ approx. 20 -30 cps |
| Dimensions | 280 x 125 x 135 mm (L (with handle) x W x H) | 318 x 157 x 172 mm (L (with handle) x W x H) |
| Weight | approx. 800 g (including batteries) | approx. 1,000 g (including batteries) |
| Special versions | CoMo-170 D : with additional GM counter tube integrated into the front for measurement of the dose rate | CoMo-170/-300 G : with thicklayer plastic scintillation detector |
Working with open unsealed radioactive material can lead to contamination of persons, equipment and surfaces. Therefore, regular controls are mandatory to ensure the safety of humans and the environment. Mobile contamination monitors such as the CoMo-170 or CoMo-300 are used for direct and indirect contamination measurements. Combined with dedicated accessories, these powerful measuring devices provide a complete solution for contamination control and clearance measurements.
CoMo Wall Station
The wall station makes it possible to easily check your hands for a definable time (e.g. 5 sec) for contamination. Additionally, the rechargeable batteries inside the CoMo are charged by the wall station.
CoMo Floor Bogey
Floor trolleys for up to 3 CoMo. Floor trolleys for 1 – 3 CoMo systems are available to monitor large floor areas. This makes it easy to carry out indoor or outdoor measurements.
