Adjustable Sampler Probe Model AP3 & AP4
Probes

The adjustable sample probe is designed to be inserted and withdrawn manually into a pressurised pipeline. The depth of insertion can be set at any desired length.

 

A locking gland once set, locks the probe at a set insertion length. After this has been set the tube can then be retracted by removing the locknut and loosening off the locking gland. For sampling the end of the tube should be set within the centre 1/3rd of the pipeline.

 

The probe may be inserted with the pipeline under pressure providing the force required to insert the probe is not too great. If the force required is too great it will be impossible to insert the probe under pressure, or there is a danger that the probe could be damaged/bent.

 

The recommendation is that no more than 30 kg force is used.
