Our Standard Service has become very popular with many of our customers. Many Utilities take advantage of this service during their scheduled maintenance shutdowns, as a part of their QA/QC and Periodic Maintenance practices.

We also offer probe Repair and complete Rebuild Services. We have seen some pretty distressed instruments over the years, rest assured ... we can help.

ASI is committed to communicate with you on a timely basis, provide accurate and detailed evaluations on equipment sent to us for a Service Quote, and to provide the Quality that you expect

- Dilution Probe Standard Service In-Depth -

Our Standard Service includes an overall external cleaning of the probe-tip and probe lines, visual inspection of the unit for any defects; cracks or galled threads, and leak-tight testing for the probe lines. Our lab then tests for aspirator performance to then complete the initial evaluation of the unit, and determine the appropriate means of internal cleaning. Internal flushing of the aspirator and all internal paths is done with use of special cleaning solutions as part of the service. Ultrasonic baths and diluted HCl flush cycles are performed to remove internal blockage or buildup from the aspirator if its efficiency is below factory specs. After the cleaning or acid solution has been neutralized and removed from the aspirator, it is then flushed with Ethanol & dried with purge air. As a final step to ensure that any residual moisture is removed, dry heated purge air is run through the aspirator. After the final testing has been completed, the test data is recorded and a Performance Certificate accompanies the serviced probe. If the diluting probe-tip (in-situ) had been sent in with the compact in-line filter on the dilution air line, we will have replaced the 60u cartridge. Same with the filter cap assembly, we will have replaced the coarse inlet screen. We also apply anti-seize compound to the probe tip threads, filter cap threads and internal threads of the front mantle … hence, it's good to send in those extra parts!

Other Services offered:

We also offer a Mid-level Service that covers minor repairs such as probe-tip thread repairs (in-situ type), probe tube replacements, etc., and includes the Standard Service.

For units that require overhaul/rebuild, we offer an Extended Service. If the unit doesn't pass leak-tight test or there is internal damage to the aspirator, this service would be used. Basically any repairs that would require disassembly of the probe-tip is considered “Extended” service. Any Extended Service will also include the Standard Service. We are always happy to evaluate the unit and submit a quotation for any additional parts or repair beyond the Standard Service before proceeding.

Critical Orifice Service includes cleaning, testing and fine-filter replacement. Keep in mind that if the piece is cracked or if there is a chip on the stem, we may be able to repair this. If there is blockage, we can usually get that taken care of with no problem. If we receive the part and ultimately determine that it is unserviceable, there is no charge for the service if you purchase a new one at that time. A Performance Certificate is also provided to you, noting the nominal flow rate verses the actual tested flow rate after the service. *Always remember to remove orifice from probe-tip before shipping!

Please give us a call if you have any questions or are preparing to send in equipment for service.
