Sounds as though you already have experience in balancing and also possibly analyzing data.

A good start, in my opinion, would be to buy a good used 2120-2 channel CSI analyzer and the necessary equipment for balancing with the 2120. If your venture did not work out, you would not be out but a couple of thousand dollars in USA currency and could possible get some of your investment back by selling the 2120.

You would also need an RBM or AMS Suite software program. From what I understand, there are some used versions of the RBM/AMS Suite software for sale.

This analyzer has a good "fastbal" program and also handles your basic and advanced analysis projects. Then, if all goes well, you could always upgrade to more modern 2130 or 2140 analyzer.

I think that CSI no longer, to some degree, supports these older analyzers and software

Just my opinion and I could be wrong, even with my 30 plus years using a 2120.

Good Luck,

Ralph

IMO, I would be very cautious about the purchase of a 2120.  In another thread (see https://www.maintenance.org/topic/no-more-2120-s) you will find the following text...

"I must inform you, however, that as of Jan 1, 2006, the 2120 is now out of production. Let me also assure you that this decision was driven by technology. As an expression of our continued commitment to our customers:

* * * EMERSON WILL CONTINUE TO SUPPORT THE 2120 THROUGH THE END OF THE DECADE. * * *

We will offer both 1 and 3-year support agreements for the 2120, as long as the term of the agreement does not extend past Jan. 1, 2010. We also offer repair and calibration on a one-time fee basis as long as feasible through the end of this decade and beyond. The CSI 2120 Machinery Healthβ„’ Analyzer is a solid and viable instrument that will last for many years to come."

That basically means support ended somewhere around 2010 ("...end of the decade").

CSI 2120 is one of the best and probably it was the best at its time.

Purchasing a second-hand unit or one without vendor support is a business decision. It has some risks but its advantage is the very low initial investment. Some customers may ask for a calibration certificate which could be another issue. However, there are "small shops" that claim they do repair and calibration for this model (I never contracted them, though).

Thank you everyone for your inputs.

Cost is important factor for making decisions, regarding which equipment I should go for.

Can anyone one give feedback on Kohtect C911.

Is it mandatory to buy software (e.g. DDS from Adash or similar kind from other manufacturers ) to analyse data collected through analyser ?

 

A consideration with software to support older units might be the OS on current computers.  I know of a few products that use software that will not run under Windows 10.

John,

I understand what you are saying about CSI not supporting them for the past 10 years or so.  

But, on the other hand,I know of several people (outside contractors) who have and still are using them since the 1990's. In fact, the company where I used to work part-time, after I retired from a paper mill in 2002, are in their 25th or 26th year of use and still going strong. Never had to have any major repair work on any of them. Just calibrated a few times during those years (but not from CSI). Only had to purchase a new battery very few times (from some company selling batteries to fit the analyzers other than the original CSI).

Just a suggestion, on my part, for a newbie coming into the business. Just in case the business doesn't work out for him, he would not have high dollars invested. I definitely am not in the business of trying to sell them.

I know a guy in Spain who bought one a year or so ago to start his own business and is doing very well with it.

Thanks,

Ralph

The profile for the OP says he resides in Nepal.  Service on any product, the logistics of getting it to/from a facility, etc. may be a major factor.

One of my friend had shown me demo of this product.

You will have tough time with the software, i personally did not like it much.

Kohtect C911 is an alignment kit and I would not buy it as a vibration analyzer.

Please factor into account the amount of time and effort you will put up in making reports and analyzing vibration data as well.

Cheapest is always not the best solution.
