TEZZCO Repairs & Maintains CSI Vibration Analyzers

Data Collectors Models 2120, 2130, 2115, & 2110



  • Avoid forced obsolescence & the capital expense of a forced change to new products.

  • Save up to 50% on current service contracts depending on volume.

  • Gain a qualified alternate service provider for your existing CSI vibration data collectors/analyzers.

Candidates for Savings: If you have 1 or 400 CSI vibration analyzers in use, you know that the CSI 2120 was declared obsolete and soon will no longer be supported by Emerson. 

Why the 2120?  There are thousands of CSI 2120s out in service and they have proven to be a good product. It makes no sense to Tezzco to see a good product dumped so Tezzco keeps the CSI 2120s used by small shops, consultants, and large corporations repaired and calibrated, supplying batteries and other basic necessary support items to keep them productive likely for years to come. 

  • Repair & Maintain CSI Model 2120

    Tezzco can repair, calibrate and maintain CSI Model 2120 single and 2-channel portable vibration analyzers / data collectors. 

  • Repair & Maintain CSI Model 2130
