Professional Gage Repair Service since 1959
test indicator and dial indicator repair

Our family has been repairing test indicators and dial indicators since 1959 and, with a third generation in training, we have no intention to stop. It gives us great pleasure to return damaged gages back to full working order.

Why don't we repair calipers and other gages? We don't want to spread ourselves thin. Remember the addage: "Jack of All trades, Master of None"? We would rather excell at indicator repairs with a zero rejection rate and a focus on satisfied customers than trying to please everyone in the industry with slow and mediocre work.


Your indicators will be repaired as follows

  • total disassembly
  • cleaning of all parts with appropriate cleaners
  • inspection of all parts under high magnification
  • repair or replacement of all worn or damaged parts (those parts which are necessary for the full functioning of the gage)
  • lubrication with appropriate lubricants
  • reassembly
  • inspection for functionality
  • calibration using equipment and standards certified traceable to NIST
  • your satisfaction is guaranteed upon return of gage or we'll issue credit, refund or rework as per your instructions

Current turn-around time

Calibration Certificates NIST Traceable


All repaired gages are calibrated with NIST traceable standards or measuring equipment.

On request, short-form Certificates of Calibration are included free with all test indicator and dial indicator repairs.

Your gages will be certified that they have been calibrated using standards and equipment which are traceable to NIST (National Institute of Standards and Technology). Our certificates are designed in conformance with ISO/IEC Guide 25.

We DO NOT provide calibration for gage blocks, ring gages or other standards. Those items should be sent to a local calibration lab. Let us know if you need help finding one.


2018 Fixed Rate Repair Costs


Our Fixed Rate prices are for a completely refurbished instrument as described at the top of this page. The price includes labor and replacement of damaged parts. We will charge you separately for any parts that are missing and for the replacement contact points on test indicators. Please allow us the right to return any gage not repared for reasons such as extensive damage, obsolete models, unavailable parts, lack of know-how, etc.

The fixed costs shown below do not include replacement of parts which are missing. Be sure to send all parts along with the gages in the event that they have fallen off or have been disassembled.

Warranty Repairs


How about warranties on our repair services? It's simple: your satisfaction is guaranteed. If within 90 days of invoicing the gage malfunctions again through no fault of your own, we'll repair it again or issue credit, whichever you prefer.




It is the customer's responsibility to perform final inspection and verify accuracy before using any repaired gage.

The customer will most certainly want to know the extent of any reading errors which have to be taken into consideration when using these gages for precision work.

Although the gages may leave our premises in top-notch condition, we can not be held responsible for gages going out of calibration during the stress and turmoil of shipment. This applies even in cases where calibration certificates are supplied.
