Sales Bulletin 20200325 ALL-TEST PRO 31TM MCA Instrument to be Discontinued May 6, 2020


The first generation of the venerable ALL-TEST PRO 31TM (AT31TM) was released for sale in the early 2000’s .Thousands have been sold worldwide and helped establish ALL-TEST Pro, LLC as the leading provider of light weight, portable, handheld instruments for field testing of electric motors and other coil based equipment.

Given the excellent success of the ALL-TEST PRO 34 TM (AT34 TM) and ALL-TEST PRO 7 TM (AT7 TM), it is time to discontinue the AT31 this year.

We will discontinue selling the AT31 on May 6, 2020 (Limited Stock Still Available, get your final stock orders in, first come, first served) and this is our formal 45 day notice to ATP distributors, representatives, and resellers.

We anticipate supporting the AT31 instrument hardware for 2 years from May 6th, 2020 and existing computer software (Condition CalculatorTM) is compatible with 64Bit Windows 8.1, & 10 operating systems. We have no plans to provide further updates to AT31 computer software products.


As I hope all of you know by now, there is no direct upgrade path from the AT31 to an AT34 or AT7, therefore, we know there are existing AT31 users that may choose to continue using the instrument. Some of these instruments in the field may be quite old and this provides an opportunity to sell a replacement AT31 to them before they are discontinued.

We have a limited number of new AT31 in stock ready for sale and you will only be able to buy them without the orange protective glove part#40005

Remaining stock is on a first come, first serve basis!
