SOLD: Keithley 155 (Wescor MJ55) Null meter

[TheSteve]

I am selling a Wescor MJ55 which is a rebranded Keithley 155 null meter. The MJ55 had a small extra PCB added that used a AA battery to bias an external circuit. The extra bits have been removed and it is now the same as a stock Keithley 155.
You can see more information on it here: https://www.eevblog.com/forum/metrology/wescor-psychrometric-microvoltmeter(-~keithley-155)/
All of the commonly found nasty foam around the batteries has been removed, it is now very clean and works great. I can include a set of original cardboard cased 9 volt batteries that still work if the buyer would like.

SOLD

Any questions please let me know.

I had no idea that they were available re-branded, thanks for such valuable info.

My Keithley 155 is in mint condition and works perfectly, so no need for another one.
But I am sure you will sell them fast.

I sent him a PM, could very much come in handy for verifying a not quite working unit I have.
