Today's display is the Heathkit GC-1005 digital clock

But it's not just multimeters! Here are some digital thermometers with displays (and a digital panel meter). Made by Jenway, Thermo Electric, and Strainstall. I also have a couple of frequency counters which I'll post photos of later

Here's a close-up of the display on the Data Precision 3500. The instrument has a bank of relays inside for auto range switching, and a BCD interface connector on the rear

But to carry on the theme, how about two digital multimeters: Datron 1057a on the bottom and Data Precision 3500 on the top. Data Precision has a red filter over the neon orange Panaplex displays

After a positive response to the photos, here's a tube instrument: the Fluke 8120A Digital Multimeter, introduced in 1972

I do like instruments with displays -- I have quite a few. Maybe I should post more photos of them

I did try “ringing” the Addmaster 01 Hotline number – but strangely no one answered. So I repaired and restored this vintage 1972 Addmaster calculator myself. It uses an early gas discharge “Panaplex” orange display.
