Clean and bright fully overhauled Weston Light Meter - the essential camera accessory for determining exposure of your photographs. Because of its simplicity and reliablity, the Weston Master Light Meter became a dependable practical aid to determining correct exposure with professional and amateur photographers. This classic light meter operates without batteries. It has a selenium light sensitive cell. When exposed to light, the cell generates a small electric current that deflects the needle of an ammeter coil within a stong magnetic field. The lightmeter is entirely dependent on the light sensitivity of the selenium cell for accuracy. Over the course of years, the selenium cell will age, tire, and degrade.

Old Selenium Light Meter Cell

(10x magnification shows surface of old selenium cell from a Weston 'V' meter).

Such old meters have lost their normal sensitivity requiring ever stronger sources of light to deflect the needle. The defective selenium photovoltaic cell must be replaced with a new one for true sensitivity and accuracy to be restored to the meter.

The meter mechanism is guaranteed to be restored and cleaned and unclogged of ferrous dust and with a new selenium cell fitted. Tested in excellent working order.


" It’s even more beautiful than I thought it would be. Thank you very much. I may not shoot like Ansel Adams….but I will feel like an old pro with my new Weston - Pascal "


Good afternoon, Ian
My meter just arrived - looking better than when I bought all those years ago. It works perfectly and the reprint of the instruction book (I never had one, because I bought the meter second-hand) is an added bonus.
Thank you so very much and keep up the good work.
Kindest regards

Hi Ian,

Thanks for a perfect service. Received the Weston this morning and delighted to have this piece of my photographic past restored and ready to go. Although this is not my original Weston (as I said I gave that to my niece, who is living in the USA) it is the same model that saw me through my Architecture degree (my photographic comfort blanket :) and when I saw one for sale it was too hard to resist.

All the Best,


Fife Scotland

PS thanks for attaching the chord, much appreciated. However I already have a book of instructions, so if you wish me to post it back to you (no cost) please let me know, it will be no bother.
