FS - X-Rite 361T B/W Transmission densitometer

[jp80874]

The X-Rite 361T is a B/W Transmission densitometer designed to meet the quality control needs of the Graphic Arts industry. It is used to determine the contrast ranges of modern large format film.

To my knowledge it is the only available densitometer to offer both UV and ortho modes, so it is great when working with alternative processes, and is the standard densitometer for silver gelatin printing to get those film speeds and printing times just right.

None of the units I saw on eBay mention the calibration strip. The X-Rite 5 step calibration strip. Serial # 003579 or P/N 361-68. It is included with this unit.

That is important because the X-Rite 5 step calibration strip costs $95 from X-Rite or roughly ⅓ the price asked for the unit and is needed for calibration.

The unit is used to adjust exposure for printing. The UV mode measures film base fog. New price $3410 from X-Rite

For more detail, here is an article on the Unblinking Eye about Bob Herbst’s use of The X-Rite 361T to determine proper exposure of pyro negatives for platinum printing. http://www.unblinkingeye.com/Articles/Densi/densi.html

This unit was setup in my darkroom by platinum printer Peter Spangenberg. It is working today as you can see in the photo.

Included with the unit: The “Operation Manual”, “Instrument Registration Form”, “Reference Guide” and “Lamp Replacement/ Alignment Instructions”, all for the X-Rite 361T Densitometer.

Price $300 to me plus postage and insurance from Bath, OH 44210 USA

Payment by Paypal as a gift. Paypal as a purchase plus 3%, or Cashier’s check.
No postal money order please. The Bath, OH Post Office is so small it took them five days to accumulate $350 the last time someone sent me a money order.

Oh, John... I'm tooooo late on this one! 10 years too late! I just bought one - like new condition - and I opened the manual and thought to myself - 'self- you're gonna need a class on this!' And so I looked on APUG - that is, Phototrio and lo and behold - my teacher! I may have to come visit! I'm starting out the new year learning sensitometry and BTZS. I think everybody else is up to BTNS by now
Hope you and Dolly and the girls are well!

oops, just read the rest of the post - tripping over enthusiasm again!

The manual makes it seem more complicated.

The 361t is a specialized machine for UV printing, but it will work just fine to do BTZS tests for printing with normal, non-UV light.

If you going to be using it to analyze negatives for alt-process UV contact printing, under COLOR chose "u" "UV", otherwise, for B&W BTZS testing, choose "o" "ORTH".

You can ignore the "+Dot" and "-Dot" , "Reference Base" and "Serial Interface" functions and choose "Den" for density to make your readings.

Did it come with a calibration tablet?

I see the links in John's post are outdated, this is a current link to the PDF manual in case anyone else is looking for it:

Yes, I am using UV printing and BTZS testing (hopefully for UV printing), and yes it came with a calibration tablet. I'm just beginning to learn curve plotting (by hand) and it's going to be a long road. I managed to calibrate it this morning, and decided to ignore the Dots etc, like you said. Thanks for the feedback and hope you are well,
Dorothy

So you are UV printing, you have a good instrument for that!

 

[djkloss]

Yes, AND I have John's old UV light box! Learning Van Dyke Brown now, still learning Cyanotype

John,

You getting out of photography? Hope you are doing well...

I think this thread's been hijacked!

Please note the date of the ad.

I've removed the 'For sale' tag in the assumption that the unit has possibly been sold at some point during the past decade.

Yeah, it's been necro'd... John hasn't been on Photrio in four years.
