It's designed as a reading tablet with good pen support, so yes. And E-ink makes reading more comfortable than LCDs. For technical PDFs, size matters a lot. Normal reading tablets often resize the text to be easily readable, but PDFs cannot do that. So having a tablet of good size becomes a dealbreaker for such use-cases, more so than other features. Remarkable lacks a backlight, and e-ink displays don't have deep blacks, so depending on your reading environment, it may be a bit low-contrast. I got a kobo elipsa myself for this reason. Kobu is notably cheaper and has a backlight which helps the contrast a bit, but the pen support is waaay worse.
