I operate a mobile reproductive consultancy and often perform analyses at client sites. The SDM 1’s dual power options and sturdy construction make it my go-to device. Just pop in the cuvette, press analyze—done. It’s streamlined my entire workflow.

Equipment that costs thousands better add real value—and this does. Given the strong build and automatic calibration, it’s an investment that will easily pay for itself over years of canine and bovine semen analysis. Portable enough to move between barns and the office.

It’s rare to see a lab tool that’s as straightforward to clean as it is accurate. No dilution means fewer steps and less mess, and the LED light keeps things stable—no drift like older models. Well-suited for both field use and more controlled lab work.

Running both a kennel and a small clinic, I needed something versatile yet easy to use. The ability to calibrate for canine, porcine, equine—you name it—makes this device invaluable. Battery operation means I can take it right to the animal, even in outdoor pens.

I rely on precision tools for semen analysis, and this photometer delivers every time. The multiple readings per sample and automatic averaging give me confidence in repeatable, reliable data—especially useful during high-volume days. Calibration on the fly is a huge benefit.
