From Wetzlar Germany, density measurement for the no-nonsense professional - at very affordable prices. Solid, no-frills densitometers that are highly accurate yet simple to use. Compact and robust, they are made to withstand years of darkroom and laboratory use. There are versions to suit every densitometric requirement - all of them based on a single well-proven platform.

All of these instruments are fully equipped densitometers, with every component optimally adjusted. Each unit is calibrated according to stringent parameters and adjusted to well tested references - and will stay that way for a very long time.

“I cannot overstate how strongly both my wife and I feel about the rock-solid comfort we have in dealing with Versalab. Our congratulations on work, integrity and business being done as it should be!” John L. Webb

To use the Heiland densitometer is extremely simple - zero the base value, insert the sample, read the density - as simple as that.
