|A few pics Of the Ashworth Speedy Moisture tester findable from resellers with a google search at about $1000 or £700 new or on ebay every so often for less.|
You want the one for oils but the main difference is that the oils one uses a syringe instead of a scale to measure the sample. If you find a secondhand soil one I can always pass on the calibration of the syringe for you to duplicate.
The size of the testing chamber also varies and the % moisture calibrated on the dial can also vary and go as high as 50%. That one is for testing concret aggregates.

Can't vouch the numbers will be up to date this was taken from a manual written in the 1980's.
Ahworths invented and developed this method in the 1930's. They are still in business and seem to have an established global niche market. They make other equipment too.This message has been edited. Last edited by: Ant,
