Speedy® 2000 Moisture Tester
The Series 2000 Speedy® moisture tester is a portable system for measuring the moisture content of a wide range of materials including soils, aggregates, dust and powders (and liquids).
The system consists of a low pressure vessel fitted with a pressure gauge and an electronic scale and test accessories. Moisture measurements are made by mixing a weighed sample of the material with a calcium carbide reagent in the sealed pressure vessel.
The reagent reacts chemically with water in the sample, producing acetylene gas that in turn increases the pressure within the vessel.
The pressure increase in the vessel is proportional to the amount of water in the sample, the moisture content can be read directly from the calibrated pressure gauge.
The Speedy has an accuracy of 0.5% on most materials and the gauge can be calibrated from 0-20% moisture,
purchase a Speedy 2000 Moisture tester here:
prices start at $1,259
Might as well buy a KF for the price they are charging!
I built my Carbide Moisture Tester for about $12.59
On the other hand, there is this home made tester that appears to be every bit as good as the $1259 version for about total cost roughly £20 ($27)
As a bonus this kit will work with calcium hydride/ CaH2 (karl Fischer) and calcium carbide/ CaC2 (Speedy 2000 Moisture tester)
I completely forgot about the Biopowered version. Good find Tilly, on both posts.
The $1200 version does go to proof of concept for both the British and Irish versions.
