One method would be to weigh a desiccant and then expose it to your known target volume to allow it to dry the material. Then re-weigh the desiccant. If your'e looking at a low % of water vapour, you should attempt to minimise the 'tare weight' of your desiccant. Crumbled calcium sulphate is a safe desiccant - just dry it out well beforehand.
