TPW 97% at 18.8* with FSD 4" & 500ml pack col

[paleale]

Hi all its been a long time between runs (nearly 2yrs :crying-blue: ) This is my 1st TPW in a long time and I'm just wondering if what I'm seeing is correct. I'm getting 97% at 18.8 degrees from my FSD 4 bubble plate, with a 500ml pack section with 1kg of copper mesh.
On my old set up using the plumbed in water pump and rain tank I was only ever able to get around the 94% at 20 degrees using the same thermometer. I'm just wondering what % other people with a 4" FSD Neutralizer are getting as this is basically what I have minus 1 bubble plate modal.

Cheers for your expertise :handgestures-thumbupleft: ,

Think 95% or 96% is about max you can get without some special gear like vaccum stills or adding benzine to your wash??

Thanks for the heads up, it must be this Alcolmeter, tho its still the same one I used back when I was in NSW. Can they change readings over time?

Think the little paper reading gauge inside can slip sometimes. Maybe put it in some water at 20*c and see if it reads zero?

Also look for any small cracks as it'll absorb moisture putting out your readings.
