Any of u guys use the hanna test equipment ? If so how good and what exactly can they detect?
I use the phosphate checker. Spot on.
I use the Alkalinity and the Phosphate one.
The Phosphate one is pretty good, if you remember to times the result by 0.33 to give you the true value.
Have u seen the multi function ones about £120 -140 do u know what Exaclty they measure?
Not seen them tbh do you have a link?
No mate. Went in lfs and he was showing me it. I just wanted to know if it did salinity too
I ve seen the multi function hanna ones, they do ones that also go up to about £500 that do loads of stuff.
I use the hanna phosphate checker and its good as long as the vials are spotless.
Ged- do you mean times the phosphorous checker result by 0.33?
ged is talking about the older phosphorous model, not the new ones.
i use the new phosphate reader gives readings 0.0? ppm phosphate so no further calculating to do. I'm very happy with accuracy too - RowaPhos outflow reads 0.00ppm and tank always reads a little fraction higher.
At the same time we got the new version alkalinity kit with liquid reagant - totally superb - very accurate readings - this one i multiply by 0.056 to get my prefered dkh reading, and down to 2 decimal places too so the tanks requirements for stable alkalinily are very easy to measure.
so far they have phosphorous, phosphate, iodine, chlorine, alkalinity, iron and nitrite pocket testers, all at £41.25
they have many single testers in the waterproof range - from £175-£300+ (unfortunate the nitrate is £300)
the multi test meters vary from £360 to £1000 and can test anything you buy the reagant for to laboratory standard, the cheaper models doing a small selection of tests, the more expensive models doing far more tests. There are meters that can do every test you can concieve needing in the list on their web site, but at a price as they are proper lab models
excelent meters in my opinion, and old fashioned test kits will become a thing of the past in coming years. I've just enquired directly to hanna about saltwater testing for nitrate, calcium and magnesium and will let you know the reply
As I understand it both the phosphorous and phosphate checkers are current, just some people prefer the higher resolution given by the phosphorous checker..
I think there's a lot of people including me waiting for the nitrate checkers Big Thumbs Up
Have a look at the last page on this thread pal
OOOOOO That is interesting! So what ever reading i get on the hanna phosphate checker i divide by 0.33?
Times it by?
0.05 * 0.33 = 0.0165
yeah if you do that all the test kits and the hanna should tally
oh yeah, times sorry.
Phosphate checker is in pp MILLION
Phosphorous checker is in pp BILLION
I personally use the phosphorus checker and the conversion from phosphorus to phosphate is really easy
Phosphorus x 3.066 divided by 1000 gives you phosphate
and + 1Big Thumbs Up on waiting for the nitrate checker
thought that i would bring it to your attenion on the great deal we have in the lattest issue of Marine Habitat in the Snap and Grab section. www.littleocean.co.uk have £5 off the Hanna checkers.
