The likelihood of someone having that is low. Why don't you review it, if you end up purchasing it?

I'm put off straight away by the lie "6 in 1". At best it seems to measure three parameters, TDS/EC, temp and pH. Just because it can measure/display these things on different scales (e.g. *C or *F) doesn't mean anything.

Not had that product but similar. The main issue with these multi testers is the quality of the probes…reduce quality to get $ competitive in replacement of accuracy, and what good is a tester if it's not accurate. Ive changed the probes on my PH controller, to better quality probes, and although the readings are more accurate and last longer, I still rely on my 2 x TDS and 1 x PH pen for accurate readings. As these probes remain int he water 24/7, algae/dirt get stuck on them, and they may give a false reading, BUT they are useful if maintained properly, as they can show fluctuations…etc, and be used as a "overall" indicator if the WP decides to go ^!$&!*.

To good to be true and it is, most of my equipment will measure one or two things max, I would be sceptical of some thing like that measuring so many things, but it depends on how accurate you need or want to be?

To give you an idea and Ben will back this, some of the testers I borrow to take into the field cost $600 or more and test 1 thing, I use some of my cheap stuff at the same time and a lot of the time there is a big difference in the readings. I know I am ranting, in a nutshell NO

Sorry for late reply. Thank you all for input and suggestion. i think i will go with separate digital meassurement instead :) I agree a think all in one thing its doesnt seem accurate. after all this cheap product, cant rely on the quality

[northboy]

I think its a good idea, I have seen good ones that test 4 things, but they were 800 bills

We use a multiprobe at work HOWEVER the controller cost $3000 and each probe is worth $300-600. Even then we still get a dud probe arrive that will give false readings and not calibrate properly. Not to mention the probes have to be constantly calibrated to maintain their accuracy. Its not worth it for hobbyists, just stick with cheaper one parameter equipment as all you are really looking for is a major change in a water parameter that is indicative of a problem that will be solved by doing a water change.

Well said Professor Ben and I mean that as a complement Ben. You would be looking for spawning prompts wouldn't you? like the thermal shock that gets the Blue Mussels going

Forgot to tell you Matt we went sole searching with, has a Neritina snail spawning in his Gar pond= full life cycle in fresh YES.

More so for precise measures of pH, salinity, temperature, DO to make sure our treatments in experiments are actually what they are supposed to be. For example we manipulate pH by adding CO2 to study the effects of future ocean pH conditions, so we need to know accurately what the pH is in our seawater systems.

Which neritina? Does it have a nice shell?

[northboy]

Very nice and I have a few of the Limpet types up to 3cm now, so that is the first one off the rank to play with.

I will send you a email about it
