Im sure that its the same technology in the singles thats in the dual.Originally Posted by SRMD94
i dont have the dual one like hydro and temp together i have two separate ones if you have the dual one?
I am also from the UK so half of the things people suggest are not available in this country
Take the hydrometer out and perform a test. Google how to calibrate a hydrometer and follow the easy steps. You wont be able to calibrate yours but you will be albe to see if it is close to what it should be.
Or an easier way is if you have a cigar shop near you they sell calibration kits that are set at 70% so you would know for sure that you were testing it right and see if your gauge is right. They are cheap.
If your gauge is not working right you can change your whole tank but it will still be wrong. My tanks each have a digital themometer and a analog temp/humi gauge, and I just added a weather station montior to my tanks. I tend to over prepare. I just posted the station I bought, here is what I got. Not really what you need but will point you in the right direction. http://www.boaphileplastics.com/rhin...ball_room.html
When I first bought the ExoTerra gauge I was freaking out too because no matter what I did it still said low numbers.
Bottom line is TEST IT!!!!
