Hi....I have been using the Profilux for about 1 month in a limited fashion. I only have 2 Tunze pumps working on it. I am going to get more serious since I have put together my 4 dimmable ballest and are currently burning in the T5's. I wanted to check the temp probe before hooking up the heaters to the profilux. I borrowed 2 traceable temp probes from work, these are calibrated lab probes. What I found is as follows;
Trace probe #1 = 83.9
Trace probe #2 = 84.2
Profilux = 81.4
Cheap Digital Temp = 80.2
Won Bros. Digital Controller Heater = 84.1
Soooooo what gives.....Profilux is (rounding off) 3 degrees off. That seems alot for a calibrated probe.
Now here is where it gets strange. Removing the probes from the water and using air temp the temps are as follows;
Trace probe #1 = 71.7
Trace probe #2 =72.5
Profilux =69.8
Cheap Digital Temp = 69.4
Won Bros. Digital Controller Heater = (not used since it is controlling the tank)
Now they are all about 1 - 1.5 degree off.
The traceable temp probes are + or - 1 degree nominal deviation.
I can post the certificate data on the traceable probes if anyone wants to know. I'm posting this as infomation only for what its worth. Its been some time that I have been into the profilux interface software and I think I can set an offset, if I remember correctly, so no big deal. I'm still setting up this tank.
