Replacement Ph Electrodes ? where to get them ?

[rainbow]

I am currently using Aqua Medic Ph controller and am after a replacement electrode. Anyone know where to get them for a reasoable price (ie, under $100) ? My controller has regular BNC connection. I have only ever used Aqua medic brand of Ph electrode and have found them to be very accurate and long life (2 years). Thanks in advance

I was able to find this one:


Glass Electrode
With double layer
Aquarium and fish farming use
Measuring range: 0 – 14 pH
Temperature range: 0 – 60 C
Zero point value: 7 +/-1 pH
Size: Dia. 12 x 160mm

$63.59

but I am not even sure if this has BNC connection ?

As far as I know all except the bodgy Eheim Ph COntrol sytem have BNC connection. In fact I have an Eheim one you can have if you want to change the cabling with some Dick Smith gear. Also some online medical/surgical supply catalogues list them.
