Probe positioning

[Psychographic]

Is there a proper positioning of probes as far as distance to one another?

I have an AC Jr. and a Milwaukee ORP controller, and have all three probes (in order, OPR. PH, Temp) mounted next to each other in a DIY eggcrate mount. will having then so close create any interferance?

For the jr and AC3 you should keep the PH and ORP 6" or mode apart; there is no limit on placement of the temp probe; it can be next to any of the probes. For the Pro the PH and ORP need to be less than 6" from the temp probe.
