pH probes

[Steve Burton]

I'm going to set up a calcium reactor and I need to order a ph probe. I am looking for double Junction lab grade, just wondering if anyone has any opinions on what is better. I'm considering Milwaukee and BRS so far. Thanks

I've had great luck with Atlas Scientific - I still have 2 that work and hold calibration - even when I'm a knucklehead and have let them dry out.

Thanks Leo, got one ordered. A few more dollars than Milwaukee or BRS. I was impressed that they actually list time before calibration as 1 year and life expectancy as 2.5 years That and your recommendation convinced me.
