Need a substitute for trident and NP

[JPR1212]

Hello everyone,

I’ve had enough of the trident testers. No matter how many times I get a replacement they always are completely out of calibration within a week. Even with calibration they don’t read accurately. I’m frustrated and tired after losing lots of corals from swings. Anyone have a good substitute for testing alk and cal at the minimum? Would prefer a system that is know to be good with checking alk, mag, ca, nitrate and phos but Im just trying to see what I can find.

I have Kamoer KH carer. It’s been very solid. Minus the first unit being busted. Calibrate it once a month or so and it has been very close to Hannah. Only alk though.
