Alkalinity meter/probe?

[KK's Reef]

Other than an Apex and other multi-function monitors, are there any devices available out there that just measures alkalinity? The thought process here is to be able to check the alkalinity level easily with a device vs. having to test.

To my knowledge, an alkalinity probe does not exist. Closest thing would be KH Director, Trident, Alktronic, etc…

I use the Hanna Alk checker and it’s pretty painless. I can run a test in 2 minutes, maybe less.

Measurement devices measure a physical property. For example ph might be millivolts between 2 probes or salinity might be conductivity. These are analogs for the actual parameter.
We would have to find a measurable property that is an analog for alkalinity.

Agree. I have the Hanna also and it's a pretty simple test. But testing daily, every other day, or every few days can be a bit of a hassle at times.

Understood. Explains the need for the reagent.

Fair enough. I don’t have any experience with the automatic testers but if I did buy one it would be the Trident. I’d love the Mastertronic but it’s a lot of money.

One of the first automatic devices to be created was a small tile that went in the tank and had replaceable discs. I believe it would give you real time numbers but it never made it past prototype. I believe Neptune actually purchased the patent from the developers.

Reagentless Acid–Base Titration for Alkalinity Detection in Seawater - PMC

Herein, we report on a reagentless electroanalytical methodology for automatized acid–base titrations of water samples that are confined into very thin spatial domains. The concept is based on the recent discovery from our group (Wiorek A.et al. ...
