Nitrate Testing Meter/Probe?

[Aspect]

Hello, does anyone know if there is a Nitrate Meter/Probe out there? All of the other parameters I need tested are automatic, so I'm trying not to buy a whole test kit just to check for nitrates.

Nothing reliable available in North America.

Only one is the mastertronic. Kinda pointless to spend $1300 to automate nitrate testing though.

There are ISE probes available but they come with a lot of calibration and ion interference bagage.
This is the cheapest one that I am aware of but you need to be associated with an edu to purchase from them.

Edit:
Here is a Bluetooth model that may be easier to use for most.

The bluetooth model would work best for me, although I am not associated with a school.

Unless you set up something like a raspberry pi, this would not be automated tests. You would need to keep it in storage solution, regularly calibrate, and place in tank and set up Bluetooth app to read. There is a good chance this won't actually save you any time.

With my Hanna HR nitrate checker, it takes me 1 minute to add water, cut packet, shake vial, wipe vial. Then wait 3 minutes and the reading is ready.

Before you get a nitrate probe, you would need to verify with vernier that none of the materials used in the probe can be corroded by saltwater and leach something back into the tank.
