Hi Hanna,

Do you all have meters that can feed into an arduino for continuous/long-term data collection?

Yes, we have controllers and transmitters with 4-20mA output as well as probes with BNC connections that you can attach to your Arduino.

Hi,
What do you recommend for Portable Multiparameter for on the fly but Pro.
I know of some older Hanna 3 in 1 but I looking for the latest and greatest with a fast and accurate probe that does soil, roots, solutions, and light proteins.
pH probes have changed for the better and time is $.

A single portable unit that I can check soil pH and the EC of the ground and Temp if possible.
It’s for dirt and soilless looking for durability as well.
Also, auto shut off not so good when taking samples after 5 mins like my current meter is from another manufacture.
Depending on volts of the meter I use Lithium Phosphate rechargeable batteries if at all possible instead of 1 time batteries.
