Did a search on the forum on subject. Only Found Frank Cowherd's talk on meters.
I need by the end of the week recommendations for the best sub $100 test meter to send down to the Project Amazonas Santa Cruz Rainforest Preserve for a fish survey to be conducted -- will include looking at fish on the land purchased a few years ago with donations made to the PVAS Foundation, Inc.
Need obviously pH, TDS and Temp if possible in one very durable instrument for field work in the jungle.
Thoughts please soonest as I need to order and have delivered to New Jersey by Thursday next week.
Thank you both.
