I have the hi713 phosphate meter, would need new reagents as they expired, but other wise in great shape w box and instructions, 20.00

Wanted the phosphorous one due to low range capabilities. What are your thoughts about the phosphate one? Does it give accurate low range readings?
Thanks!

Brs did a good comparison...phosphorous won hands down.

Where are you located? I have Alk and Ulr that I don’t use.
