    "Who makes this unit????does this unit self adjust for differant water temperature????"

    • A:

      Thank you for your question, larry4444444. We are unable to disclose the manufacturer of some of our products; however, stands behind every product we sell. When necessary we can contact suppliers if a product issue arises. The Total Dissolved Solids (TDS) Meter does not self adjust for different water temperatures. For best results, 25 degrees Celsius is the ideal temperature for conductivity readings. Have a great day.
