TEMPERATURE-pH METER, Model : HD2305.0, Brand : DeltaOhm

The HD2305.0 is a portable instruments with a large LCD display. It measures the pH and the redox potential ( ORP) in mV. It measures the temperature using Pt100 or Pt1000 immersion, penetration or contact probes. The electrode calibration can be carried out on one, two or three points at 4.01pH, 6.86pH and 9.18pH. The temperature probes are fitted with an automatic detection module, with the factory calibration settings already being memorized inside. The Max, Min and Avg function calculate the maximum, minimum or average values. Other functions include: the relative measurement REL, the Auto-HOLD function, and the automatic turning off that can also be disabled. The instruments have IP67 protection degree.
