Delta Ohm


Add to wishlist

The HD2305.0 is a portable ph meter 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.
