PeakTech 5307 PR - Replacement Electrode for PeakTech 5307

4-in-1 Meter for pH, Electric Conductivity (EC) , Total Dissolved Solids (TDS), Temperature This 4 in 1 meter with one-hand operation measures: - The pH value of liquids via the galvanic voltage difference between acidic, neutral and basic liquids; - The conductivity EC in µS/cm is via two electrodes on the sensor head; - The TDS value for the total dissolved solids;. - The liquid temperature, displayed simultaneously on the second line of LCD display that is permanent backlight. Attached to the sturdy and waterproof housing is the easily replaceable sensor head, which includes the sensor for PH/EC/TDS and Temperature measurement.
