Factory calibrated and shipped in a specialised storage chamber, these electrodes will hold their calibration to +0.10pH units for one year
The Orion No Cal pH electrode, models 51-07 and 51-09, are said to be the worlds first electrodes that do not require daily calibration.
Factory calibrated and shipped in a specialised storage chamber, these electrodes will hold their calibration to + 0.10pH units for one year.
Giving quick and accurate readings, connect it to the waterproof portable Orion meters to give an ideal system for field measurements.
No need for clumsy calibrations, no need to carry standards, simply remove the electrode form it's storage chamber, place it in your sample and measure.
