The waterproof pH meters (pH55 PRO, pH56 PRO, pH58 MAX, ORP57 PRO) are equipped with a two-level LCD display that, depending on the meter, shows the pH, temperature (ºC or F) or redox value. The meters have a stability indicator and a stop function for easy and accurate data reading. The pH58 MAX model allows simultaneous measurement of pH and redox. Calibration is automatic, 1 or 2 point with stored sets of reference buffers.
The pH51 and pH54 meters have a wood-tight housing and a replaceable electrode with a double connector, which also makes them suitable for applications such as wastewater treatment plants. Manual calibration extends battery life to 1,500 hours.
The modular design allows easy electrode and battery replacement.
