Our new series of portable waterproof instruments offer measurement in pH, pH/ORP and pH/ORP/ISE with our exclusive Calibration Check™ and with 5 point calibration . These instruments recognize 7 memorized buffers and up to 5 custom buffers. The large, backlit LCD displays calibration messages and features an electrode condition graph which alerts the user of electrode status. Users can set a reminder of when calibration is due. These meters are equipped with auto-end measuring mode that ensure readings are only taken when they are stable. If measurements are taken to far outside the calibration range, the instruments will warn the user with graphic symbols.
