The OMEGA™ PHH-SD1 is innovative and easy to operate. What sets the PHH-SD1 apart from other pH/ORP meters is that it incorporates a real-time SD card data logger. The PHH-SD1 measures pH or mV (ORP) using standard electrodes with BNC connectors. Download data from the SD card directly into an Excel spreadsheet. This allows the user to do further data or graphical analysis without special software. The PHH-SD1 has a wide variety of applications from water conditioning, aquariums, beverage manufacturing and fish hatcheries to food processing, photography, paper and plating industries, educational and other laboratories.
