Multiparameter Testers

Many applications require a pH/EC, pH/TDS, or pH/ORP measurements. The pH/EC/TDS parameters are commonly measured in agriculture, including hydroponics and greenhouses, printing industry fountain solutions, and basic water quality including boiler and cooling tower treatments. The measurement of both pH and ORP is important in spas and swimming pools, food disinfection, and plating wastewater treatment. Our COMBO® meters feature a multi-level LCD that displays both temperature and the parameter of interest but also has indicators for instability, calibration, and battery level.
