Overview
Agro Enviro Tests Portable Oxygen Meter features a built-in microprocessor for intelligent functions like automatic calibration, temperature compensation, data storage, and more. It’s a double-parameter meter with pH and dissolved oxygen electrodes, automatically identifying the electrode type. It also recognizes 13 pH standard buffer solutions and offers various options. You can even set pH measurement modes for high purity and pure water with ammonia. The dissolved oxygen mode includes temperature, salinity, and manual air pressure compensation. The polarographic-type electrode measures all three parameters simultaneously, with quick polarization in just 3 to 5 minutes. This IP 57 waterproof meter comes with calibration solutions and a portable case for convenience.
