556MPS
The YSI 556 MPS (Multi-Probe System) is a handheld unit with a multi-parameter system. It simultaneously measures dissolved oxygen, conductivity, temperature, and optional pH and ORP. The 1.5 MB memory can store more than 49,000 data sets. Other options include a flow cell and barometer. The internal barometer can be user-calibrated and displayed along with other data, used in dissolved oxygen calibrations, and logged to memory for tracking changes in barometric pressure. Older and more expensive than the ProPlus and it does not measure for ammonium or nitrates.
