便携式手持多参数水质仪
Field technicians taking spot readings at many sites want one handheld for pH, conductivity, DO, ORP and temperature. This IP67 meter auto-ranges conductivity to 200 mS/cm, reads ORP to ±1 mV and stores 5,000–50,000 records. Probe cables come in lengths from 1 to 30 m, so let us know your sampling depth.
