Portable Dissolved Oxygen Tester 25-PDO101

Portable Dissolved Oxygen Tester 25-PDO101 is equipped with polarographic sensor to measure the dissolved oxygen content. The manual salinity & barometric pressure compensation helps in accurate measurement of dissolved oxygen. The system menu of dissolved oxygen meter can set 9 parameters such as stability conditions, calibration points etc. Due to its portable nature this meter can be used across water purification plants, waste water management plants for testing & quality analysis.
