Hanna* Dissolved Oxygen Meters


All Hanna dissolved oxygen meters are supplied with a polarographic probe which will take measurements accurate to 0.3 ppm in minutes. All meters can be calibrated in saturated air to one point, without the need for chemical solutions and feature automatic temperature compensation. Operates on four 1.5V AA batteries (included). Model HI 9142 has a rugged, waterproof housing for use in the field. Models HI 9143 and HI 9145 provide readings of O2 (% or mg/L) and temperature. HI 9145 additionally supplies compensation of salinity and altitude factors. A 12V DC adapter allows for continuous use. Model HI 91410 with built-in printer is designed for continuous monitoring and recording at selectable intervals. It prints date, time, sample number, mg/L O2 and temperature. Its memory allows up to 8000 readings to be stored for retrieval at a later time. In addition to ATC, it automatically compensates for altitude from 0 to 1900 meters (6230 feet) and salinity from 0 to 40 g/L. Auto shut-off after four hours. A 12V DC adapter allows for continuous use.
