Description
EziLab offers the Compact Dissolved Oxygen Meter EZL-CDO121, a portable DO meter reading 0 to 20 mg/L through a polarographic electrode that also tracks temperature and salinity. Automatic temperature, salinity, and pressure compensation correct readings, and auto-calibration with a calibration sleeve gets the probe ready after 3 to 5 minutes of polarization. A backlit LCD, 200-set data storage, and auto power-off fit a 360 g IP57 housing run on two AA batteries. Screw-on membrane caps replace the sensing membrane with a simple twist, and the anti-slip, impact-resistant shell survives field handling, so this dissolved oxygen tester suits stream banks, pond edges, and treatment plant walkways. Technicians log readings on site instead of carrying samples back, avoiding oxygen loss in transit. Three spare membrane caps, electrolyte, and backup batteries ship with the kit. Aquaculture farms check fish ponds and tanks to prevent oxygen crashes, while water utilities monitor source water and aeration basins. Sewage treatment plants track dissolved oxygen through biological stages, and environmental protection agencies survey rivers and lakes. As a handheld dissolved oxygen meter, it gives field crews and teaching labs a light, waterproof option. See the Dissolved Oxygen Meters and Compact Dissolved Oxygen Meter pages for full specifications.
