Dissolved Oxygen Meter - FAQ Section
Q: How often should I calibrate my dissolved oxygen meter?
A: For optimal accuracy, we recommend calibrating your dissolved oxygen meter before each use or at least once per day when in regular use. The instrument features a calibration reminder function. Calibration frequency may increase in demanding environments with extreme temperatures or high organic loads.
Q: What maintenance does a dissolved oxygen meter require?
A: Our optical dissolved oxygen meters require minimal maintenance compared to traditional polarographic sensors. Regular care includes rinsing the sensor with clean water after use, periodic verification with standard solutions, and ensuring the protective cap contains sufficient storage solution when not in use. The sensor membrane should be replaced approximately every 12-18 months under normal use conditions.
Q: Can this dissolved oxygen meter be used in saltwater applications?
A: Yes, our dissolved oxygen meter features automatic salinity compensation up to 50 ppt (parts per thousand), making it suitable for both freshwater and marine environments. The salinity compensation function adjusts readings based on the dissolved salt content to ensure accurate measurements across different water types. For best results in marine applications, we recommend performing calibration in conditions similar to your measurement environment.
