Hanna Checker HI70023 5.00ppt Salinity Calibration 20ml

Care & Maintenance

It is recommended that you calibrate the electrode before using. For best results, calibrate frequently. Additionally, the instrument must be calibrated:

• - When high accuracy is required
• - At least once a month with regular use

To ensure accuracy with measurements:

• - Use fresh calibration standards for each calibration
• - Rinse the tester with purified water and dry off with a soft tissue before calibrating or taking measurements
• - Calibrate monthly with regular use or more often with frequent use
• - Inspect the tester to see if any foreign material is detected in the openings housing the electrodes
• - A more thorough cleaning may be made using a non-abrasive detergent, and a soft material such as cardboard, to dislodge the material
• - Rinse thoroughly with a stream of running tap water and jetting the stream through the opening. Shake excess water and rinse with purified water. Dry off and recalibrate the tester before using
• - Store with the protective cap on

Check the instrument manual for guidance on how to enter calibration mode and use the calibration standards as instructed.
