Principle
The HANNA HI99121 performs pH measurement with a built-in HI1292D Glass composite acidity pH Electrode with a built-in temperature sensor that supports automatic temperature compensation. The instrument automatically recognizes two-point calibrated and calibrates with built-in standard calibrated points to ensure Measurement accuracy.
Applications
Agriculture, landscape, soil industry
Steps
1. Turn on the instrument power.
2. Carry out two-point calibrating according to the prompts, and automatically identify the calibrating points.
3. Immerse the Electrode in the sample to be tested.
4. Read the pH and temperature values displayed on the screen.
5. Clean Electrode after use, and automatically shut down after 8 minutes of no operation.
Notice
• Make sure the battery is fully charged to avoid measurement errors caused by low battery.
• The ambient temperature range is 0.0~ 50.0 ° C, Humidity maximum 100% RH.
• Follow instrument cues when calibrating and measuring.
• Electrode status is checked regularly to ensure measurement accuracy.
• The instrument needs to be restarted after automatic shutdown.
