Overview
HANNA HI99171 Waterproof Portable pH Meter is an instrument designed for acidity-pH measurement analysis of samples from surface, leather, paper, emulsion industries, etc. It has an LCD large screen display, which can easily view pH, pH-mV, temperature measurement readings and instrument performance status from multiple angles; Built-in Sensor Check ™ function allows users to check Electrode status at any time; Flat-head Glass acidity pH Electrode with built-in amplifier and temperature sensor is rugged and IP67 waterproof. Portable two-button design for quick setting and calibrating, providing accurate measurement results for professional research and production.
Features
pH range: -2.00 to 16.00pH; pH-mV conversion: +/- 825 mV
2. Automatic one or two point calibrating, built-in two sets of standard calibrating points
3. With Sensor Check ™ function, allowing users to check Electrode status at any time
4. Built-in amplifier and temperature sensor Glass acidity pH Electrode
5. Stable logo design, when the reading reaches stability, the stable logo will disappear
6. Press the HOLD key to lock the display screen reading, which is convenient for recording measurement results
7. BEPS (Battery Error Prevention System), when the battery is lower than 5%, the battery symbol on the LCD flashes to indicate that the battery is low
8. Automatic shutdown setting, the instrument automatically shuts down after 8 minutes of not using, prolonging Battery life
Principle
The HANNA HI99171 Waterproof Portable pH Meter takes measurements with a flat-head Glass acidity pH Electrode with built-in amplifier and temperature sensor. The automatic temperature compensation range is -5.0 to 105 ° C, ensuring accurate pH and temperature readings at different temperatures. The instrument uses Automatic calibration and Sensor Check ™ functions to monitor Electrode status in real time, providing stable measurement results.
Applications
Surface, leather, paper, emulsion industry
Steps
1. Turn on the instrument power
2. Use two buttons for quick setup and calibrate mode
3. Electrode immersion in the sample for measurement
4. Press the HOLD key to lock the display reading to record the result
5. The instrument automatically shuts down after 8 minutes of not using it
Notice
• Operating Environment Temperature 0.0~ 50.0 ℃
• When the battery level is lower than 5%, the battery symbol on the LCD will flash, and the battery should be replaced in time
• The automatic shutdown time of the instrument is 8 minutes to extend the Battery life
• Make sure Electrodes are properly connected and cleaned to maintain Measurement accuracy
