PRELIMINARY EXAMINATION PRELIMINARY EXAMINATION Remove the instrument and accessories from the packaging and examine it carefully to make sure that no damage has occurred during shipping. Notify your nearest Hanna Instruments Customer Service Center if damage is observed. Each HI99181 is delivered in a rugged carrying case and is supplied with: • HI14143/50 pH/temperature probe with flat tip, DIN connector and 1m (3.3') cable • HI700620 Cleaning and disinfection solution for skin residuals (1 sachet) • HI700621 Electrode cleaning solution for skin grease and sebum (1 sachet) • Instrument quality...

The HI99181 portable pH meter together with a HI14143/50 combination pH electrode, is designed to measure pH on skin and scalp. The HI99181 features a two button operation system and is simple to use. It has a waterproof and compact casing, large dual-line display, and automatic pH calibration at one or two points. The HI14143/50 has a built-in temperature sensor for temperature compensated pH readings and an integrated preamplifier to provide measurements impervious to noise and electrical interferences. The flat tip of the HI14143/50 provides optimal contact between the sample and the sensor....

MAIN FEATURES MAIN FEATURES • Simultaneous pH and temperature measurements on a large dual-line LCD display • Automatic pH calibration at one or two points within two memorized buffer sets (standard or NIST) • Selectable temperature unit (°C or °F) • Electrode condition indicator • mV of pH measurement for electrode check • HI14143/50 dedicated pH probe with integrated temperature sensor • Probe quick connect system • Battery life indication and low battery detection • Keystroke confirmation tone • Auto-off function

the HI14143/50 is limited to be used from 0 to 12 pH and from 0 to 50 °C temperature (32 to 122 °F)

DISPLAY DESCRIPTION DISPLAY DESCRIPTION 1 Automatic Temperature Compensation indicator 4 Electrode condition indicator 10 Meter modes indicator 11 pH calibration buffer(s) used

Each meter is supplied with batteries. Before using the meter for the first time, open the battery compartment and insert batteries, observing the polarity (see “Battery Replacement“). CONNECTING THE ELECTRODE With the meter turned off, connect the HI14143/50 probe to the DIN socket on the bottom of the meter by aligning the pins and pushing in the plug firmly. Remove the protective cap from the probe before taking any measurements. TURNING THE METER ON To turn the meter ON, press the button on the front of the meter. If it does not turn on, make sure that the batteries are properly installed...

OPERATIONAL GUIDE SELECTING MEASUREMENT RANGE While in measurement mode, press the SET button to select pH or pH-mV measurement on the first LCD line. FREEZING MEASUREMENT VALUES While in measurement mode, press and hold the SET button until “HOLD“ appears on the secondary LCD. The “HOLD“ remains for 1 second and reading of pH, mV and temperature will be frozen on the LCD with “H” blinking. → Press any button to resume active measurements. ENTERING CALIBRATION MODE tag Press and hold the button until ”POWER” and is replaced by “STD“ and tag. Release the button. ENTERING SETUP MODE tag is Press...

The LCD displays the pH value (automatically compensated for temperature) on the primary LCD, while the secondary LCD displays the sample temperature. If measurements are taken in different samples successively, rinse the probe tip thoroughly in distilled or deionized water to eliminate cross-contamination. For better accuracy, frequent calibration of the pH sensor with the meter is recommended. In addition, the meter must be recalibrated: a) whenever the pH electrode is replaced. b) after testing aggressive chemicals. c) when high accuracy is required. d) at least once a month. OPERATIONAL GUIDE...

Two-point calibration Proceed with steps 1 through 3 under single-point calibration using 7.01 pH (pH 6.86 for NIST) buffer first. Then follow steps below: The ”pH 4.01 USE” message is then displayed. Place the probe in the second calibration buffer (pH 4.01 or 10.01, or, if using NIST, pH 4.01 or 9.18). When the second buffer is accepted, the LCD will display “SAVE” for 1 second and the meter will return to the normal measurement mode. If the buffer is not recognized or the slope is out of accepted range ”--- WRONG” is displayed. Change the buffer, clean the electrode or press any key to exit...

OPERATIONAL GUIDE ELECTRODE CONDITION The display is provided with a probe icon (unless the feature is disabled from setup) which indicates the electrode status after calibration. The “condition” remains active for 12 hours (unless the batteries are removed). The electrode condition is evaluated only if the current calibration has two points. 5 bars: excellent condition 4 bars: very good condition 3 bars: good condition 2 bars: fair condition 1 bar: poor condition 1 bar blinking: very poor condition With 1 bar it is recommended to clean the electrode and recalibrate. If there is still only 1...

METER SETUP METER SETUP Setup mode allows the selection of the Temperature unit, Auto-off, Beep confirmation tone, the type of pH buffer set, the Resolution and Information. To enter Setup mode press and hold button until "STD" and tag is replaced by "SETUP" and EEHl tag. Release the button. • "TEMP" is displayed on the secondary LCD with the current temperature unit (e.g. "TEMP °C"), for °C/°F selection, use the SET button. After the temperature unit has been selected, press 4? to confirm and to enter the "A-OFF" selection. • Use the SET button, to navigate through the auto-off choices: 8 minutes...
