Page 4: Preliminary Examination
Remove the meter from the packing material and examine it carefully to make sure that no damage has occurred during shipment. If noticeable damage is evident, contact your local Hanna Instruments Office. Each meter is supplied complete with: • HI629113 preamplified pH probe with built‑in... -
Page 5: General Description And Intended Use
HI99131 portable pH meter, together with the HI629113 pH probe, are designed specifically for pH measurements in plating baths. Plating Baths can vary from acid to neutral to alkaline with many different chemical formulations used. The common necessity is the fast and... -

Page 9: Operational Guide
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“). TO CONNECT THE ELECTRODE With the meter turned off, connect the HI629113 probe to the DIN socket on the bottom of the meter by aligning the pins and pushing in the plug firmly. - Page 10 TO SELECT THE MEASUREMENT RANGE While in measurement mode, press the SET button to select pH or pH‑mV measurement on the first LCD line. TO FREEZE THE MEASUREMENT VALUES While in measurement mode, press and hold the SET button until “HOLD“ appears on the secondary LCD. The “HOLD“...
- Page 11 The LCD displays the pH value (auto‑ matically compensated for tempera‑ ture) 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 † to eliminate cross‑contamination. For better accuracy, frequent calibration of the pH sensor with the meter is recommended.
- Page 12 If using pH 4.01 or 10.01 (or pH 9.18 for NIST) buffer the ”SAVE” message is displayed and meter returns to pH measurement mode. Two-point calibration Proceed with steps 1 through 3 under single point calibration using 7.01 (pH 6.86 for NIST) pH buffer first. Then follow steps below: The ”pH 4.01 USE”...
- Page 13 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.

Setup mode allows the selection of the Temperature unit, Auto‑off, Beep, 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 tag. Release the button. •... -
Page 15: Battery Replacement
BATTERY REPLACEMENT When the remaining battery life is less than 10% the battery tag blinks on the display to warn the user. Battery Error Prevention System (BEPS) If the battery is too weak (“0%”) the display shows “bAtt“, “DEAD“ for few seconds then the meter power off. Immediately replace the batteries with new ones. -
