Dear Thank you for choosing a Hanna Instruments product. Please read this instruction manual carefully before Customer, using this meter. This manual will provide you with the necessary information for correct use of this meter, as well as a precise idea of its versatility.
Notify your nearest Hanna Instruments Customer Service Center if damage is observed. Each HI991300 is delivered in a rugged carrying case and is supplied with: •...
GENERAL DESCRIPTION AND INTENDED USE HI991300 HI991301 are lightweight, portable pH, conductivity (or total dissolved solids) and temperature meters for portable applications requiring both pH and conductivity (or TDS) measurement. To increase conductivity accuracy, two models are available, with different conductivity ranges, for applications from purified to brackish waters.
MAIN FEATURES • Simultaneous pH, EC or TDS and temperature measurements on a large three line LCD display • Selectable temperature unit (°C or °F) • pH electrode condition indicator • mV of pH measurement for electrode check • Last calibration points pH and EC •...
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“). CONNECTING THE ELECTRODE With the meter turned off, connect the HI12883 probe to the DIN socket on the bottom of the meter by aligning the pins and pushing in the plug firmly.

- Compatible pH probe: HI12963, HI12943, HI10483 probes and HI763003 EC probe. If one of the probes is detected “NoEC“ message is displayed or if HI763003 connected “NopH“ message is displayed at start-up and “---“ message is displayed on the secondary LCD for the pH probes or on the primary LCD for the EC probe.

pH MEASUREMENT & CALIBRATION Make sure the meter has been calibrated before use. If the probe is dry, soak it in HI70300 storage solution for 30 minutes to reactivate it. If soiled, clean the electrode by soaking in cleaning solution for 20 minutes, then rinse the tip and soak in storage solution at least 30 minutes before use.

is out of the accepted range “---- WRONG“ is displayed. 3. If the buffer is recognized “REC“ is displayed then “WAIT“ until the calibration is accepted. If using pH 7.01 (or pH 6.86 for NIST), after acceptance of the buffer press any key to exit. The ”SAVE” message is displayed and the meter returns to pH measurement mode.

pH ELECTRODE CONDITION The display is provided with a probe icon (unless the feature is disabled from setup) which indicates the pH 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 pH calibration has two points.

Select calibration type “EC STD“ . The meter enters the calibration mode and “μS 1.41 USE” (HI991300) or “mS 12.88 USE“ (HI991301) is displayed with blinking. Immerse the probe in calibration solution. If the standard value is recognized “REC“...
METER SETUP Setup mode allows the selection of the Temperature unit, Auto‑off, Beep confirmation tone, the type of pH buffer set, the pH Resolution, enable/disable calibration information display, temperature compensation factor for EC and TDS conversion factor. To enter Setup mode press and hold button until “EC STD“...

• To switch the electrode condition indicator ON or OFF on the LCD, press the SET button; press confirm and to enter temperature compensation factor “BETA“. • “BETA“ is displayed on the third LCD line with the current temperature compensation factor (e.g. “1.9“), use SET button to modify the value.
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 a few seconds then the meter powers off. Immediately replace the batteries with new ones.
