Hanna Instrument PH Tester Hanna Instruments

• The HI98108 tester features a large multi-level LCD which displays both pH and temperature readings simultaneously.
• The pH readings are displayed with a 0.01 pH resolution and with an accuracy of ±0.10 pH.
• The pH range of the HI98108 is from 0.00 to 14.00 pH.
• An exposed temperature sensor allows for rapid automatic temperature compensated pH measurements.
• Temperature can be set to display in ℃ or ℉.
• The LCD screen has stability and calibration tag indicators.
• The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.
• The pH electrode uses a unique reference cell design that utilizes an extractable cloth junction.
• A clogged junction will typically exhibit erratic readings that will not stabilize.
• Simply extracting a small portion of cloth from the meter will clear any clog by exposing a fresh, clean surface. 
• The ability to clear any clogging will extend the life of the pH electrode.
• Calibration is performed by pressing the dedicated calibration button.
• Once in calibration mode the pH electrode can be calibrated to 1 or 2 points using the pre-programmed standard buffers (pH 4.01, 7.01,10.01).
• When the standard value is recognized and stability is reached, the meter automatically accepts and stores the calibration value.
• Setup options include automatic shut off timing and temperature unit displayed.
• Automatic shut-off options are to turn the meter off after 8 minutes, 60 minutes, or disabled.
• To enter the setup mode the user presses a button located in the battery compartment.
