  • Page 4: Introduction

    Instruction Manual pH 5+, pH 6+, Ion 6+ 1. INTRODUCTION Thank you for selecting our pH 5+, pH 6+, or Ion 6+ portable meter. This microprocessor-based handheld instrument is both economical and easy to use. The pH 5+ measures pH and temperature ( The pH 6+ and Ion 6+ measure pH, mV (ORP) and temperature ( The Ion 6+ can also measure direct ion concentration of various ions (mono and divalent) using an ion selective electrodes (ISE).

    Instruction Manual pH 5+, pH 6+, Ion 6+ CALIBRATE: Press to begin calibration of the selected mode. Press again during calibration to abort calibration and return to measurement mode without confirming any values. During setup mode, function is similar to “escape” or “go back”, returning to the previous screen.

    Instruction Manual pH 5+, pH 6+, Ion 6+ Connecting Electrodes and Temperature Sensor Align the BNC connector slots with the posts of meter’s socket and rotate connector clockwise until it locks—do not force. To remove, rotate the connector in counter- clockwise direction until it unlocks, and slide the connector off the socket.

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3. CALIBRATION 3.1 pH Calibration The 5+ and 6+ meter is capable of calibrating up to 5 pH values using the USA or NIST buffer groups, or 2 pH values using the Low Ionic buffer group. All new calibration values will automatically override existing calibration data.

    Instruction Manual pH 5+, pH 6+, Ion 6+ Resetting User Calibrated Values The meter can be completely reset to factory default values, or partially reset for calibration values only using the procedure below. Reset Type Description No reset is performed; meter returns to measurement No () Reset of either pH, mV, Ion, or Temperature calibration Calibration ()

  • Page 13: Ion Calibration (Ion 6+ Only)

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3.2 Ion Calibration (Ion 6+ only) Ion measurement requires an ion selective electrode (ISE)—sold separately. An ISE will measure one specific ion of interest—such as ammonia or fluoride. The available calibration values for the Ion 6+ are 0.1, 1.0, 10.0, 100.0, and 1000 ppm. Choose any 2 or 3 consecutive values to use and prepare the corresponding ion calibration solutions.

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3.3 Millivolt (mV) Calibration (6+ only) Oxidization Reduction Potential (ORP or Redox) as measured by an ORP electrode in mV units is not a precise measurement, but is useful as a relative indicator. As such, mV offset adjustment is not meant to enhance accuracy, but rather to make readings comparable to a reference.

  • Page 16: Temperature Calibration

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3.4 Temperature Calibration With Temperature Probe (Automatic Temperature Compensation) The thermistor sensor used for temperature measurement is accurate and stable, so frequent calibration isn’t required. Temperature calibration is recommended upon electrode replacement, whenever the temperature reading is suspect, or if matching against a certified thermometer is desired.

  • Page 17: Without Temperature Probe (Manual Temperature Compensation)

    Instruction Manual pH 5+, pH 6+, Ion 6+ Without Temperature Probe (Manual Temperature Compensation) If a temperature probe is not connected, the meter compensates for pH response based on the factory default value at 25.0 °C. This default temperature can be manually adjusted using the procedure below.
