Leather and Paper pH Portable Meter – HI99171

The HI99171 uses the HI14143 glass body, amplified pH electrode that offers numerous features that improve pH testing for surface measurements. The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions.

  • Automatic Temperature Compensation
  • Automatic Two-Point Calibration
  • Waterproof

Features at-a-glance

 

Waterproof – The HI99171 is a waterproof meter rated IP67 for immersion in up to one meter of water for 30 minutes.

Automatic Calibration – One or two-point calibration is automatic to two selectable buffer sets.

Automatic Temperature Compensation – An integrated temperature sensor allows for automatic temperature compensation of pH measurements.

Sensor Check – Using the pH‐mV range the user can check the sensor status by reading the mV reading in fresh buffers. At room temperature (25 oC/77oF) the reading should be +/- 30 mV in pH 7.01 and greater than 150 mV difference between pH 7.01 and 4.01.

Multi-Level LCD Display – The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and probe condition.

Probe Condition Indicator – The probe condition indicator is based on the offset and slope characteristic of the electrode. There are 5 bars ranging from all 5 indicating the probe is in excellent condition and 1 bar indicating the probe should be cleaned or replaced.

Battery Error Prevention System – The meter will automatically shut off if there isn’t enough power to obtain an accurate measurement.

Battery Life Indicator – The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.
