Details

For the measurement of pH the HI98191 comes with a HI72911B titanium body pH electrode with a built in temperature sensor for automatic temperature compensated readings. The titanium body is chemically resistant to aggressive chemicals and is virtually unbreakable.

Calibration can be performed up to five points with seven preprogrammed standard pH buffers and five custom ones to achieve a pH accuracy of ±0.002 with ±0.001 pH resolution.

Hanna's unique CAL Check™ feature alerts the user to potential problems during the pH calibration process. By comparing previous calibration data to the current calibration the meter will alert the user with display prompts when the probe needs to be cleaned or is broken and if the pH buffer might be contaminated. After calibration the overall probe condition is displayed as a percentage from 0 to 100% in increments of 10%. The probe condition is affected by both the offset and slope characteristics of the pH electrode and is displayed on the measurement screen on the day of calibration and in the GLP data.

The HI 98191 has 15 different ISE sensors (ISE-electrod not included) pre-programmed with the ion charge and molar weight. By selecting the appropriate ISE in the ISE Setup Menu, the appropriate ion charge and ion molar weight are applied to display ISE slope percentage. Users can then calibrate up to five points with the choice of seven standard values. This meter allows an extensive choice of measurement units (ppm, ppt, g/L, ppb, µg/L, mg/mL, M, mol/L, mmol/L, % w/v, user defined) and has an expanded measuring range of 1.00 x 10-7 to 9.99 x 1010.

Pressing the "AutoHold" virtual key seen in measurement mode, the meter will freeze a stable reading allowing for the reading to be documented or logged. An “out of calibration range” warning can be enabled that will alert the user when a reading is not within the bracket of calibrated pH values.

The high contrast graphic LCD is easy to read outdoors in bright sunlight as well in low-lit areas with the backlight.
