PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it to make sure that no damage has occurred during shipping. If there is any damage, notify your dealer.

Note: Save all packing material until you are sure that the instrument functions correctly. All defective items must be returned in the original packing with the supplied accessories.

GENERAL DESCRIPTION

HI8417, HI8519, HI8520 and HI8521 Hanna Instruments benchtop pH meters are designed for simplicity of use.

They feature: large liquid crystal display (LCD), user friendly keyboard, error codes to guide the user in calibration and troubleshooting and storage of calibration data even after the unit is shut off.

HI8417, HI8519 and HI8521 can also measure ion concentration (ISE) and ORP in the mV range (with automatic range switching from ISE to ORP when reading exceeds ±399.9mV, HI8417 and HI8521 only).

All models, except for HI8519, are microprocessor-based and provide automatic or manual temperature compensation for both calibration and measurement.

These models meet the most stringent demands of the laboratory:

HI8417 pH/mV/°C meter automatically recognizes six standard calibration buffer values-three each for NBS (pH 4.01, 6.86, 9.18) technical standard calibration buffers (pH 4.01, 7.01, 10.01).

A recorder output of 0 to 2 Volts is available and the wide mV range and high resolution allow for ORP or ion-selective measurement. HI8417 comes supplied with HI1131B glass-body combination pH electrode, HI7669/2W temperature probe (with 1 meter / 3.3' cable), 12VDC adapter (HI710005 or HI710006) and a dust cover.

HI 8519 pH/mV meter includes: manual temperature compensation and front panel knobs for offset and slope calibration.

HI8519 comes supplied with HI1332B plastic-body combination pH electrode, 12VDC adapter (HI710005 or HI710006) and a dust cover.

3

HI8520 pH/°C meter automatically recognizes 3 standard calibration buffer values (4.01, 7.01 and 10.01 pH).

HI8520 comes supplied with HI1332B plastic-body combination pH electrode, HI7669/2W temperature probe (with 1 meter/ 3.3' cable), 12VDC adapter (HI710005 or HI710006) and a dust cover.

HI8521 pH/mV/°C meter automatically recognizes 3 standard calibration buffer values (4.01, 7.01 and 10.01 pH).

HI8521 comes supplied with HI1332B plastic-body combination pH electrode, HI7669/2W temperature probe (with 1 meter/ 3.3' cable), 12VDC adapter (HI710005 or HI710006) and a dust cover.

pH/mV To select mV for mV, ORP or ISE measurements or pH for pH measurements.

Large LCD on the left

This LCD displays the temperature measured by the HI7669/2W probe or the value set manually with the keyboard. If the temperature has been set manually, the "°C" symbol will flash. When the temperature probe is connected the "°C" symbol stops flashing. When the temperature measured by the probe is out of range (-10 / +125°C), the "Err3" signal appears.

Large LCD on the right

This LCD displays the pH or mV reading. The corresponding pH or mV symbol will be displayed along with the measured value. An error signal ("Err1", "Err2", "Err4" or "Err5") will appear on this display to indicate when the range is exceeded or if the buffer during calibration is wrong.

Electrode and probe connections

For combination pH or ORP electrodes (with internal reference) plug the electrode's BNC to the socket provided (#1).

For an electrode with a separate reference, connect the measuring electrode's BNC to the BNC socket (#1) and the reference electrode's jack to the socket provided (#2).

For temperature measurements and automatic temperature compensation connect the temperature probe to the °C socket (#5).

Recorder Output

HI8417 is provided with a recorder output from 0 to 2 volts. Connect the recorder output (#4) and select the pH or mV range by pressing the pH/mV key. The output signal is related to the values as follows:

pH output:

0.01 pH = 1.42857 mV e.g. 0.00 pH = 0 mV

7.00 pH = 1000 mV

14.00 pH = 2000 mV

mV output:

0.1 mV = 0.05 mV e.g. -1999 mV = 0 mV 0.0 mV = 1000 mV

+1999 mV = 2000 mV

The output impedance is 100 ohms. The maximum output shortcircuit current is 20 mA.

RESET button

The RESET button (#3) is used when the instrument displays erroneous messages due to strong electrical interference or when the

6

instrument's power supply is disconnected before the meter is switched off. Press the RESET button and restart the entire operation.

Power connection

Plug the 12VDC adapter (HI710005 or HI710006) into the DC socket (#6).

Note: Make sure the main line is protected by a fuse.

Note: HI8417 uses a rechargeable battery to retain the pH calibration data. It lasts approximately one month when fully charged. The battery is automatically charged any time the meter is plugged-in (either turned on or off).
