HI8417, HI8519, HI8520 and HI8521 Hanna Instruments bench-
top pH meters are designed for simplicity of use.
They feature: large liquid crystal display (LCD), user friendly key-
board, 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.
