Note:
Save all packing material until you are sure that the
instrument functions correctly. All defective items must be
returned in their original packaging together with the sup-
plied accessories.
HI 98230
and
HI 98240
are portable printing and logging micropro-
cessor-based pH/temperature meters. In addition,
HI 98240
provides
ORP measurements.
Both models are supplied with an exclusive HANNA (smart) amplified
pH/temperature electrode with DIN connector. The electrode has an
internal memory for storing calibration data.
All pH measurements are automatically compensated for temperature
(ATC). The instrument housing is made of rugged, lightweight material,
making it truly portable.
Five memorized buffers (pH 4.01, 6.86, 7.01, 9.18 and 10.01) and
wrong buffer recognition technology, make calibration simple and error
free. One or two point procedure can be performed.
The meters are also equipped with a stability indicator and backlight
feature for comfortable reading even in dark environments.
The GLP features provide a guarantee of data consistency.
Measurements can be performed with lab-grade precision in the field as
well as in the laboratory.
An alarm time-out is available to alert the user if too much time has
elapsed since the last pH calibration .
