HI 504920 is a complete portable pH/ORP/temperature meter, to be
used mainly with Hanna HI 504910 Digital Transmitter for two
different applications: it can be a reference pH meter for calibrating
the HI 504910 Digital Transmitter, or it can be set as user interface
for the HI 504910 as well.
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 (4.01, 6.86, 7.01, 9.18 and 10.01 pH) and
wrong buffer recognition technology make calibration simple and error
free. One or two-point calibration can be performed.
An user friendly interface provides clear messages regarding errors,
functions and more.
An alarm time-out is available to alert the user if too much time has
elapsed since the last pH calibration and that re-calibration may be
required.
The meter provides a controlled access to calibration and GLP settings
