GENERAL DESCRIPTION
The
HI2550
is a microprocessor based pH, ORP, Conductivity (EC), TDS,
NaCl, and Temperature Bench Meter. Relative mV feature is also provided.
pH measurements are compensated for temperature effect manually or
automatically with the
HI7662
temperature probe.
Up to a five‑point pH calibration can be performed using seven standard
buffers and two custom buffers.
A calibration due alarm can be set to alert the user that too much time
has elapsed since the last pH calibration.
Conductivity and TDS features auto‑ranging, which automatically selects
the scale with the highest resolution. Conductivity measurements are
compensated for temperature manually or automatically with a tem‑
perature sensor located inside the probe. The temperature coefficient is
user selectable. Temperature compensation can be disabled to measure
actual conductivity.
The
GLP
feature provides data consistency.
Data can be stored in the meters memory for later retrieval. The meters
memory can hold 200 manually logged points and 500 lot logging points.
An USB connection ensures communication with a PC.
Remove the instrument from the packing material and examine it carefully
to make sure that no damage has occurred during shipping. If there is any
damage, please contact your local Hanna Instruments Office.
