I.
GENERAL
INE-
PHSJ-5 laboratory pH meter (hereafter refers to meter) is a precise pH measuring meter and
adopts high precise A/D switch chip with precise pH electrode, precise reference electrode and
precise Pt1000 temperature sensor to ensure the meter has class 0.001 pH meter‟s measuring
precision.
The meter has the following features:
To measure potential
、
pH and temperature value;
Novel touching LCD screen;
For guarantee measurement precision, the meter match with SCM technology, A/D switch chip,
accurate pH combined electrode and temperature sensor;
To select one or more PH buffer solutions to calibrate the meter(provide ten buffer solutions),
user can set calibration buffer solution groups by themselves; one point
、
two point and
multi-point calibration (max/mum five point calibration) function;
RS-232 and USB interface which can be connected with TP-16 printer to print out measuring
results or be connected with computer to communicate with outside;
Protection from electricity cutting off. The stored data and parameters will be kept even if
unusual electricity cutting off happens;
Measuring results can be stored, deleted, viewed
、
communicated and printed. It can store up to
200 different data.
