PH Verification Instrument
Introduction:
pH/mv verification instrument is a measurement product, is widely
used in all kinds of pH meter, iron activity meter, high resistance
millivoltmeter etc measurement and testing. It is portable type,
AC&DC double powered, could be used in laboratory and outside.
Characters:
1. Micro computer control, Key touch board; large LED three datas
display. Could display Output figure, output series number and temperature figure.
2. Use low drift, high accurate electric control system, imported
large power integrated circuit
3. Large capacity re-chargeable battery and AC adaptor, could re-charge battery while working.
4. Have high impedance and low impedance output interface, easy
using, could accurate measure, highest accuracy reach 0.0006 grade.
