ELECTRICAL DATA
Channel A:
of low impedance, galvanically isolated, matching the output of
the SensoLyt
®
700-... armature, the adaptor ADA/pH 171
(preamplifier without temperature compensation and without
electrode check) and the connection box KI/pH 171 (preamplifier
with connection designed for temperature compensation and
temperature measurement).
Channel B:
of low impedance, galvanically isolated, matching the output of
the SensoLyt
®
700-... armature, the adaptor ADA/pH 171
(preamplifier without temperature compensation and without
electrode check) and the connection box KI/pH 171 (preamplifier
with connection designed for temperature compensation and
temperature measurement).
