Ordering Information
pH Probe
CS525-L ISFET pH Probe with user-speci ed cable length. Enter
length, in feet, after the -L. Must choose a cable termina-
tion option (see below).
Cable Termination Options (choose one)
-PT Cable terminates in stripped and tinned leads for
direct connection to a datalogger’s terminals.
-PW Cable terminates in a connector for attachment to a
prewired enclosure.
-CWS Cable terminates in a connector for attachment to a
CWS900-series interface. Connection to a CWS900-
series interface allows this sensor to be used in a wire-
less sensor network.
Solutions

di erent bu er solutions are required for calibration.
25586 pH7 Bu
er Solution (500 ml container). Two or more
di erent bu er solutions are required for calibration.
25588 pH10 Bu
er Solution (500 ml container). Two or more
di erent bu er solutions are required for calibration.
