MODEL 396/396VP/397/398/398VP SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
The Model 398 Sensor, housed in a titanium tube and made with a patented Tefzel ref-
erence junction, can be used with a 1 inch MNPT process connector (purchased sepa-
rately). The sensor is available with a hemi bulb glass pH electrode or a platinum and
glass ORP electrode and with Pt100 or 3K temperature compensation. The 398 is pro-
vided with a standard 15 ft cable. A preamplifier must be used if the sensor is more than
15 ft from the analyzer/transmitter. Junction box kits with preamplifiers must be ordered
separately. Process connector must also be ordered separately.

The Model 398VP insertion/submersion sensor is the same as Model 398, except
the cable is replaced with a Variopol connector. The watertight Variopol sensor-to-
cable connector uses the mating connector cable (ordered separately).
