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 Tefzel reference
junction, can be used with a 1 inch MNPT process connector (purchased separately).
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 provided
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 sep-
arately. Process connector must also be ordered separately.
