Ordering Information

The Rosemount 389 and 389VP General Purpose pH/ORP Sensors are housed in a molded
Tefzel body with 1 in. MNPT forward and rear facing threads suitable for insertion,
submersion, or flow through installation. The sensors can be configured with a general
purpose pH, high pH, or platinum ORP electrode. Rosemount 389VP sensors are offered
with SMART preamplifiers for pH measurements and standard integral preamplifiers for
ORP measurements. These sensors may be configured without a preamplifier, but must be
used with a remote preamplifier (j-box or transmitter). Automatic temperature
compensation is standard. Sensors are available with either an integral cable connection
(389) or Variopol (VP6) connector (389VP). Variopol cables sold separately (see
4
Table 5-2).
