Conductivity or Resistivity controller. You can use this unit to measure either
Conductivity or Resistivity with fast-responding on/off control. This controller has
many user-friendly features; some of its features include:
Included with your controller
Your controller includes:
• 17-way and 5-way right angled terminal block (one each)
• side threaded rod with catch (two)
• receptacle cable lug (one)
• rubber gasket (one)
Please read through this manual carefully before installing and
operating your controller.
• A menu-driven program that
simplifies set-up
• Large dual display LCD shows con-
ductivity (resistivity) and temperature
along with clear multiple annunciators
• Two set point, two SPDT relay
operation
for lo/lo, lo/hi, hi/lo
or hi/hi control
• 0 to 2000 second time delay
adjustment
on all relays—
minimizes false alarms
• Separate alarm relay alerts you to set
points exceeded for a specific length
of time or a failed temperature sensor
• Separately adjustable high and low
set point hysteresis bands
prevent
rapid contact switching if your mea-
sured value is fluctuating near the
set point
• Adjustable temperature coefficient
from 0.00 to 10.00% per °C lets you
input your solution’s true temperature
correction for higher accuracy
• Choice of 0.01, 0.1, 1.0 or 10.0 cell
constants
for accurate readings in any
solution
• 0-20/4-20 mA transmitter/recorder
output
for remote monitoring and
hard copy recording
• Protection against electromagnetic
interference—galvanically isolated
output
• Push button keypad gives you
fast access to one-point calibration,
switchable manual or automatic
temperature compensation, and call
up to view set points
• Two level password protection—
first level allows quick access to
calibration; second level lets you
change set up parameters
• LED indicators signal control
activities to monitor controller
status from a distance
• Nonvolatile memory maintains setup
even when power fails
• power source
• the OAKTON 1000-series controller
• a conductivity (or resistivity) cell
with or without built-in temperature
sensor (Pt 100 or 1000)
• installation hardware for cell
• an appropriate measurement cable
• a final control element such as a pump
or valve
• a recorder (optional)
• a visual and/or audible alarm
(optional)
