Product Data Sheet

Benefits of the Strantrol® 887

Controller Include:

• Accurate and Reliable Redox Control

• Optional Sensor Wash and Flow

Switch for Peak Performance and

Safety

• User-Programmable Feed Modes to

Meet Application Needs

The second relay can be configured to control a second

feeder at an alternative setpoint, or to perform an auto-

matic sensor wash function.

The third relay can be set as a master alarm reporting

high, low, or overfeed conditions.

The unit’s (4) 4-20mA outputs may be used for direct

data recording or transmitting data to a computer or

distributed control system.

Additionally, the Strantrol® 887 controller provides an

external interrupt to accept a signal from a timer or sam-

ple stream flow switch, and a triggered input to accept a

signal from a contacting water meter.

Description

The Strantrol

887 High Resolution Redox

control system

dramatically improves disinfection monitoring and control

in industrial process and cooling water applications.

Comprised of our industry leading sensor technology,

innovative sample flowcell, unique control algorithms,

and on-site service and support, the Strantrol® 887

controller is the benchmark for ORP monitoring and

control worldwide.

Each unit is equipped with three relays that can be

configured in any combination for control, alarm or

sensor wash.

In a typical installation, the first relay is set to On/Off or

Time-Based Proportional (TBP) control. Time-Based

Proportional control enables simple chemical feeders to

mimic the accuracy of more complex PID control.
