General Information
The DKK-TOA Industrial
process control pH and ORP analyzers and transmitters are available from
Analyticon with many options and configurations available to accommodate
an entire range of applications. As a leader in analytical sensor technology,
many years of expertise and innovation have been incorporated into the
finest process control equipment in the world. 
Every process monitoring
environment will have unique requirements including sensor configuration
of the electrode, cell type and configuration, system pressure and cleaning
requirements.
In addition to the
main controller, Analyticon offers automatic sensor cleaning devices including
water jet, ultrasonic, chemical and physical sensor cleaning units.
Industrial pH Control
The HDM-136A series
pH analyzers/transmitters are designed as outdoor controllers incorporating
a 4 wire signal and AC voltage supply to the unit.
Features:
- 4 wire unit with
built in microprocessor featuring isolated output, digital indication
and rainproof construction.
- Simplified Calibration.
Data from up to 5 standards can be stored in memory for single action
calibration.
- Automatic evaluation
of electrode quality. Sensor monitors status of electrode during calibration
and displays error messages if out of specification.
- Adjustable pH range
- Standby mode as
"current pH hold" during maintenance work.
- External output
hold command function during cleaning.
- Measured value
shift function for correlation
- Manual temperature
compensation function if needed by electrode system (Non-pt temp probe).
- Auto determination
of 10kOhm and 1kOhm pt temp resistant probe.
- Automatic temperature
compensation for pH. Std conversion at 25C
- Self Diagnostics.
Automatically detects damage to glass membrane, temp probe, abnormal
data, and indicated by triggering upper/lower alarm limit (adjustable)
