Features
•
Standard Q45P electronic transmitters are designed to be a fully isolated, battery
powered instrument. The monitor can be quickly converted to either a loop
power transmitter or line powered analyzer.
•
Two 10-bit, isolated, 0-2.5 VDC analog outputs may be configured to track pH
and temperature, or pH and pH. Both analog outputs can be individually
programmed to specific ranges.
•
Large, high contrast, custom Super-Twist display provides excellent readability
The secondary line of display utilizes 5x7 dot matrix characters for clear
message display. Two of four measured parameters may be on the display
simultaneously. An LED back light can be turned on if necessary for use in very
low light conditions.
•
Sensor diagnostics monitor glass breakage, sensor leaks, and RTD condition.
Diagnostic messages provide a clear description of any problem with no
confusing error codes to look up. Messages are also included for diagnosing
calibration problems.
•
Quick and easy two-point and sample calibration methods include auto-buffer
recognition from 3 built-in buffer tables. To provide high accuracy, all calibration
methods include stability monitors that check temperature and main parameter
stability before accepting data.
•
Selectable Pt1000 or Pt100 temperature inputs. Systems can also be hard-
configured for three-wire elements. Temperature element can be user calibrated.
•
Security lock feature to prevent unauthorized tampering with transmitter settings.
All settings can be viewed while locked, but they cannot be changed.
