Advanced Features
Automatic Calibration
(AutoCal)
AutoCal logic controls 3 relays, user programmable with time based schedule or user initiated
(requires AutoCal panel)
Remote Validation
(Test Gas Insert)
Test gas insert allows for remote or local validation with Test Gas
(requires AutoCal panel)
Auto-Sample Rate
Minimizes drift between calibrations, increases sensor lifetime without decreasing performance when needed
Temperature Compensation
Automatic Temperature compensation to account for sensor output & used for DO calculation
Pressure Compensation
Pressure compensates/corrects for concentration calculations due to ambient or process pressure changes
Analog Input Calibration
Allows for correction/matching of Analog Input, either remote temperature or pressure transmitter
Data & Error Logging Options
Last 10 error messages and calibrations time/date stamped (.pdf file), USB data trend storage (.csv file)
OXYvisor PC Software
Configuration, programming, set-up, measurement, diagnostics, and trending (requires RS485 to USB cable)
