Introduction
The D130 can work continuously on-line when connected to a computer or independently in the field storing data time and date into its internal memory There are 8 electrochemistry channels each of which can be assigned to pH, mV, Ion or Dissolved Oxygen. There are an additional 8 channels for temperature.
Each channel can be calibrated with either a single point or two point calibration.
pH
Selectable resolution from 0.001 pH to 0.1 pH.
Automatic calibration with any of nine pre-programmed and two user specified pH buffers.
mV
Features mV calibration for accurate ORP measurements.
Selectable resolution from 0.1 mV to 1 mV.
Ion
Direct concentration measurement, showing concentration in any unit.
The Ion mode is easily calibrated with any two standards and a blank correction.
Dissolved oxygen
Selectable resolution from 0.01 ppm/ 0.1% to 0.1 ppm/ 1%. Rapid air calibration, no zero calibration required. Manual salinity compensation 0-40 ppt. Automatic or manual air pressure compensation 800-1100 hPa.
Temperature
Manual or automatic temperature compensation.
Calibration function for temperature probes.
Special features
Three year warranty.
No electrical interference between electrodes in the same solution.
Password protection prevents any unauthorised access to the instrument.
Dust and splash-proof cabinet also suitable for wall mounting.
Logging
All channels are active at the same time, each in its own window. Each measurement is made at a time interval determined by the user between 4s and 24h. The logging can be programmed to start and stop at specific times and dates
The unit has built in clock for stand alone mode (no computer)
Memory
Stores up to 32000 values including temperature, time and date in the internal memory when working independently. An unlimited number of values can be stored when operated through a computer.
Tabulation of Data
Data is stored in a file in .CSV format which can be easily transfered into a spreadsheet. The data is presented in atable with an unlimited number of lines. This can be edited to add comments.
Graphing and Plotting
Graphs can generated using automatic or user defined settings showing alarm events, and statistical information - minima, maxima and averages.
