Fit pH calibration parameters and generate new configuration file This function estimates pH calibration parameters using Sea-Bird's calibration equation.

Description

Fit pH calibration parameters and generate new configuration file

This function estimates pH calibration parameters using Sea-Bird's calibration equation.

Usage

ph_calibration(
  ph,
  temperature,
  ph_voltage,
  xmlcon_in,
  xmlcon_out = NULL,
  ph_serial_number
)

Arguments

ph	ph of the reference standard
temperature	Reference standard temperature in degrees celcisus
ph_voltage	Measured pH channel voltage at the reference standard
xmlcon_in	Filepath to the current CTD configuration file.
xmlcon_out	Filepath to the output CTD configuration file.
ph_serial_number	Serial number for the pH sensor (typically four digits.)

# Example of pH calibration with a demo file

ph_calibration(xmlcon_in = system.file("./extdata/example/SBE19plusV2_8106_ph_DO_leg2.xmlcon", package = "gapctd"),
               ph_serial_number = 9090,
               ph_voltage = c(1.977, 2.797, 3.534),
               ph = c(4, 7, 10),
               temperature = 23)
