smartchem-ion3 1.0.0

Python interface to the SMARTChem-Ion3 ion-selective electrode instrument.

This is a python interface to the SMARTChem Ion3 ion-selective electrode instrument.

It requires the device to be connected to the host computer using a RS232 style serial port, such as through a USB-to-serial converter, and then provides a basic wrapper around the device’s control capabilities. See the device’s user manual for details on its capabilities.

Basic Usage

import smartchem_ion3

# Make a function to pretty print data obtained from the device
def handle_data(d):
    """Handle receipt of spontaneous data sent from the instrument."""
    print(f"Reading #{d.n} at {d.timestamp.isoformat()}")
    print(f"  Channel 1, {d.ch1.unit.description} = {d.ch1.value}{d.ch1.unit.suffix}")
    print(f"  Channel 2, {d.ch2.unit.description} = {d.ch2.value}{d.ch2.unit.suffix}")
    print(f"  Channel 3, {d.ch3.unit.description} = {d.ch3.value}{d.ch3.unit.suffix}")
    print(f"  Temperature, {d.cht.unit.description} = {d.cht.value}{d.cht.unit.suffix}")

# With no parameters, will use the first detected serial port at 38400 baud.
ion3 = smartchem_ion3.Ion3()

# Get a reading of the current state of the data channels and print it out
handle_data(ion3.current_data())

# Get the logged data and print them out
for d in ion3.logged_data():
  handle_data(d)
