This Python package (mettler_toledo_device) creates a class named MettlerToledoDevice, which contains an instance of serial_device2.SerialDevice and adds methods to it to interface to Mettler Toledo balances and scales that use the Mettler Toledo Standard Interface Command Set (MT-SICS).

Example Usage

from mettler_toledo_device import MettlerToledoDevice
dev = MettlerToledoDevice() # Might automatically find device if one available
# if it is not found automatically, specify port directly
dev = MettlerToledoDevice(port='/dev/ttyUSB0') # Linux specific port
dev = MettlerToledoDevice(port='/dev/tty.usbmodem262471') # Mac OS X specific port
dev = MettlerToledoDevice(port='COM3') # Windows specific port
dev.get_serial_number()
1126493049
dev.get_balance_data()
['XS204', 'Excellence', '220.0090', 'g']
dev.get_weight_stable()
[-0.0082, 'g'] #if weight is stable
None  #if weight is dynamic
dev.get_weight()
[-0.6800, 'g', 'S'] #if weight is stable
[-0.6800, 'g', 'D'] #if weight is dynamic
dev.zero_stable()
True  #zeros if weight is stable
False  #does not zero if weight is not stable
dev.zero()
'S'   #zeros if weight is stable
'D'   #zeros if weight is dynamic

devs = MettlerToledoDevices()  # Might automatically find all available devices
# if they are not found automatically, specify ports to use
devs = MettlerToledoDevices(use_ports=['/dev/ttyUSB0','/dev/ttyUSB1']) # Linux
devs = MettlerToledoDevices(use_ports=['/dev/tty.usbmodem262471','/dev/tty.usbmodem262472']) # Mac OS X
devs = MettlerToledoDevices(use_ports=['COM3','COM4']) # Windows
dev = devs[0]
