I have an ALTRONIX device, we use in the laboratory for a time. It's a Thermal PH Meter mod TPX. I have to replace the probe sensor wich has a DIN circular connector (four wires), with a spare probe that has a DB9 connector type. So I need a connection diagram to can wire an interface cable. I don´t want to make external measures with a tester by the risk of damage the probe. Can anybody bring some help ? Thank you very much. Roberto
