Use the cable gland within the transmitter.
For wiring, refer to right figure .
Cables, terminals and glands
For the PH202G, PH202SJ use cable of outside diameter 6 to 12 mm. When using individual
electrodes -- glass electrode, reference electrode -- and separate temperature sensor, rather than
an all-in-one sensor, use the circular packing with four holes. Plug the unused hole in the packing
with the black plug. When using this packing, you have to be careful to ensure that it is well enough
sealed to be waterproof.
