    3.4 Installation of accessorial transmitter PH-300T (Optional) Accessorial pH/ORP transmitter, PH-300T, is mainly installed on the electrode protective pipe, but it also can be applied to wall mounting or pipe mounting. For long distance transmission (100m), for example, if the distance between a transmitter and an electrode overweighs 30 meter long, it is recommended that accessorial transmitter PH-300T should be used to avoid the attenuation of electrode signal which also leads to convenience of onsite observation, measurement, and calibration.

    7. Maintenance Generally speaking, under normal operation, the transmitter needs no maintenance except regular cleaning and calibration of the electrode to ensure accurate and stable measurement and system operation. The cleaning cycle for the electrode depends on the pollution degree of the measurement sample. Normally, it is recommended to make weekly cleaning.
