TheGreenSpec - Greenspec pH Sensor

The pH sensor is a conventional sensor, we just added a good electronic unit. This will then convert the signal to a 4-20 mA signal. We offer two types of mounting holders: to glue or to screw on. Normally you only have to calibrate every 6 months, the lifetime of the sensor is 1 year. (Together with the CO2 sensor this is one of only two sensors that have to be replaced frequently). After that you replace only the sensor part. You put it in the holder and then you can easily fix it to the electronics with the special connector. Recalibrate after replacing!
