Excellent value, compact and very easy to use for quick pH assessment. Being analogue it uses the negative/positive charge in the soil clay particles, so requires no corroding batteries.
Suitable for farmers (arable & grassland), lime spreading contractors, & agronomists for instant check to assess any problems with pH.
Due to huge variations in soil types, moisture levels etc. any field pH meter should be backed up by laboratory testing where more precise readings are required.
