Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 3
Probe replacement and maintenance
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 4
Temperature compensation
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 5
Ingress protection and field durability
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 6
Local service and replacement parts
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 7
Verified supplier availability
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
