Choosing and maintaining an instrument
Start with the measuring medium
An instrument for liquids is not automatically suitable for direct measurements in soil or coco. Check the probe application and the specified method. Direct substrate readings require a model designed for that purpose.
Separate or combination instrument?
A separate meter is useful when you need one parameter. A combination instrument can bring several readings together, depending on the model. Compare measuring range, resolution and stated accuracy separately. Extra decimal places do not automatically mean a more accurate reading.
Include maintenance in your choice
Check the manufacturer’s calibration solution, cleaning procedure and storage instructions. Different probes can need different care. A replaceable probe may be useful for regular use; always check compatibility.
