Meters that are regularly calibrated by us should give reliable results. Getting an unexpected claim does not always mean that your meter is wrong but is an indication that something may be wrong. A good way of ensuring that your meter is correct is to purchase known calibration standards from us (part No 1900-6352), and check your meter against them regularly throughout the harvest. At the first sign that your meter is incorrect contact the Sinar Technology Service Centre and we will help you solve the problem.
Checking your meter against another meter of different manufacture and unknown accuracy is not recommended as this can give misleading & confusing results.
There are so many interesting aspects to what we do that we though our customers might like to hear about some of them. Check out our newsletter to read about what the team have been getting up to.
