Moisture meter calibration

[solo]

Just wondered how everyone has /is planning to calibrate their moisture meters? I presume calibrated samples are the way to go this year. My sinar froze at last years moisture clinic so had to go back for a health check. The readings shouldn’t be far out having been accurate since. There is nothing worse at harvest using inaccurate figures for drying grain.

The thing with them meter clinics is....My meter is right and the samples are wrong .
But seriously, I used to go to 3 crop do`s and the samples at each one did not agree with each other. If you think about it, after dozens of farmers have tipped the sample =s into their meters during the day, the samples must change.
Who tests the meters that originally tested the samples,Who tests them and then who tests them, never ending puzzle.

Usually get check samples....but despite being calibrated....it differs wildly to what the merchants meters read. I wonder why I bother really.

Took mine to the local merchants this afternoon.

....and to make it worse this year all merchants are pulling out of on farm sampling too!

I’ve bought check samples for mine.

I use the varieties I am growing, and oven dry a subsample at 105°C to constant weight to assess the moisture content. I do it in triplicate, record it all for all varieties, and if I have to make a calibration adjustment I record that as well. Keeps the inspectors happy!

You won’t get any more accurate than that

My malting barley samples have been posted for a few years now and results have been fairly quick. My daughter did sampling for a couple of seasons. She may have visited a number of people on here from the three counties.
Last years samples were too moist according to the merchant, but when the grain was sold, the results from the end users matched with my meter. ? It was a bit frustrating during harvest, that the merchant tests caused me to question the accuracy of the meter, having just shelled out for a service and calibration.

I take a sample into Openfield get it tested then calibrate meter ( the lab and hq close by )
this year may have a problem getting the sample back
so I plan to draw a sample from the heap into a 2 gallon bucket fill 2 sample bags test both they should read the sam then send one to Openfield and when the result is returned use the second sample to calibrate to

imho a moisture meter should be checked at least daily
reducing over or under drying and increase no of days combining

Openfield Check each of their testers every day

Professional meters ought to be on the ring main and the testing is overnight.

Any commercial store/lab should be ring main checked at fixed intervals, ours is about twice a month in harvest and then checked every day against a known sample. Ours certainly is!

Will be taking mine to the local tractor dealership for my calibration this year

For starters, Western Arable has a scheme where you leave your meter at their office, it's tested and you pick it up after it's been tested. I think it's free, but must check.

Exactly where I have been today. Good service from those guys.

What type of meter do you have?

@Brisel Dickie john serviced annually by the importer with quality oven teted samples and then on the frontier ring check scheme!
