A hay moisture meter measures moisture in hay and other supported fibrous materials for routine sampling, bale checks and incoming-material inspections. Choose a hay moisture tester suited to the material you handle, whether baled hay, straw, forage or bran.
The models on this page differ in material coverage, probe length and measuring range. For a bale moisture meter, compare the TK100H’s 280 mm needle, the KMS680H and MS-H’s 370 mm probes, and the MS300H’s 500 mm probe. The TK100 and TK100W use electrical resistance measurement and support additional materials. Display features, compensation and power-off controls also vary by model.
How to Choose
Supported materials: Match the listed materials to your samples. The MS-H and MS300H list specific forage materials, while the TK100 includes wood fiber and grain and the TK100W includes sawdust, bamboo powder and peat.
Probe reach: Compare the TK100H’s 280 mm needle, the KMS680H and MS-H’s 370 mm probes, and the MS300H’s split 500 mm probe for sampling inside bales or loose material.
Measuring range: The KMS680H lists 4-80%; the TK100, TK100H and MS-H list 0-80%; the MS300H and TK100W list 0-84%. Check the product specifications for accuracy details and applicable conditions.
Method and compensation: The TK100 and TK100W explicitly use electrical resistance. The MS-H and TK100W include automatic temperature compensation; the MS300H includes temperature and humidity compensation.
Reading and power controls: The KMS680H includes a moisture alarm and data hold. The TK100H offers manual and automatic power-off, while the TK100W lists manual power-off and five-minute auto power-off. Check individual specifications for complete controls.
Questions Before Ordering
Which hay moisture meters can sample inside a bale?
The KMS680H, TK100H, MS-H and MS300H describe probes for deeper sampling in bales or fibrous material. Their listed probe lengths range from 280 mm to 500 mm; check the product specifications or manual for sampling instructions.
Can these hay moisture testers also check straw or grain?
The KMS680H, TK100, TK100H and MS-H explicitly list straw among their supported materials. The TK100 also lists grain; check each product’s specifications or manual before using it on another material.
Which model has a moisture alarm?
The KMS680H lists a moisture alarm that helps users notice readings above their chosen threshold. Check its specifications or manual for alarm setup and operation.
What moisture reading is suitable for storing my hay?
The supplied product descriptions do not specify suitable storage thresholds. Check the product specifications or manual for guidance on interpreting readings for your material.
