Description
Precision Monitoring for Hay and Straw
The Draminski Hay Moisture Meter HMM is a modern, digital solution designed to monitor both the moisture content and temperature of compressed hay and pressed straw. This cutting-edge device stands as the most robust hay and straw moisture tester in the world, engineered to meet the demanding requirements of farmers, feed suppliers, and agricultural inspectors. Built upon advanced resistance measurement technology, the HMM safeguards profits by helping you determine the precise suitability of hay and straw for long-term storage, preventing fungal contamination, spoilage, or dangerous self-heating events. Whether you produce fodder for cattle and horses, or simply require bedding with the ideal dryness, the HMM offers confidence and repeatable results. With up to 100 hours of continuous operation per charge, a corrosion-resistant stainless steel probe, and a comfortable ergonomic handle, it is the definition of agricultural reliability.
Exclusive Applications in Farming and Storage
This device excels in specialized agricultural applications that go far beyond general moisture testing. The HMM allows farmers to evaluate hay quality to prevent livestock digestive issues, precisely determine appropriate storage readiness, and ensure safe straw moisture levels to avoid accidental ignition. Bedding preparation becomes more refined as you maintain an optimal dryness for animal comfort, while feed production benefits through quality assurance before sale. For baling operations, the HMM can be used both on loose material and compact bales to verify uniform dryness across different parts of the material. Furthermore, agricultural quality controllers use it to monitor compliance with storage safety standards. Regardless of the scenario—be it a large-scale commercial hay operation, small family farm, or professional feed production facility—the HMM delivers reliable readings you can trust.
Multiple Versions for Various Agricultural Needs
Draminski understands that no two agricultural operations are exactly alike, which is why the Hay Moisture Meter HMM comes in five tailored versions. The standard model with a 56 cm probe suits most bale testing, while the 200 cm probe version reaches deep into large storage stacks. The HMM FIX features a permanently attached probe for streamlined operations. For the coffee and cocoa industries, the HMM&G version is adapted for those products. Lastly, the HMM Press version integrates into self-loading balers to provide real-time moisture monitoring during baling operations. This diversity in design ensures that your investment matches your operational workflow perfectly.
Engineering Excellence and Unmatched Durability
As the most durable hay moisture meter available on the market, the HMM owes its resilience to Polish engineering excellence. Its stainless-steel probe resists corrosion under years of agricultural use, while the dirt-resistant keypad prolongs operational life with minimal maintenance. Every meter is assembled by hand using premium European components and undergoes rigorous testing before shipment. This durability is backed by a 3-year warranty, ISO 9001 and ISO 13485 certifications, and a reputation for withstanding the harshest on-field conditions. Whether used in dusty barns, humid storage facilities, or open agricultural fields, the HMM’s construction meets professional expectations without compromise.
Easy Use with Intelligent Features
Even with its impressive technical depth, the HMM is remarkably intuitive. A clear 3.5-inch LCD display presents minimum, maximum, and average values in easy-to-read digits, so you can assess overall bale quality quickly. Automatic temperature compensation refines accuracy, while an in-device adjustment feature allows calibration to specific conditions. The HMM’s membrane keypad is rated for five million clicks, translating to years of reliable daily use. Designed for single-operator efficiency, it seamlessly integrates precision results into everyday workflow without requiring special training, making it popular among both veteran farmers and new professionals entering the agricultural sector.
Performance Verified by Professional Standards
Draminski’s production standards go far beyond basic compliance, aligning with strict international quality norms. Professional farmers appreciate the ±2% moisture accuracy in ranges up to 20% humidity and ±1°C temperature accuracy, making it a trustworthy tool for moisture-sensitive crops. Internal memory supports recognition of up to 20 different species, meaning hay and straw are just part of its broader capabilities. Even without internal data storage for results, the meter’s focus on real-time, actionable data ensures fast decision-making in moisture management—a critical factor during harvest and baling seasons.
