Shanghai – TOBO GROUP, a leader in industry-specific testing solutions, is proud to launch the Agricoat Corr Salt Spray Tester—a specialized system engineered to address the unique corrosion challenges of agricultural equipment and infrastructure, from tractors and harvesters to irrigation pipes, fertilizer storage tanks, and greenhouse metal frames. Unlike generic salt spray testers that fail to replicate the harsh, chemical-laden environments of farming, this platform combines agricultural-specific stressor simulation, chemical corrosion resistance testing, and durable equipment compatibility to ensure farm machinery and components withstand decades of exposure to fertilizers, pesticides, soil salts, and extreme weather—critical for avoiding costly downtime during planting and harvest seasons.
Agricultural equipment faces a dual threat of corrosion: chemical degradation from fertilizers (ammonium nitrate, potassium chloride) and pesticides (acidic or alkaline formulations) that break down protective coatings, and environmental exposure to soil salts (especially in coastal or arid regions), high humidity in greenhouses, and temperature swings (freezing winters to scorching summers). A tractor’s metal chassis, for example, can corrode rapidly after repeated contact with fertilizer-sprayed fields; irrigation pipes made of steel or aluminum may develop leaks due to soil salt ingress, wasting water and reducing crop yields. Traditional salt spray testers only simulate basic salt fog, ignoring the chemical interactions that accelerate corrosion in agricultural settings—leaving farmers and equipment manufacturers with incomplete data that leads to premature failures.
At the core of Agricoat Corr is its Agro-Chemical Corrosion Simulation Module, designed to replicate the chemical stressors unique to farming. Unlike standard testers that use only NaCl solutions, this module lets users mix and test with agricultural-grade chemicals: liquid fertilizers (3–10% ammonium nitrate solutions), pesticide mimics (pH 3–11 adjustable to match common formulations), and soil extract solutions (capturing mineral salts and organic acids from farm soil). The module maintains precise control over chemical concentration and exposure cycles (e.g., “2 hours fertilizer spray + 12 hours salt fog + 8 hours drying”), mimicking real-world use where equipment is repeatedly exposed to chemicals, rain, and sun. A farm equipment manufacturer testing tractor fenders used this module: “Traditional testers showed our coating held up to salt spray, but adding fertilizer solution revealed breakdown after 300 hours—exactly what happens in the field,” says their materials engineer. “We adjusted the coating to resist ammonium nitrate, and Agricoat Corr validated it would last 15+ years on farms.”
Durability and ease of use are critical for agricultural settings, where testing may happen in farm workshops or rural labs with limited technical staff. Agricoat Corr features a rugged, dust- and water-resistant exterior (IP66-rated) that withstands farm debris and harsh storage conditions, while its intuitive touchscreen interface uses plain-language prompts (“Select Crop Type: Corn/Wheat/Vegetables” to auto-adjust for common chemical exposures) and pre-loaded test profiles for popular equipment (e.g., “Tractor Chassis,” “Irrigation Pipe,” “Fertilizer Tank”). The system generates simplified “Farm-Ready Reports” with clear recommendations (e.g., “Replace sprayer boom coating every 5 years”) instead of complex technical data, making it accessible to farmers and maintenance teams without specialized training.
Agricoat Corr complies with agricultural equipment standards including ISO 12944-2 (corrosion protection for rural environments), ASTM G85 (modified salt spray for chemical exposure), and SAE J2334 (corrosion testing for agricultural machinery). It also uses eco-friendly, biodegradable test solutions that can be safely disposed of on farms, aligning with sustainable agriculture practices.
“Agriculture doesn’t stop for equipment failures—planting and harvest seasons wait for no one,” says TOBO GROUP’s Agricultural Testing Director. “Agricoat Corr is built for the realities of farming: it simulates the chemicals, soil, and weather that farm equipment actually faces, delivering actionable data that keeps operations running smoothly. It’s corrosion testing that works as hard as farmers do.”
The system includes a Farm Maintenance Kit with coating thickness gauges and corrosion inspection tools, and it offers remote monitoring via a mobile app—letting farmers and manufacturers track tests from the field or office.
