Product Models

When safety and compliance are critical, Arlyn Scales delivers. Our ArlynGuard series of Explosion Proof Scales are engineered for Class I, II, and III Division 1 & 2, Zone 0 hazardous locations, with approvals covering Groups A through G. Backed by decades of in-house engineering and FM certification, these intrinsically safe scales provide unmatched precision, durability, and reliability in the harshest industrial environments.

Whether you’re monitoring chlorine levels in a water treatment facility, batching volatile chemicals in a refinery, or handling combustible dust in agriculture processing, Arlyn Scales has a solution built for your safety and performance requirements.

Why Hazardous Area Scales Matter

Hazardous environments pose unique challenges where ordinary industrial equipment simply won’t do. Flammable gases, explosive vapors, combustible dust, and reactive chemicals can turn routine weighing into a serious risk if the wrong equipment is in place.

Explosion proof scales provide more than just mere compliance, they are about protecting operators, preventing accidents, and ensuring accurate, traceable results in high-risk settings. With ArlynGuard Scales, you gain:

  • Confidence in compliance – every model meets FM Approval standards and is certified for use in hazardous zones.
  • Operational safety – intrinsically safe electronics and rugged construction reduce risk during daily operations.
  • Long-term reliability – stainless steel load cells and corrosion-resistant options extend service life in extreme environments.
  • Productivity without compromise – accurate, efficient weighing that keeps your workflows moving safely.

Why Choose Arlyn Explosion Proof Scales

Not all hazardous-area scales are created equal. At Arlyn Scales, we design and manufacture every ArlynGuard model in-house, giving us control over both safety and performance. The result: scales that go beyond compliance to deliver real operational advantages.

Key Differentiators You Won’t Find Elsewhere

Surface Acoustic Wave (SAW) Technology

Delivers 10× greater accuracy than traditional strain gauge load cells, available in the ArlynGuard S series. Perfect for industries that demand precision without sacrificing safety.

ArlynGuard S models are also fully approved for Zone 0 ethanol distilleries, where flammable vapor concentrations require intrinsically safe ultra-precision performance. They are also approved for many additional Classes and Divisions.

Four-Load-Cell Design for Chlorine Safety

Our ArlynGuard T is the only intrinsically safe chlorine ton scale built with four heat-treated stainless steel load cells, eliminating pivots and levers that wear out on conventional models. This design provides superior accuracy and long-term stability for critical chlorine monitoring in water treatment and chemical facilities. Because the ArlynGuard T is engineered and manufactured in-house, it also supports factory-direct customization options for platform sizing, mounting frames, and integration requirements—making it one of the top customizable intrinsically safe chlorine ton frame solutions available.

No Moving Parts = Less Downtime

Models like the ArlynGuard B, C, and F use a rugged “no moving parts” load cell design, reducing maintenance costs and extending lifespan in abusive environments.

Industrial-Grade Abuse Resistance

Scales such as the ArlynGuard F are built for forklift impacts, pallet drops, and shock loads, with 250% overload protection engineered into every platform.

Corrosion Resistance Where It Counts

Full stainless steel platforms and epoxy coatings safeguard your scale from chemicals, moisture, and corrosive agents—ensuring years of reliable service.

Smart Integration Options

From MODBUS, Ethernet, and Wi-Fi to Google Sheets and AxChange Cloud Monitoring, ArlynGuard Scales integrate seamlessly with SCADA, MES, and PLC systems—so you get safety and connectivity in one package. All advanced connectivity options (anything beyond RS-422/485) require a Safe Area display configuration such as UpScale Config 3.2 or 4.2.

Certifications & Compliance

Every ArlynGuard scale is built to meet the most stringent safety standards:

  • FM Approved for hazardous locations
  • Class I, II, III Division 1 & Division 2
  • Zone 0 certification for continuous hazardous exposure
  • Groups A–G coverage, including hydrogen, acetylene, solvents, dusts, and fibers

With these approvals, ArlynGuard platforms are fully certified to operate safely in explosive gas environments such as Class I Group B hydrogen applications, ensuring both compliance and operator protection in the most demanding industrial conditions.

  • Distilleries & Laboratories – Bench scales for precise weighing in flammable vapor environments.
  • Fuel & Energy Facilities – Platform and floor scales for hazardous material handling and inventory control.
  • Agriculture & Food Processing – Bulk weighing in dust-filled or combustible fiber environments.
  • Corrosive Environments – Stainless steel and epoxy-coated options for industries handling ammonia, sulfur dioxide, brine, and other aggressive materials.

Integration & Connectivity

ArlynGuard Scales are engineered for hazardous locations while providing flexible integration options.

Advanced digital connectivity – including industrial protocols, networking, and cloud platforms – is supported only through Safe Area display configurations such as UpScale Config 3.2 or 4.2.

Intrinsically safe outputs remain available directly in hazardous zones.

Whether you need a simple safe-area display or full IIoT integration, ArlynGuard makes hazardous weighing smarter and more connected.

Customization Options

No two hazardous environments are the same — and neither are their weighing needs. ArlynGuard Scales are built in-house, which means we can tailor solutions to your exact application.

  • Custom Sizes & Capacities – From compact 9″ cylinder platforms to 20,000 lb floor scales.
  • Multi-Platform Configurations – Operate multiple scales from a single display.
  • Power Options – Standard rechargeable battery packs or AC power with intrinsically safe Zener Barrier for continuous operation.
  • Material Upgrades – All-stainless steel construction and epoxy coatings for maximum corrosion resistance are available.
  • Flexible Display Choices – Standard MKE-5, advanced UpScale touchscreen, or “no display” output-only setups.

With engineering and manufacturing under one roof, Arlyn Scales can deliver a scale that matches your exact compliance, capacity, and integration needs.
