A&D Weighing HW-200KCEP Intrinsically Safe Bench Scale, 500 lb x 0.05 lb

The HW-200KCEP is an intrinsically safe platform scale designed for potentially explosive environments where flammable gases or vapors may be present. A&D lists certifications including FM/FMc Class I, Division 1, Groups C and D, as well as Class I, Zone 0 and IECEx/ATEX intrinsic-safety classifications. This makes the scale suitable for properly classified hazardous-area applications involving materials such as organic solvents and other flammable substances. Users should always confirm that the scale's exact approval markings match their facility's hazardous-location classification before installation.

The HW-200KCEP provides a maximum weighing capacity of 500 lb (220 kg) with 0.05 lb (0.02 kg) readability. A&D specifies approximately 0.04 kg repeatability and ±0.04 kg linearity, along with stabilization within approximately 1.5 seconds under suitable conditions. This combination makes it useful for larger containers, ingredients, raw materials, and production loads that need to be weighed safely in hazardous environments.

The HW-200KCEP operates from four approved D-size alkaline batteries, eliminating the need for a conventional AC power connection at the scale. A&D specifies approximately 1,500 hours of battery operation with the LED comparator and backlight turned off, or around 1,000 hours with them turned on, depending on operating conditions. Only battery types approved by A&D for the intrinsically safe configuration should be used.

Yes. The HW-200KCEP supports checkweighing, parts counting, accumulation, auto-tare, and negative comparison. Its 3-color, 5-step LED comparator lights provide an easy visual indication of whether a measured load falls within preset limits, helping operators perform repetitive filling, packing, sorting, and verification tasks. The HW-200KCEP also supports a maximum displayed count of 110,000 pieces for suitable counting applications.

The HW-200KCEP's weighing base is rated IP65 and uses a SUS430 stainless-steel weighing pan, providing protection against dust and water jets. This construction can be useful in demanding production environments where the platform may be exposed to dust, spills, or cleaning. However, IP65 does not mean the scale can be submerged, and A&D specifically describes the IP65 protection as applying to the platform/base unit.
