GRP Instrument enclosures are used for protecting instrumentation from extreme weather conditions, which can cause calibration drifts due to temperature variations. The enclosures are IP rated and shield the meters from dust, water, mechanical forces and corrosion; while allowing permeability of RF signals from wireless devices without any major attenuation. Designed to house single or multiple instrumentation with long-life viewing windows for clear visibility of the displays. GRP enclosures can be combined with a wide selection of heavy-duty mounts, high-torque hinges, latches and brackets to produce customized units that suit any application and are quick & easy to install.
