Cases & Covers
Protection for your instrumentation, even under the most demanding field conditions.
Insulating covers
Our insulating cover for our surface vault sensors (Trillium 120Q/QA, Trillium 360) provides thermal insulation and protection from external air currents. The easy-to-install cover includes a foam base gasket and a rigid form-fitting cover. Properly installed, it will attenuate temperature-induced long-period noise by up to 40dB. A sensor cable with a right-angle connector is required when using the insulating cover.
