We describe here a cattle harness to attach a gas collection vessel to facilitate the sulfur hexafluoride (SF₆) tracer gas technique. The harness consists of 2 major components: (1) a lightweight, robust body fabricated from an equine surcingle or lunge roller with padded thoracic trapezius pressure points, a bespoke shaping shaft for spine support, and adjustable buckles on both sides; and (2) an elastic flank-strap to prevent the harness from dislodging. The spine support consists of stainless steel laminated with carbon fiber. This support minimizes the contact area with the animal's skin, relieves the spine area of pressure, and creates free flow of ambient air below the platform, reducing sweat accumulation and hence preventing skin lesions. The harness weighs approximately 1.2 kg, allows for attachment of 2 gas collection vessels (animal and background sample), and is cost effective.

我们在这里描述了一种牛具，用于连接气体收集容器以促进六氟化硫（SF ₆）示踪气体技术。该安全带由两个主要部件组成：（1）一种轻巧而坚固的车身，由马背弓或弓形滚子制成，带有加厚的胸斜方肌压力点，用于脊柱支撑的定制成形轴以及两侧可调节的带扣；（2）弹性侧带，以防止安全带脱落。脊柱支撑件由不锈钢和碳纤维层压而成。这种支撑可最大程度地减少与动物皮肤的接触面积，减轻脊柱的压力，并在平台下方产生自由流动的空气，从而减少汗液积聚，从而防止皮肤损伤。该安全带重约1.2千克，可连接2个气体收集容器（动物和背景样品），并且具有成本效益。
