Only one analog pressure gauge comes with the Prep/Scale holder. If you desire operation with two gauges, you may purchase an extra analog pressure gauge with catalog number: B26524. Alternatively, you may purchase the Digital Pressure Gauge Kit which contains two high accuracy pressure gauges with 3/4" sanitary clamp fittings to attach to the Prep/Scale holder.
