The P3800 range can be used to calibrate virtually any high pressure sensing device including transducers, transmitters, gauges, pressure switches or other calibrators. P3800 series are manufactured with tungsten carbide pistons and cylinders for long term stability and durability. The models are capable of pressure ranges to 60,000 psi (4000bar), and two accuracy classes of 0.02% or 0.015% of reading.
