The Winchester Engineering Model 2KT Wide Range Digital Gauge Kit with NIST Calibration will replace the need to use many gauges of different ranges to achieve and maintain high accuracy (0.05% f.s.) throughout a wide span (2,500-10,000 psi). The Model 2 is explosion proof and fully temperature compensated. It has a large, vibrant one line display. It is housed in a high impact, sturdy case with an optional rubber boot for additional protection, and it includes a NIST Certificate of Calibration.
