Like the Model 1, the Model 2 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 need for multiple gauges is eliminated. 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. Model 2 runs on three AA batteries.
