EQUIPMENT, Electrical Model #DB62 - S/N 21201900062A

Dekabox DB62 Decade Resistor

Contact NAPT staff to purchase this Decade Resistor $750.00

These Decade Resistors are primarily intended for precision measurement applications where their excellent accuracy of ±0.01%, stability, and low zero resistance are important. The esi DB62 Dekabox In-Line Decade Resistor provides dependable long-term service in precision DC through audio frequency applications. Six decades of non-inductive, precision, wire-wound fixed resistors are mounted in a low noise shielded aluminum housing.

The esi DB62 decade resistor is easy to use. The input terminals and a case connected ground terminal are conveniently located on the front panel. The dials rotate independently through 360 degrees to simplify and speed settings. This allows for a coarse approximation and then precise finer steps to provide an exact resistance value.

Mensor 15000 Digital Pressure Gauge

Contact NAPT staff to purchase this Digital Pressure Gauge $100.00

The accuracy of digital measurement technology and the simplicity of an analogue gauge are combined together to create the digital pressure gauge CPG1500, which in terms of performance, ease-of-use, and instrument features, is unmatched in the pressure measurement market. The measuring rate can be user-defined to match the type of measurement required. The CPG1500 offers an accuracy of 0.1 % FS (optional 0.05 % FS or 0.025 % FS) and is temperature-compensated in the range of -10 … +50 °C (14 ... 122 °F). Readings can be displayed in one of 26 pressure and 5 level units or also in customer-specific units, so that intricate conversions are avoided. Through the new and innovative menu navigation, simple operation is ensured. The clear display, with integral bar graph display and large text area, assists with the effective analysis of the widest variety of measuring points. With the MIN/MAX function, the highest and lowest pressures can be accessed immediately and saved automatically.
