IET / General Radio 1408 Air Bath Reference Standard Capacitor
Item Description
IET / General Radio 1408 Air Bath Reference Standard Capacitor
You are bidding on an IET / General Radio 1408 Air Bath Reference Standard Capacitor. This unit is in excellent condition, has been fully tested and is ready to ship. It has a current list price through IET of over 45K!
Description:
The continuously improving accuracy of capacitor calibrations by NIST brings a better knowledge of capacitance to standards laboratories provided, of course, the laboratories have adequate reference standards. The 1408 Reference Standard Capacitors, with their high stability, are suitable for calibration in parts in 107. The 1616 (not included) Precision Capacitance Bridge is highly recommended for accurate calibration of a wide range of working standards from such a reference.
The unit includes two standards, 10 pF and 100 pF, plus a self-contained air bath whose temperature is held constant to within 0.01 per year to assure the utmost stability of the standards. Since it carriers its own environment, it is well adapted for use in laboratories without an oil bath or closely-controlled ambient temperature or in portable laboratories and calibration centers. The air bath operates from 12 volts so that it is an easy matter to transport it under power at all times.
Features:
10 pF and 100 pF combination
High stability
Low voltage coefficient
Terminals:
Two GR-874 locking connectors or BNC connectors (connectors not included but can be supplied at an additional cost).
Specifications:
Nominal Value: 10 pF and 100 pF.
Adjustment Accuracy: ±5 ppm.
Stability: Estimated to be better than 1 ppm per year.
Temperature Coefficient: 2 ±2 ppm/°C for 100 pF; 5 ±2 ppm/°C for 10 pF.
Electrical:
Dissipation Factor: < 10-5 at 1 kHz.
Voltage: 750 V max.
Residual Impedance: See the datasheet - Figure 1 (in specifications area towards the bottom).
Terminals: Two locking G874 coaxial connectors or BNC connectors (not included)
Air-Bath Characteristics:
Temperature: 30°C nominal with stability of 0.01°C/year, < 0.005°C/hour if ambient temperature is kept within 1°C.
Temperature Coefficient: 0+0.05 ppm/°C from 17 to 29°C ambient temperature; thermometer well provided for calibration.
General: Connectors can be made to the front or the rear as your application dictates (currently setup for the front). A 12-volt input is provided to maintain a constant air-bath temperature even while the unit is in transit.
Power: 105 to 125 V or 210 to 250 V, 50 to 60 Hz, 5 W; 12 V at 0.4 A; for dc operation, battery connectors provided on rear.
Mechanical:
Dimensions: 22.2 cm H x 21.4 cm W x 40.7 cm D (8.72" x 8.42" x 16"); approx.
Weight: 12 kg (25 lb.)
