Description

Martindale TEK904 Enhanced Decade Resistance Box

The Martindale TEK904 Decade Resistance Box is an accurate and reliable seven decade resistance box with high quality rotary switches that provide in-line readouts.

The Martindale TEK 904 decade box has an extra terminal so that an accurate potential divider can be created. With a variable resistance range from 1 ohm to 11.1111 Mega ohms, an accuracy of 1% and simple operation this resistance calibration box is perfect for use in the laboratory, for educational purposes and in the calibration of test equipment.

The Martindale TEK904 decade box adds an extra decade at the bottom of the range making for an exceptionally wide range for such a compact instrument. The seven variable decades of this resistance box are 1Ω, 10Ω, 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ.


Key Features:

  • 7 Decade Resistance Box
  • Ranges from 1Ω to 11.1111MΩ
  • Accuracy of 1%
  • Suitable for laboratory, educational & calibration applications
