A milliohmmeter with 4 terminal test standard and +/- full scale values
The MTS range of milliohmmeter test standards are designed for the simple and easy calibration of low resistance ohmmeters and Kelvin/Thomson bridges. The four terminal resistance values are switch selected and provision is made + and - full scale values. A four terminal zero value may also be selected, thus making zero and full scale calibration of instruments simplicity itself.
Three models are available, the MTS1A which has 11 values from 1mΩ to 100kΩ and the MTS2 has 10 values from 400µΩ to 400kΩ, making it ideally suited for the calibration of digital instruments with a long scale length of 4,000 or 6,000 count. The MTS3 is designed for easy calibration for units such as the Cropico DO7010, where a pulsed current is produced. The test standards are housed in a rugged bench portable aluminium case with tilt handle. The internal standards are manufactured from premium quality resistance wire with low temperature and load coefficients. The units are supplied complete with a calibration certificate.
4 terminal construction, high stability resistance standard with wide range
The RS3 range of resistance standards are constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending on the value, mounted on formers which have a high mechanical stability. The wires are wound in a strain free manner and heat treated to remove any stresses. They are also artificially aged under the strictest control. The result is a standard of high quality with long term stability and permanence of calibration combined with a low temperature coefficient.
The RS3 range also offers a high current carrying capability which makes them ideal for applications where precise current needs to be measured.
High accuracy cost effective 4 terminal calibration resistor
This range of low cost 4 terminal calibration resistors combine high accuracy, class 0.02, long-term stability and permanence of calibration in a compact unit.
Constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending upon value and mounted to ensure mechanical stability, these resistors will provide a cost effective addition to any laboratory or workshop. Typical applications include calibration reference, accurate current measurement, instrument calibration and accurate shunt resistors.
