Decade Boxes and Resistance Standards
Cropico MTS Series
A test standard for milliohmmeters with 4 terminals 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.
Cropico 00 Series
005/6/8 High Accuracy Resistance Decade Boxes / 5, 6 & 8 Decades + Special Models for Pt100 Simulation.
A versatile range of resistance decade boxes available in 5, 6 & 8 decades. High Accuracy and wide range 0.001ohm to 11Megohms are combined in a compact lightweight case. The switches have gold plated contacts to ensure a low contact resistance and negligible thermal emf.
Cropico RBB Series
Combining high quality, long life and permanence of calibration, the RBB Series offers an unbeatable selection of models. The reliability is built in as we use our own designed and manufactured switches combined with high quality wire wound resistors.
Cropico RBC High Dissipation
RBC High Dissipation Resistance Decade 5 Watts per coil
The RBC Series is a robust range of high dissipation resistance decades available in 5 or 6 decade versions and suitable for applications where reasonably precise and stable adjustable loads are required.
Cropico RM6
RM6 Resistance Decade / Total Resistance 11.1111 M Ohms, Resolution 10Ohms
This small cost effective decade resistance box further enhances our comprehensive range, offering excellent value for money. This 6 decade model has a total resistance of 11.1111 Megohms with a resolution of 10ohms. The accuracy of ±1% is achieved using thick film resistors which have a power rating of 0.4 Watt.
The RM6-N is a space and cost-saving 6 decade resistance box . 3 models are available covering the range 1ohm to 111.111 Megohm. An additional 1kohm resistor is available at the terminals enabling the user to make a simple divider. The RM6-N incorporates 0.6 watt thick film resistors with a specified accuracy of ±1%.
The RM6-Ns constitute an ideal tool for use in all electrical and electronic laboratories or workshop environment offering a wide range of values with minimum cost
Cropico RH9A
RH9A High Resistance / High Voltage Decade Boxes - Total Resistance 1 Terraohm - Resolution 1 kilohm - Max Voltage 5000 Vdc.
Designed using the Cropico High Quality SP1 switch combined with specially selected resistors, this range of high ohm resistance decades is ideal for the calibration of insulation test sets with a voltage rating up to 5kV. Housed in a rugged plastic carrying case with up to 9 decades the RH series covers the range 1 kΩ to 1 TΩ and is equally at home in the laboratory, workshop or field application.
