Calibration Standards

RS2 Resistance Calibration Standard

 

The RS2 is a cost efficient yet highly stable secondary resistance standard in a sealed enclosure, e.g. intended for the calibration and verification of precision multimeters in laboratory, research, metrology and educational applications where a precise, yet economical resistance standard is needed.

The resistor elements used are high accuracy, low drift, hermetic oil filled/ceramic types with additional pre-aging. A PT100 temperature sensor is included for precise temperature measurement of the resistor element.

The RS2 comes with gold plated Tellurium Copper binding posts for the resistance standard element to achieve lowest EMF voltages. For detail configurations and order numbers please see the datasheet. Calibration is based on highly precise resistance standards traceable to National Standards.  A calibration report is shipped with every item.
The value of these standards lies not only in the precision components used but also in the calibration and documentation applied.

 

Besides the standard versions, custom resistances can be made available, as well as versions with other connectors.

Option Thermal Calibration:

Optionally it is possible to perform a thermal calibration of the resistance standard. The limits of 18 to 28°C are covered relative to 23°C. Although the thermal coefficient of the RS2 is extremely low (see datasheet), this may make sense if highest accuracy is required or if the thermal environment in the desired application is not stable. This option is supported by the fact that the resistance element, other than with many competitive products, can be measured with a very low uncertainty PT100 sensor.

 

Thermal Calibration:

Order Code:         RS2-TEMP

Price net/gross:   120.- € / 142.80 €

 

Option DIN/ISO Calibration:

Optionally it is furtermore possible to perform a DIN/ISO calibration of the resistance standard. This calibration is performed with a primary resistance bridge to below 0.5ppm uncertainty (depending on the resistance value of the RS2) relative to National Standards (PTB). Although the RS2 comes with a factory calibration, this option may be required if the specific application requires this. Also a DAkkS calibration is available on request.

RS1 Resistance Calibration Standard

 

The RS1 is a cost efficient yet very precise multi-resistance standard in a sealed enclosure, intended for the calibration and verification of precision multimeters in laboratory, research, metrology and educational applications where an economical resistance standard is needed. It offers TCs and annual drift rates as low as 1ppm and a resistance range of 10Ω to 10MΩ.

It is available in two versions, calibrated to different accuracy levels, both compliant to ROHS. The resistors used are high accuracy, low drift metal film, wirewound or hermetic foil types, depending on the accuracy level desired. A PT100 temperature sensor is included for precise temperature measurement of the resistor elements.

The advanced version (-A) uses wirewound and film resistors with low TCs, allowing for lower thermal and aging drift, and are e.g. intended for 6.5 / 7.5 digit DMMs. The precision (-H) version is based on hermetic, oil filled metal foil and film resistors with extremely low aging and temperature drift, for use as a secondary standard together with the most precise DMMs. The -A comes with standard binding posts, the -H with gold plated Tellurium Copper posts for lowest EMF.

Calibration is based on highly precise DMMs and precision temperature-controlled resistance standards.  Calibration data  is shipped with every item. The value of these items lies not only in the components used but also in the calibration and documentation applied.

Besides the standard versions, custom resistances can be made available, as well as versions with other terminals. Please contact us.

CS1 Capacitance Calibration Standard

 

The CS1 is a cost efficient coxial capacitance standard in a sealed enclosure, intended for the calibration of precision capacitanc / LCR meters in laboratory, research, metrology and educational applications where a precise yet economical capacitance standard is needed.
It is available in three  versions (-S, -P, -H), with a basic accuracy (deviation from nominal) of 5%, 1% or 0.1% (10pF higher), calibrated to an uncertainty of 0.2%, 0.05% or 0.02%. The capacitors used are high accuracy, low drift types. Calibration is based on high precision capacitance bridges.  Calibration data is shipped with every item, specifying C and D values for each capacitance.

Besides the standard versions, custom versions are possible.

DVR1 Voltage Reference

 

The DVR1 is a very cost efficient, yet precision voltage reference assembly, capable of generating three precise and low-drift, buffered reference voltages of 10V (single voltage version) or 10V, 1V and 0,1V (triple voltage version). It incorporates a temperature-controlled oven to stabilize the output voltages, thus limiting the impact of ambient temperature fluctuations and is e.g. intended as an OEM product to be incorporated in equipment where precise reference voltages are needed. It may also be used to build up a lab voltage reference.
The use of burried zener diodes in hermetic package in combination with other low drift components and a precision temperature control circuitry is the prerequisit of precision voltage standards. This reference uses pre-aged components and a smart design, achieving high accuracy and low drift rates at a very attractive price/performance ratio. A PT100 temperature sensor enables monitoring of the internal reference temperature.
Every product is factory calibrated, traceable to National Standards against a precision voltage standard with low uncertainty (see datasheet) after a minimum of 500 hours of pre-aging for the references and an additional 100 hours for the complete unit. The calibration includes the adjustment of the 10V output and the precision measurement of the 1V and 0.1V output (for the tripple voltage version). The single output version supports 3 buffered outputs with 10V each. The unit is accompanied by factory calibration data. Please note that the output ground and supply negative MUST NOT be connected together (not on same potential). A wire harness with 4mm (low EMF where appropriate) connectors/sockets is available too.

Custom versions can be made available, please contact us.
