We have a selection of Precision Reference Standards to help you create the most accurate calibrations.

3000ZR PRECISION ZENER REFERENCE

The 3000ZR is an integrated 1.018V and 10V reference standard using multiple independent zeners. It features an internal rechargable battery, so you can take it on-site or use it in your laboratory. The 3000ZR is fitted with easy to see power, ready, and low battery indicators.

The robust design gives the 3000ZR the ability to sustain accidental short circuits without damage or affecting accuracy, while remaining lightweight and transportable.

3000RS PRECISION RESISTANCE STANDARD

The 3000RS offers annual stabilities of better than 5ppm without the need for an oil bath, with temperature co-efficients as low as 0.1ppm/°C

Using the 3000RS with the 8500 low thermal scanner provides an automated solution for calibration of precision multimeters.

3000HR PRECISION REFERENCE STANDARD

The 3000HR provides a traceable source for high-voltage resistance, consisting of a buildup box of 1 GOhm and 10 Gohm resistors, allowing a buildup to 100 Gohm.

With the 3000HR, with comparison to a 1 GOhm standard, values of up to 100 GOhm can be generated.

To assist with automating the calibration of sensitive electrometers, an RS232 interface is provided to switch decade values, from 1 MOhm to 100 GOhm, suitable for resistance calibration and low-current sourcing.

3000CS PRECISION CURRENT SHUNT

The 3000CS provides a precision set of current shunts for current ranges from 10mA to 10A, being a set of 4 shunts with dedicated current input and voltage sense inputs, with 1 year stability of up to 5ppm, and temperature coefficients of less than 0.6ppm/°C.

PRIMARY AC/DC SHUNTS

Transmille offers a set of current shunts which enable measurement of current from 1mA  to 100A. Each shunt develops 0.7V at nominal full scale, enabling a wide range of multimeters to be used without loss of resolution due to changing range.

2090 PROGRAMMABLE DECADE RESISTANCE BOX

The 2090 provides passive resistance output, and exactly mimics the performance of traditional decade boxes. For use without a computer, the 2090 provides control via keys on the front panel, and a display to indicate the current output.
