Precision References & Standards


The 3000ZR is an integrated 1.018V and 10V reference standard using multiple independent zeners. 

Backup power is provided via an internal rechargeable battery for transportation for calibration and use in your laboratory. The 3000ZR is fitted with power, ready and low battery indicators for visual feedback.

The 3000ZR is designed using multi-cell solid-state zener reference technology, with integrated temperature control for each individual cell. This provides robust design with the ability to sustain accidental short circuits without damage or affecting accuracy, whilst retaining a lightweight and transportable form factor.
