ZX series of 6 decade boxes are designed for resistance thermometer simulation for accurate and reliable applications in laboratories and on site.
They are built with resistance stabilised through a controlled ageing process, mounted on low contact resistance switches.
On request, they can be supplied with a COFRAC calibration certificate delivered by our accredited laboratory. |
