ANV Hire

All the instruments ANV Measurement Systems supply are well suited to rental because of their ease of use and reliability. You won’t need to spend the first day of your rental period learning how to use the instrument. Anyway, there’s always someone knowledgeable, helpful and friendly in the ANV Measurement Systems office to help during normal office hours if you do get stuck.

It’s not just the instruments and technical support that make the ANV Measurement Systems Hire fleet different. Our accessories, like the long-term outdoor kits, are practical and site-proven. We also endeavour to keep our hire fleet stocked with new instruments and accessories. The vibration instruments are provided with traceable calibration.

Instruments are normally shipped to you on a next day courier (timed delivery) but we can also do sameday delivery to most UK mainland locations. Alternatively you are very welcome to pick up the kit from our office and to benefit from free advice & training on the use of the kit and to sample our excellent coffee.

After the first week our hire rate is daily (@ 1/7 of the weekly hire rate) and we offer a 4 day minimum hire for when you really only need the kit for a day or two.
