Our rental inventory is calibrated and maintained to make sure everything is functioning perfectly before we send it to you. In addition, every rental ships with a spares kit and operating manual, ensuring maximum 'up time' while the system is in use on the job site.

Benefits of renting include:

• Rental gives you access to the widest range and most up-to-date technology, allowing you to try equipment in a real world application before committing to a purchase. And, with our "try it before you buy it" program, a percentage of your rental cost can be used towards the purchase of new equipment.

• Renting is in line with the trend toward outsourcing, allowing your companies resources to be focused on your core competencies.

• Rental allows you to meet unexpected changes in job requirements.

• Rental facilitates your inspection when purchase price of the product is inhibitive, or when company budgets are not setup to allow capital equipment purchases.

• Rental avoids the need for maintenance or calibration costs. We look after the equipment, ensuring that your system will work when it is delivered on-site.

• Rental allows you to complement your existing product/service line without the large investment required to acquire the equipment.
