Service and Maintenance

Annual service prolongs the life of your instruments and ensures accuracy.

We recommend you send instruments in for service and maintenance every 12-18 months. This small yearly investment can have a substantial impact on the lifespan of your equipment and protects your data readings from instrument drift and fouling.

Rental Period

Our rental period starts on the day after the equipment is shipped and billing continues through the day before the equipment is received at In-Situ. Customers will not be billed for Saturday and Sunday if the equipment is received on Monday or if the equipment ships on Friday.

Pre-paid Return Shipping

U.S. customers have the added option of purchasing pre-paid return shipment labels. Just request the label when placing your order. When preparing the items for return, attach the pre-paid label and drop the package at a shipping center.
