Site preparation required
This instrument needs site work before delivery — typically a level grouted foundation, a dedicated power supply, and in some cases drainage or extraction. We issue the foundation drawing and utility schedule with the quotation so the civil work runs in parallel with the lead time.Support available
- Installation & commissioning
- Calibration
Calibration is arranged through NABL-accredited laboratories under the relevant scope. We state the scope and the certificate number on the quotation — see what accreditation actually covers.
