View radiation thermometer calibration →Accredited scope and how to check it
Unitest is accredited by SAC-SINGLAS to ISO/IEC 17025 under accreditation number LA-2023-0845-C. The exact parameters, ranges and measurement uncertainties are set out in our Schedule of Accreditation, and each accredited service page shows the ranges that apply to it. See our SAC-SINGLAS accreditation and scope for the detail, or look up a specific instrument, brand or model in the instrument directory. If you are not sure whether an instrument or range is on the schedule, ask us before you send it.
On-site or in our lab, your choice
For fixed, heavy or critical equipment, our engineers calibrate at your facility to minimise downtime.
Mapping & validation of controlled spaces
Beyond calibrating single instruments, we map and qualify whole controlled environments so you can prove they hold the conditions your products and auditors require. See our temperature & humidity mapping service for warehouses, cold rooms and chambers, aligned to HSA GDP, WHO and GMP.
