Calibration and Metrology at Solar Farm Thailand
Quality Systems · Metrology
Solar Farm Thailand is a Thai GACP certified indoor medical cannabis farm in Pathum Thani, Thailand. Every scale and balance we use is calibrated to documented procedures and backed by a calibration certificate, so the measurements our team relies on stay accurate and repeatable. Calibrated measuring equipment is part of the GACP standard: it supports the batch records and third-party Certificates of Analysis that licensed buyers depend on.
Frequently asked
Calibration, standards & documentation
How does Solar Farm Thailand calibrate its scales?
Every scale and balance in the facility is calibrated following documented standard operating procedures and verified against reference weights. Each instrument carries its own calibration certificate on file, so the weights recorded across cultivation, processing and packaging stay accurate and repeatable, batch after batch.
What does a calibration certificate show?
A calibration certificate records that an instrument was checked against a known reference and that its readings fell within tolerance. It documents what was tested, the result, and the date, creating a traceable, auditable record that the measurements behind our batch documentation can be trusted.
Which standards govern Solar Farm Thailand’s quality and measurement systems?
Solar Farm Thailand is certified to Thai GACP by the Thailand Ministry of Public Health. Under GACP, measuring equipment used in cultivation and processing must be calibrated and maintained, so calibration is part of the certified standard, not an optional extra.
How often is equipment recalibrated?
Calibration is carried out on a scheduled basis as defined in our SOPs, and instruments are re-checked whenever accuracy could be affected. Each calibration is logged, so the maintenance history of every instrument can be reviewed during an audit.
Why does calibration matter for medical-cannabis buyers?
For a licensed buyer, the number on the scale is the number in the batch dossier they release against. Accurate, documented measurement underpins dosing, yield reconciliation and the figures on a third-party Certificate of Analysis, turning “medical-grade” from a claim into a record you can audit.
How does calibration support Solar Farm Thailand’s GACP certification?
GACP requires that measurements behind a batch record can be trusted, so calibration is part of the evidence, not an extra. Solar Farm Thailand holds Thai GACP certification, and the calibration certificates and equipment records described above are what an auditor or a licensed buyer reviews alongside the third-party Certificate of Analysis for each batch.

The instrument register behind the certificates
Typical practice is a master register giving every measuring device a unique identifier and recording its location, range, required tolerance, calibration interval and next due date. Under that system the identifier is written beside each weight in the batch record, so any figure on paper traces back to a specific balance.
The register also drives the schedule: an instrument past its due date is tagged out of service until checked, and a status label carrying the last and next calibration dates tells whoever picks it up whether it may be used.
Verification before use versus periodic calibration
Calibration is the formal comparison against a reference weight at the SOP interval, documented by a certificate. Verification is the short check before weighing: a known check weight goes on the balance, the reading is compared with the SOP tolerance, and the result is logged with date and operator’s initials.
That check only means something if the balance is levelled, warmed up, on a stable bench, draught shield closed, away from ventilation outlets. The reference weights need the same care: handled with forceps, kept in their case, and backed by their own certificate tracing their value to a national standard.
What an auditor pulls, and what commonly goes wrong
A GACP auditor or a buyer’s QA team usually works backwards from a batch record: pick a recorded weight, ask which instrument produced it, then ask for the register entry, a certificate valid on that day and the verification log for that shift. The certificate should show as-found and as-left readings, and the log should have been written at the time, not afterwards.
- Calibration dates missed because nobody reviews the register.
- A balance moved to another room and used without re-verification.
- Small samples weighed on a floor scale whose readability is too coarse for the tolerance required.
An out-of-tolerance finding triggers a deviation record and an impact assessment covering every batch weighed on that balance since the last good check. Material still on site is re-weighed on a verified instrument and the root cause recorded. That trail, from finding to closure, is what a licensed buyer looks for alongside the quality-system documentation and third-party Certificate of Analysis that Solar Farm Thailand makes available on request.
