2. Quotation — We send a scoped proposal, usually within 1 business day.
3. Confirmation — You approve the quote and confirm the service mode (in-house or on-site).
4. Scheduling — We align on a equipment drop-off or pick up date or site visit timing.
5. Calibration & Report — Instruments are calibrated and a certified report is issued.
6. Invoice & Payment — Invoice is issued upon job completion.

Is there a minimum order quantity?
No. We calibrate single instruments as readily as bulk orders. For larger accounts or recurring annual contracts, we offer tailored service agreements — ask us about our contract pricing.

What is on-site calibration and when should I choose it?
On-site calibration is the right choice when your instruments are large, fixed in place, or operationally sensitive — such as environmental monitoring systems, cold room sensors, or weighing platforms in a production line. Our technicians travel to your facility with portable reference standards and calibrate instruments in situ, minimizing downtime.

How do I schedule an on-site calibration visit?
Contact us with your site address, instrument list, and preferred timing. We work around your operational schedule — including shift hours — to minimize disruption. Most visits are confirmed within 3 business days of your enquiry.

What happens during an on-site calibration visit?
Our trained technician arrives with all necessary reference equipment, performs calibration at each instrument location, and records “as found” and “as left” measurements, where applicable. A brief debrief is available upon request before we leave your site.

When will I receive my report after an on-site visit?
On-site calibration reports are issued within 1 week of the completed site visit. Reports are delivered digitally and meet all SAC-SINGLAS documentation requirements.

Can I request photographic documentation of the calibration process?
Yes. Photographic records of the calibration process is possible upon request for both in-house and on-site jobs — useful for audit trails and internal QMS records.

What is in-house calibration and how does it work?
In-house calibration means you send or deliver your instruments to our accredited lab at 28F Penjuru Close #01-05, Singapore 609134. Our technicians calibrate them under controlled conditions against traceable reference standards, then return them to you with a calibration report.

How long does in-house calibration take?
Our standard turnaround is approximately 4 working days from equipment drop-off to collection. Or equipment pick up by our team and return within the next 4-5 working days.

Express or Same day service is available at additional cost, reach out today to see if possible.

Do I need to prepare my instruments before sending them in?
Yes — instruments must be clean and in proper working condition. UniCal does not carry out equipment repairs. Sending faulty instruments may result in delays and additional downtime.

If an instrument is found to be faulty, damaged, or otherwise unsuitable for calibration after work has commenced, a charge of 50% of the quoted calibration fee may apply to cover the inspection, setup, and calibration work already performed. In this situation, no calibration report will be issued. If calibration report

If you are unsure about the condition of your equipment, please contact us first and our team will be happy to advise.

When will I receive my calibration report for in-house jobs?
Your calibration report will typically be ready at the point of collection or delivery of your instruments.

For express calibration services, the calibrated instruments may be ready earlier; however, the calibration reports will generally be issued on the next working day, as all reports must undergo a final review and approval by an authorised signatory before release.

Electronic calibration reports (PDF certificates) will be sent via email or WhatsApp upon receipt of payment or payment advice confirmation.

What Unical calibration report includes?
Each report documents the customer(user) details, instrument identification details, calibration date, reference standards used, “as found” and “as left” measurement results (where applicable), and the authorised signature of our accredited technician and calibration officer. Reports fully comply with ISO/IEC 17025 and SAC-SINGLAS requirements, unless otherwise stated.

How accurate will my instruments be after calibration?
Accuracy after calibration may vary between different equipment models. Calibration by UniCal provides clear, precise data that gives you confidence in your measurements and enables informed operational decisions. The report tells you exactly how your instrument is performing, giving you data to make informed decisions about continued use, adjustment, or replacement.

How often should I recalibrate my instruments?
The industry standard is usually annual calibration, though your internal SOPs, industry regulations, or risk profile may require more or less frequent intervals. Critical instruments in pharmaceutical cold chains or food production lines often warrant calibration every 6 months. Unical can recommend on a suitable schedule for your specific setup.

How is calibration priced?
Pricing is based on instrument type, quantity, and service mode (in-house vs. on-site). On-site jobs include a transport/mobilization component. We provide itemized quotations so you know exactly what you’re paying for before committing. Request a quote here.

When is payment due?
Payment is invoiced upon completion of calibration services. For first-time clients, payment is due after service rendered and before release of calibration report. Established contract clients may be eligible for extended payment terms — speak to us when setting up your service agreement.

What payment methods does Unical accept?
We accept bank transfer (PayNow / local bank transfer). Payment details are included on every invoice.

Can calibration actually save my business money?
Yes. Inaccurate instruments lead to product spoilage, failed audits, regulatory penalties, and customer complaints — all of which cost far more than a calibration service. Regular calibration also demonstrates due diligence to auditors, protecting your certifications and business reputation.
