Seven working days, but that can change with the volume of work. Please contact Customer Service for more information.
Do you offer expedited services?
Yes, we do. Expedited calibrations are scheduled upon request and require advance notice. Equipment details must be provided to Essco by 1 PM on the day of the pickup for overnight service or blue streak service.... Overnight's are $100.00 per piece Blue streak's are $50.00 per piece, 4 day turnaround and Same Day Service is $150.00.
Do you pick up and deliver?
Yes, we do pick up and deliver in New England. You can contact Customer Service to arrange this service. They can also advise you of the cost for pick up and delivery.
How do I get my equipment to you?
If you’re in our pickup/delivery area, please contact Customer Service to make arrangements. If you’re outside our pickup/delivery area, you can ship your equipment via UPS, FedEx or any other carriers that you use.
How do I set up an onsite calibration?
Call our onsite department at 800-325-2201, x110 or x118.
Can all items be calibrated onsite?
No. Once we see your list, we can determine if the equipment needs to be done at our facility or yours.
Is there a minimum charge for onsite calibrations?
There must be at least $740 worth of calibrations to be performed per visit to send a technician onsite or a $740 minimum charge will be required.
What information do you require for an onsite calibration?
An accurate list of equipment so that we can send the right procedures, personnel and standards.
Will I be notified of repairs beforehand?
Yes, Customer Service will contact you after the unit has been evaluated.
Do you require an RMA number before calibrating our equipment?
Do you require a P.O. number before scheduling work?
For onsite calibrations, we require a P.O. number prior to the technician coming to your facility. We can pick up work without a P.O. number but require you to provide one prior to billing.
Will you remind me when my equipment is due for calibration?
Yes, we will send you a recall a month before the equipment is due.
Who determines the calibration cycles?
The customer must select a cycle for their equipment or we can assist you in determining a cycle. The cycle should be based on the instruments accuracy, sensitivity, usage, environment and the risks involved with its use. Only the customer can evaluate all these factors wisely.
Is the use of an accredited laboratory sufficient to satisfy the need for accredited calibrations?
No. You must request accredited calibrations and the measurement capability must be within the scope of accreditation for that calibration laboratory.
Do I need documented uncertainties with every accredited calibration?
Yes. ILAC, International Laboratory Accreditation Council, now requires that uncertainties must be included on the data sheet for each measurement taken.
What is the difference between an ISO17025 calibration and a commercial calibration?
Our accreditation covers specific areas of metrology that our accreditation body, NVLAP has assessed. These accredited calibrations come with an accredited certificate of calibration and measurement uncertainties not available for commercial calibrations. The accredited calibrations reflect the technical competency and higher-level quality systems required to achieve accreditation.
Are you traceable to the National Institute of Standards and Technology (NIST)?
All measurements are traceable to NIST, except where noted. NOTE: Essco does not supply NIST numbers in accordance with NCSLI Position Statement 96-1: "test report numbers should not be used nor required as proof of the adequacy or traceability of a test or measurement". NIST, NVLAP and A2LA have concurred with this position. NCSLI also notes that international standards ISO 900X, ISO Guide 25 (ISO/IEC 17025), ISO 10012 and ANSI/NCSL Z540-1 do not require the use or reporting of NIST test report numbers.
Does ESSCO have to comply with X standard?
Frequently our quality manager is asked whether we calibrate to and / or comply with standards other than ISO 9001:2015, ANSI/NCSL Z540-1-1994, ISO/IEC 17025:2017, ISO 10012:2003, ISO 13485, and TS 16949. And, when required contractually, 10CFR21 and 10CFR50 APP. B.

Some of the standards requested are:

AMS 2750D
QS 9000
CISPR 16-1-1
21 CFR Part 211
21 CFR Part 83
FAR 145

The short answer is no. Calibration laboratories and traceable calibration processes comply with three specific standards, i.e. ISO 9001 (for any business type), ISO/IEC 17025 (specific to calibration and testing laboratories) and ANSI/NCSL Z540 (specific to calibration laboratories). Other standards that calibration laboratories are asked to comply with, and even document on the certificate of calibration, are actually only relevant to specific manufacturing or testing processes of the customer, not the calibration process of the calibration laboratory. In many cases, manufacturing standards will reference the use of calibrated instrumentation from a certified or accredited calibration source. This means the calibration source complies with calibration standards such as ISO/IEC 17025, not manufacturing standards. As a manufacturer, it is your quality program that must comply with the specific standards imposed upon your processes. Other than the portion requiring calibration, manufacturing standards do not trickle down to the calibration laboratory. Essco may contractually comply with 10CFR21 and 10CFR50 App. B. etc.

Note: when a calibration laboratory is accredited to ISO/IEC 17025, it is also compliant to ISO 9001 without additional auditing, per ILAC, International Laboratory Accreditation Council.
Does data come with the certificate of calibration?
If you require data, you need to request it when you set up your account. If your account is set up with data, you will receive it with your certificate of calibration.
What if I lose the certificate of calibration?
Customer Service will be happy to email, fax or mail a copy to you. Or, you can sign up for our online service and reprint your certificates yourself. Please contact Customer Service to get set up for this service.
Do you publish a price list?
No. For pricing information, please contact Customer Service.
What are your payment terms?
Net 30 days. Invoices not paid within 60 days may be subject to a finance charge. We accept MasterCard, Visa and American Express.
What are your warranties?
Six months for electronic equipment and 30 days for mechanical equipment.
Do you rent or provide loaner equipment?
No. Please contact Customer Service for referrals to companies that provide these services.
Why do calibration suppliers have so many complex and confusing “levels” of service?
It’s marketing. Many manufacturers see calibration as a necessary evil, so they shop for price rather than quality and service. To satisfy this misguided thinking, calibration suppliers cut corners to reduce prices and attract uneducated consumers. All calibrations should be performed in accordance with the instrument manufacturer’s guidance. NVLAP, The National Voluntary Laboratory Accreditation Program and A2LA, The American Association for Laboratory Accreditation even adds additional requirements to accredited laboratories calibration procedures. You do get what you pay for, even from calibration suppliers, so you assume a degree of unnecessary risk. See “Outsourcing for Quality Calibrations” on this site.
