Troemner Pipette Calibration Services

Troemner's pipette calibration program is designed to meet all of your GLP, GMP, FDA, ISO, NCCLS, CAP and CLIA requirements. Troemner repairs, calibrates and certifies any manufacturer's pipette. Each pipette calibrated by Troemner and returned to you is accompanied by a detailed, multi-page certificate that meets all necessary standards and requirements.

Troemner offers two service levels: 
Traceable Certification includes as-found data, full cleaning, disassembly, seal and o-ring replacement and visual inspection for signs of wear. Your pipette is then pressure and vacuum tested for signs of leakage. After stabilizing in Troemners Class 1000 cleanroom for 24 hours, adjustments are performed and as-left data is taken. This includes "4-4-4" testing (4 measurements at 3 different volumes). If large parts need replacement you will be contacted by Troemner and billed separately.

UltraClass Certification includes all the elements of the Traceable Certification listed above however UltraClass includes "10-10-10" testing (10 measurements at three different volumes).  In addition, the cost of all parts replaced is included in the price.

Troemner Mass & Weight Calibration Services

Currently, Troemner is an ISO 9001 registered company and is the world's leading supplier of precision weights and mass standards.   They manufacture and certify weights that meet or exceed the highest tolerance standards of the American Society for Testing & Materials (ASTM) and the International Organization of Legal Metrology (OIML).  Since 1995, Troemner’s laboratories have been accredited by the United Kingdom Accreditation Service (UKAS, formerly known as NAMAS) and the National Voluntary Accreditation Program (NVLAP) which is sponsored and administered by the National Institute of Standards and Technology (NIST).   Troemner offers either NVLAP or UKAS certification for precision weights.

Today, with working standards like GMP and GLP, quality standards like ISO, ANSI/ NCSL Z540-1 and FDA requirements, traceability to a known standard and documentation of that chain of traceability is crucial in many fields of work.  Troemner offers a full line of weight calibration services traceable to the National Institute of Standards and Technology (NIST).  When you have your weights certified by Troemner, you are guaranteeing yourself and your auditors that you have weights that were certified using a documented link to standards calibrated at NIST.

NVLAP or UKAS Accreditation

	Values from 0.5 mg to 5000 lb
	New 'UltraClass' Certification offered with uncertainty 50% better than Class 1

DH Instruments Pressure Calibration Services

For 20 years DH Instruments has manufactured the highest accuracy primary pressure standards available.  Before 1988, DHI's extensive calibration capabilities were dedicated exclusively to the calibration of DHI products. Thousands of calibrations were performed for public utilities, major aerospace companies, defense contractors, government agencies and others requiring the lowest uncertainties and conformance to formal quality assurance programs.

In the late 1980s, DHI pressure calibration service capabilities were expanded to support the calibration and testing of all types and brands of pressure instrumentation. This made DHI's unique calibration resources available to all users of pressure instrumentation seeking the best pressure metrology available

Calibrations are offered for the following equipment

• CONTROLLER/CALIBRATORS
Including digital pressure controllers and portable calibrators

• DIGITAL INDICATORS
Various pressure indicators including barometers

• ANALOG GAUGES
Low and high pressure analog gauges in liquid or gaseous media

• PRESSURE TRANSDUCERS
Analog or digital output transducers and transmitters

• DEADWEIGHT TESTERS
Including piston-cylinder and ball gauge types with mass adjustment when necessary

Ranges from inches-of-water to 150,000 psi

	NEW low pressure standard available for testing of mTorr and Torr range devices.
	A2LA Accreditation assures quality
	Standard 2 week turnaround time
	Accuracies as low as 0.002% of reading
	Gauge, absolute or differential pressures

Troemner Thermal Mass Flow Meter/Controller Calibration Service

Troemner is proud to introduce their new gas mass flowmeter and flow controller calibration program.  This repair, resizing, calibration and certification service is designed to meet all of your GLP, GMP, FDA, ISO, NCCLS and CLIA requirements.  Each instrument is returned to you with a detailed certificate with both tabular and graphical data to meet all necessary standards and requirements.  All services are performed in their world-class, state-of-the-art, multimillion dollar metrology lab.

Every flowmeter that they service is visually inspected for signs of wear and damage, calibrated using the most accurate flow measurement equipment and techniques available in the industry, helium leak tested and pressure checked.  These final two steps are essential to insure that all process seals have been properly seated, which can dramatically effect both the performance of a flowmeter and its safe use.

Troemner Humidity Calibration Services

Troemner humidity calibrations are traceable to the National Institute of Standards and Technology (NIST). Their facility is ISO/IEC 17025 compliant and NVLAP accreditation is pending.

Troemner’s humidity calibrations are based on the NIST proven “two-pressure two-temperature” generation process. This humidity calibration approach has been identified by NCSLI as an intrinsic/derived standard since the value of relative humidity is a mathematical relationship based on pressure and temperature. This type of humidity generation device is capable of continuously supplying accurately known humidity. Instruments are calibrated by subjecting them under test to atmospheres of known humidity at known test temperatures and test pressures
