Edgetech Instruments, Inc.'s calibration laboratory is accredited to the ISO/IEC 17025:2017 standard by Perry Johnson Laboratory Accreditation, Inc., accreditation number 92175. ISO/IEC 17025:2017 is the standard for which calibration laboratories must hold accreditation in order to be deemed technically competent. This formal accreditation is recognition of Edgetech Instruments Inc.'s calibration laboratory's competence.

Accreditation has been granted to perform calibrations for dew/frost point from -80°C to 20°C, relative humidity from 5% to 95%, temperature from 10°C to 50°C and pressure from 1 psia to 300 psia. To view the company's ISO/IEC 17025:2017 and ISO 9001:2015 certificates click here.

Edgetech Instruments Inc. now recertifies chilled mirror hygrometers made by other major manufacturers in addition to their own instruments. All recertifications and calibrations are performed against NIST traceable standards in Edgetech Instruments' accredited calibration laboratory.

Calibration services include:

• Recertification of all Edgetech Instruments chilled mirror sensor hygrometers and analyzers.
• Recertification of chilled mirror sensor hygrometers and analyzers made by other major manufacturers.
• Calibration of all Edgetech Instruments absolute and relative humidity devices.
• Calibration of all Edgetech Instruments oxygen analyzers.
• Repair of all Edgetech Instruments hygrometers, analyzers and devices.
• NIST traceable recertification (Certification typically expires in one or two years depending on specific industry regulations).

Calibration/Recertification capabilities include:

• Chilled mirror sensor based dew/frost point hygrometers and analyzers
• Polymer sensor based relative humidity hygrometers
• Phosphorus pentoxide sensor based hygrometers
• Lithium chloride sensor based hygrometers
• Metal oxide sensor based hygrometers
• Fuel cell sensor based oxygen concentration analyzers

ISO/IEC 17025:2017 accredited ranges:

• Dew/frost point: -80°C to 20°C
• Relative humidity: 5% to 95%
• Temperature: 10°C to 50°C
• Pressure: 1 psia to 300 psia

Calibration/Recertification is normally performed using air as the carrier gas. Inert gases and custom gas blends may be used as the carrier gas when requested.

Turnaround time is typically one to two weeks.
