Periodic calibration of a data logger increases measurement confidence by comparing a measurement device to a traceable standard. Proper periodic calibration ensures the accuracy of a data logger throughout its life.

 

Why Calibrate?

All physical sensors become less accurate due to the environment, usage, stress, and even time. The degree to which these changes occur varies from device to device. For example, a voltage device will drift very little over the years whereas a humidity sensor can drift significantly in several weeks if subjected to a corrosive environment.

Calibration Certificates

The calibration certificates are generated at the end of the manufacturing process. Each certificate indicates the date and conditions of calibration. These certificates provide the documentation needed to satisfy most requirements, certifying that a product has been properly calibrated. The calibration certificate also provides traceability back to National Institute of Standards and Technology (NIST) standards on select models, non-N.I.S.T. available for all other models. To obtain a calibration certificate, simply  call (603) 456-2011 or e-mail Tech Support .

Calibration Services

MadgeTech’s calibration laboratory offers a variety of standard and customized calibration services. The scope of MadgeTech’s services covers the following parameters temperature, humidity, pressure, voltage, current, shock and more.

Standard calibration values and pricing can be found on the Product Information Card for each data logger. The Product Information Card can be found on the website page for that product. The standard calibration is normally a one or two point correction of the reported values, depending on the type of device being calibrated. Additional or nonstandard points incur an additional fee.

For more information on specific pricing of your data logger type or volume discounts for calibration certificates call 603.456.2011 or email rma@madgetech.com.

NIST Calibration Certificates

MadgeTech offers the following parameters for NIST calibration: temperature, relative humidity, pressure, current and voltage.

Also offered are the following non-NIST calibrations: shock (g), pH and bridge/strain.

A Certificate of Conformance is offered for the following non-calibrated data loggers Pulse, Event and State. For details on our calibration program, please contact the Tech Support.

A2LA (ISO 17025) Certification

Madgetech can supply A2LA accredited calibrations to ISO 17025 standards.

Please contact a sales representative for details on calibration abilities and pricing.

Note: This certification must be requested prior to sending the device in for recalibration.
