Instrument Calibration & Repairs

All sensors and instruments require routine calibration to ensure your measurements are accurate and performing within manufacturer standards. We recommend that all air monitoring instruments be calibrated at least once annually. Be sure to return your 2B Tech instrument for calibration and/or repair prior to your next field experiment to maintain peak performance and the most accurate results.

Service IncludeS

Instrument calibration services with 2B Tech includes cleaning of the entire flow path (inlet, solenoid valve(s), and detection cell) with methanol, and installation of new internal scrubber(s) and particle filter(s).

Upon receiving your instrument for calibration service or repairs, it will be evaluated to see if it requires any additional repairs above and beyond our base service. If applicable, a separate, preliminary service quotation will be sent out for your approval.

Deep Cleaning

Entire flow path is cleaned with methanol.

Part Replacement

New scrubber assembly  installed.

Testing

All components tested & any issues diagnosed.

f

Calibration

Calibrated for optimal performance.

Service Guide

How to get your instrument calibrated and/or repaired with 2B Tech.

Submit the Tech Support web form below to open a service ticket for calibration and/or repairs on your instrument. Be sure to provide both the serial and model number of your instrument.

If you are experiencing problems, it will greatly aid our troubleshooting efforts if you would:

 

  • Use the serial connection of the instrument to capture some raw data;
  • Save the (raw, unmodified) data in a text file;
  • Upload the file as an attachment and submit it with your service ticket.

Our tech support team will respond with an RMA form, RA number, and instructions for shipping your instrument back to 2B Technologies for calibration and/or repair.

Please fill out the RMA form according to the instructions outlined by our tech support team and include it in the shipment of your instrument back to 2B Technologies.

Once the instrument has been received by 2B Technologies, it will be evaluated to see if it requires any additional repairs above and beyond the base calibration and/or repair service that caused the instrument to be returned to us. If applicable, a separate, preliminary service quotation will be sent out for your approval.

After the preliminary service quotation has been approved, we’ll send a confirmation with an expected return ship date for your instrument. Then the calibration and any necessary repairs will be completed prior to shipping back your instrument.

Calibration Method

An overview of 2B Tech calibration service types and methods.

NIST-Traceable Ozone Calibration

Based on a calibration provided by the U.S. National Institute of Standards and Technology (NIST), 2B Technologies designates the calibration of all Ozone Monitors (with the exception of high concentration ozone monitors) to be NIST traceable through an unbroken chain of comparisons.  The transfer standard is used to calibrate the working standard, which in turn is used to calibrate the customer’s instrument.

IOA KI Method Ozone Calibration

We designate the calibration of all our High Concentration Ozone Monitors and Aqueous Ozone Monitors to be traceable to the International Ozone Association (IOA) KI Method. In this process, our High Concentration Ozone Monitors are calibrated in the 0-5 Wt.%O2 range (0-20 ppmw for Aqueous Ozone Monitors) based on traceability to the KI method.

NIST-Traceable NOx Calibration

The calibration of all 2B Technologies NO2/NO/NOx is traceable to NIST through a Transfer Standard for ozone.  A NIST-traceable concentration of ozone is reacted quantitatively with a standing concentration of NO in a gas phase titration (GPT) according to the reaction: NO + O3 -> NO2 + O2. The depletion of NO measured by the NO2/NO/NOx Monitor provides the calibration for NO.

NIST-Traceable Black Carbon Calibration

The calibration of all 2B Technologies Black Carbon Photometers is traceable to NIST through a Transfer Standard for ozone.  A NIST-traceable concentration of ozone is reacted quantitatively with an excess of NO provided by a compressed gas cylinder in a gas phase titration according to the reaction: NO + O3 -> NO2 + O2 to calibrate a Model 405 NO2/NO/NOx monitor which is used as working standard.  The 405 nm channel of the Black Carbon Photometer is then calibrated with NO2 relative to the working standard.  The 880 nm channel is then calibrated relative to the 405 nm channel using aerosolized 500 nm diameter polystyrene latex spheres (PSLs).

NIST-Traceable Mercury Calibration

Calibrations of all 2B Technologies mercury monitors are traceable to NIST through an unbroken chain of comparisons.  The transfer standard is used to calibrate the working standard, which in turn is used to calibrate the customer’s instrument.
