2B Technologies services

Please contact us through the following web form if you have any problems with your 2B Tech instruments.

The cold weather option/upgrade allows the Model 202 and Model 205 Ozone Monitors to operate down to -20°C. This upgrade includes a lamp heater and replacement of the sampling pump with a low-temperature pump. These upgrades are required for operations below about 0°C because the lamp may not turn on at low temperatures, and the polymer diaphragm becomes too stiff and causes the pump motor to burn out in standard air pumps. This upgrade was developed in collaboration with the British Antarctic Survey, which operates 2B Tech Ozone Monitors outdoors throughout the winter in Antarctica. The Cold Weather Option is available on newer instruments (those having a single long-life sampling pump) at a cost of $550. For older instruments having two sampling pumps (main and backup), please contact us for information about necessary upgrades.

We recommend that all of our instruments be calibrated at least once annually.  The calibration  includes cleaning of the entire flow path (inlet, solenoid valve(s), detection cell, DewLine™ and connecting tubing) with methanol, installation of new internal scrubber(s) and particle filter(s), and calibration to a NIST-traceable standard.  In addition, all instrument components are tested for performance (lamp intensity and precision, flow rate, etc.) and any problems diagnosed.  Be sure to return your instruments for calibration and testing prior to your next field experiment.

Subject to availability, we offer rental of refurbished Model 202 Ozone Monitors.  The minimum rental is one month ($500). A two-month rental ($900), three-month rental ($1200), and subsequent months ($500) are available.

In work supported by a NIH/NIEHS Phase II SBIR grant, we are in the process of developing an intrinsically safe version of our Hermes Personal Mercury Monitor and obtaining ATEX certification for operation in potentially explosive environments such as in oil and gas operations or in mines.  The Hermes II will have the same analytical specifications the original Hermes.
