Tekran - Model 3310Xi for 3300Xi HgCEMS -Elemental Mercury Calibration Unit

Model 3310Xi Calibrators can be supplied certified, with mercury outputs traceable to NIST.

• Output concentration range: 0.5 – 1300 μg/m3
• Calibration gas delivery rate: 2 – 30 SLPM
• Hg source control range: 4.00 to 40.00 °C
• Mercury source will last for many years

The Tekran® Model 3310Xi Elemental Mercury Calibrator allows high level mercury monitoring systems to be accurately calibrated using elemental mercury. It integrates seamlessly with the Tekran® Series 3300Xi speciating CEM, however it can also be used as a stand-alone mercury calibration system. The calibration source allows both multi-point calibrations and standard additions to be automatically initiated. The unit generates concentrations of mercury by using a NIST traceable temperature controlled saturated mercury vapor source. Precision mass flow controllers are used to dilute the output of this source to the desired value. The unit is capable of continuously generating large flow rates of calibration gas at virtually no ongoing cost - unlike expensive mercury calibration gas cylinders.

The Model 3310Xi incorporates technology originally developed for the Model 2505 Manual Calibration Unit. Unlike other saturated sources, the Model 3310Xi contains a host of advanced features that provide superior accuracy and allow unattended, remote operation.
