New Automatic Isokinetic Sampler

Isostack G4 is the 4th generation of Tecora’s (Italy) isokinetic sampler. This is not an evolution, but a completely new instrument in comparison to the old models.

Isostack G4 is available in 2 versions; all in one (G4-1) and split (G4-2), both available with a 4 or 8 m3/h pump, to meet different type of use. The new functionalities of the software allow to manage the sampling in an easy and intuitive manner. The new utilities include; auto check at starting, leak test in line during sampling, duct’s library, log measurement and alarms and automatic re-start in case of flue gas velocity alarm.

Isostack G4 uses quality components which grant reliability in time. The advanced auto-test function points out anomalies and malfunctioning before starting the sampling. The new pneumatic circuit, the component’s arrangement and the removable wide carter frame, make the maintenance operations fast and easy to perform.

Isostack G4 follows quality control procedures for the automatic isokinetic sampling; each sensor and measured parameter has a calibration traceability, which is stored on the instrument’s memory and is downloadable via USB. Each sensor and acquired width has a calibration curve on 5 points. The auto-calibration function allows verification of the calibration of flow and volume measurement elements and eventually adjusts them to an external reference.

In addition, the instrument integrates a high precision pressure sensor with thermal drift compensation. Other features of the instrument are; fast isokinetic control at any stack condition, volume measurement with dry gas meter, in-stack temperature and velocity measurement, auto-test and alarm management; possibility to store up to 256 reports and reduced maintenance.
