The VOC Data Sampler 822 is a portable, pass-through, Pocket-PC based data logger for IR, convection and other heat curing systems using solvent containing inks, glues, lacquers and paints. It is detecting organic solvent vapours, other volatile vapours and combustible gases such as carbon monoxide, ethanol, isobutanes, n-hexanes, benzenes, ethanol, acetone etc.

Due to its compact dimensions and heat resistance up to 200°C (with optional carrier) it is ideal to be used in conveyorized thermal curing ovens typically used in the printing, semiconductor and wood industry.
Via ComPort, it is connected to a PC in order to pre-select parameters for the measuring cycle.
After passage of the curing chamber the recorded data can be downloaded to a computer for further editing by a Powerful Data Acquisition Software. The measurement and recording of data takes place at user-defined intervals.

In the basic version the VOC Data Sampler 822 is equipped with one solvent detection sensor.
The solvent detection sensor has a high sensitivity to the vapours of organic solvents as well as other volatile vapours. It has also sensitivtiy to a variety of combustible gases.
Precise temperature measuring is made possible by a fast response temperature sensor (option).
An air-flow sensor is optionally available.
The sensors are built in the housing and the back of the unit serves as a heat shield.
Extra heat protection up to 200°C with separately available carrier (option)

The measuring results are displayed on graphs and show the solvent concentration in ppm as well as the temperature curve during the measuring cycle in °C. The monitor displayed graphs show the complete profile and offer zooming and auto scale functions. Measuring values are also displayed as digital numbers.
