The electronic control module (ECM) is the brain of a sampler. It controls the operation of the sampler.
Different models of ECM provide different mixes from among a host of functions including timing, time totalizing, flow measurement, temperature and pressure correction, blower speed control, volume computations and user interface etc. Polltech offers 7 models of ECM.
All these models are microprocessor based and are provided with with non-volatile memory to enable restoration of the sampling operation in case of power interruptions and additionally facilitates storing of the Set and Run time parameters along with other parameters.
Our ECMs are basically designed for our various samplers but with very little effort can be configured for use in conjunction with third party sampling equipment too
