Sensors are housed within an interchangeable ‘sensor head’ that attaches to the monitor base. Each sensor head contains a single gas or particle sensor. Swapping sensor heads takes seconds, can be done in the field, and no configuration or re-calibration is required.
Active sampling is a key design feature. Each sensor head contains a fan that works continuously or periodically (depending on the sensor type) to draw sample air to the sensor. Once sampled the air is exhausted from the opposite side of the sensor head.
The monitor base itself is a flexible electronic platform designed to fit comfortably in the hand. The monitor base comes in different models with different features.
The full-featured Series 500 has on board data-logging, has digital and analog outputs, and comes bundled with free desktop software. It can also be zero and span calibrated in the field allowing for maximum traceability.
