Avoid problems related to mercury contamination ! The Mercury Tracker 3000 IP is a leightweight, compact and rugged instrument for measuring the mercury concentration in air. Applications include:
The mercury concentration is measured in an optical cell entirely made of a high purity grade fused silica. A maintenance-free membrane pump continuously feeds the sample gas into the measuring cell where the attenuation of a UV beam is measured. Analytical wavelength used is 253.7 nm.
This measuring method is called "Cold Vapor Atomic Absorption Spectrometry" (CVAAS) , which is extremely sensitive for mercury determination and is widely used for many years.
The Tracker-3000 IP uses a high-frequency driven electrodeless low pressure mercury lamp as UV source. This lamp emits lines of an extremely narrow bandwidth which are congruent with the absorption lines of the Hg atoms. Cross-sensitivities are thus minimized. The extremely high stability of the UV source is a result of the reference beam feedback control method. Total background noise is less than 0.1 µg/m³.
The instrument is calibrated before delivery and keeps the calibration for a long period of time. For quality control a test screen is included allowing the user to check calibration.
The user controls the Mercury Tracker-3000 IP by menu-guided inputs on a waterproof membrane keypad. After switch-on the light source is stabilized (approx. 1 - 5 minutes). Measurement starts automatically, continuously indicating the mercury concentration of the air as a numerical value and a graphic bar. The baseline is automatically adjusted by the auto zero function.
The measurement data are displayed on an LCD in real time, both numerically and graphically. The device also has a serial interface (RS 232 / USB) for transfer of data to a PC. All data can be saved as EXCEL®-files. The necessary software is included.
In case of a malfunction the operator of the Mercury Tracker 3000 IP is warned via messages on the display.
The Mercury Tracker 3000 runs at least four hours on battery power. For longer employments the battery pack can quickly be swapped for fully charged spare batteries. With an optionally available cigarette lighter adaptor the instrument can be powered by the car battery. The included probe allows to check spots or to screen areas for mercury concentrations.
The comfortable shoulder strap allows for easy field work without fatigue. The probe makes it easy to measure the areal distribution of mercury concentrations. The probe features an ergonomic handle and is easily demountable. It can be stowed away in the top cover of the instrument.
