Applications

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:

Mercury Instruments
  • Safety at work
  • Exhaust gas survey
  • Environmental monitoring
  • Mercury spills screening
  • Hazardous waste inspection
  • Investigation of contaminated sites
  • Investigation of mercury contamination in air
  • Measurement of mercury in scietific research

Measuring principle

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.

Analytical Performance

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.

Design Features

Mercury Instruments
  • Rugged and noncorrosive ABS case
  • Waterproof keypad and cable connectors
  • Comfortable shoulder strap
  • Wand with ergonomic grip
  • Operates five hours on fully charged batteries
  • Membrane pump with long service life
  • Sample input filter at tip of probe
  • Unsurpassed stable optical bench
  • Factory-calibration with long-term stability

Easy to operate

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) for transfer of data to a PC.

In case of a malfunction the operator of the Mercury Tracker 3000 IP is warned via messages on the display.

Mobile Use

The Mercury Tracker 3000 IP is ideal for field use. 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.
