Mercury Tracker-3000 XS

Portable instrument for measuring mercury in air and other gases

The new Mercury Tracker-3000 XS

- lighter
- smaller
- more comfortable

We updated the well-proven Mercury Tracker 3000 IP!

The new Mercury Tracker-3000 XS weighs even less, it is smaller, easier to handle and features GPS, a 5.7" color TFT display and new high performance Eneloop battery pack with minimized self-discharge.

Needless to say the benefits of the old Tracker were not discarded.

Applications

Avoid problems related to mercury contamination!
The Mercury Tracker-3000 XS is a leightweight, compact and rugged instrument with built-in GPS for measuring the mercury concentration in air. Applications include:

Two examples:

Conoco Phillips in Norway

The Tracker in a hazardous waste deposit

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 Mercury Tracker-3000 XS uses a high-frequency driven electrodeless mercury discharge lamp (EDL) as UV source. It generates emission lines of an extremely narrow bandwidth which are congruent with the absorption lines of the Hg atoms to be measured. Cross-sensitivities are thus minimized.

Contrary to gold film based systems, the Mercury Tracker-3000 XS shows virtually no interference to hydrogen sulfide or water vapor. The extremely high stability of the UV source is a result of the reference detector method which is applied in the Mercury Tracker-3000 XS. Total background noise is less than 0.1 μg/m³.

To prevent temperature drift both the lamp unit and the detectors are temperature-stabilized.

The instrument is factory calibrated before delivery. The calibration remains stable over a long period of time.

Special features

Easy to operate

The user controls the Mercury Tracker-3000 XS by menu-guided inputs on a waterproof membrane keypad and a 5.7" TFT graphic display with LED backlight. After switch-on the light source is stabilized (approx. 1 - 5 minutes) and the baseline is automatically adjusted by the auto zero function. Measurement starts automatically, continuously indicating the mercury concentration of the air as a numerical value and a graphic bar.

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

Software Hg-Transfer

The device also features a serial interface (USB) as well as bluetooth for data transfer to a PC. All data can be saved as ASCII or EXCEL®-files. The necessary software (Mercury Instruments Hg-Transfer) is included.

The newly updated version now features a graphical window presenting the measurements in a clearly laid out preview.

Mobile use

The Mercury Tracker-3000 XS runs at least seven hours on rechargeable 12V Eneloop batteries. For longer employments the battery pack can quickly be swapped for fully charged spare batteries (additional Eneloop battery packs as option).
With an optionally available cigarette lighter adapter the instrument can be powered by the car battery or another 12V DC source.

The comfortable shoulder strap allows for easy field work without fatigue. The included telescopic probe makes it easy to measure the areal distribution of mercury concentrations. The probe can be stowed away in a separate bag.

Data logger with GPS

The data logger saves the measurements to a built-in 4 GB SD card.

The Data logger allows for an automatic and continuous storage of the measured concentrations. The interval between measurements to be saved can be set to a time between 1 and 999 seconds (logging rate).

Along with the concentration the saved data set includes time, date and - if desired - the geographical position (GPS).

The built-in GPS receives US-GPS, Galileo and GLONASS. This increases the accuracy of the positioning and ensures an optimized signal reception.
