The ECOPROBE 5 is a highly sensitive, compact, and portable analytical system that provides optimum power & flexibility for efficient, low-cost Soil Contamination Surveys / Toxic Gas Monitoring. It uniquely combines advanced PID (Photo-ionization) and IR (Infrared) technologies, replacing multiple separate devices with one rugged unit.

Measurement Capabilities and Performance:

The instrument performs simultaneous in-situ measurement, analyzing the total level of Volatile Organic Compounds (VOCs) and chlorinated hydrocarbons (PID) down to a $0.1\ \text{ppb}$ detection limit. Selectively (IR), it measures Methane ($\text{CH}_4$), Petroleum Hydrocarbons (THC), and Carbon Dioxide ($\text{CO}_2$) up to $500,000\ \text{ppm}$. It provides a reliable Oxygen ($\text{O}_2$) reading, with optional $\text{N}_2\text{O}$ and $\text{H}_2\text{S}$ measurements available. Response time is fast, between $0.1$ and $0.8\ \text{seconds}$.

Accuracy and Automation:

Automatic re-zeroing before each measurement ensures perfect baseline stability and high accuracy. The system features real-time correction of measured values for factors like soil porosity and pressure. It includes an integral user-calibration facility for fast on-site checks and an internal vacuum pump with programmable speed.

Design and Connectivity:

With a rugged, light-weight, and compact construction (only $3\ \text{kg}$), it is entirely suitable for the field environment. It has a memory capacity of about $100,000$ measurements and RS 232 / Infrared interface. The ECOPROBE_VIEW software (Windows compatible) provides data transfer and transparent, fast $3\text{D}$ graphic visualization. It includes a Fully integrated automatic GPS Position Logger (up to $\text{cm}$ accuracy) and a built-in adjustable acoustic alarm.

Monitoring Station Mode:

The ECOPROBE 5 can operate as a slave station in a wireless monitoring network. It performs repeated measurements and automatically logs data. Full remote control (settings, data download, and live measurements) is accessible via the server and the Internet, communicating through Cellular Network or Radio-Modems. The server displays stations on a terrain map and provides alarm notification if pre-set limits are exceeded.
