Ecoprobe 5 – Specifications

ECOPROBE 5 is the highly sensitive, portable multi-function analytical system which provides optimum power & flexibility for efficient, low-cost Soil Contamination Surveys / Toxic Gas Monitoring with the following features:

Simultaneous in-situ measurement of using the time integrated photo-ionization analyzer (PID) and 6-channel selective infra-red analyzer (IR).
Automatic re-zeroing before each measurement ensures perfect baseline stability and high accuracy of the resulting values.
Ruggedized, light-weight and compact of strong construction making it entirely suitable for the field environment.
Easy to read graphic display, user-friendly operating system & data acquisition software.
Real time correction of measured values for soil porosity, atmospheric / pumping pressure and temperature.
Automatic Monitoring Station Mode without any additional hardware/software. Automatic logging of all measured data.
A powerful surface data logging system for transparent and fast 3-D graphic visualization.
Fully integrated automatic GPS Position Logger (up to centimeter accuracy) is referenced to the WDS 84 coordinate system and also supports surface format “in meters” for un-demanding operator navigation.
An integral user calibration facility provides on-site fast calibration and advanced whole dynamic range calibration.
IrDA/RS232 interface with Win9x/NT4.0 /2000 compatible ECOPROBE_VIEW software, providing data transfer, graphic data acquisition and data spreadsheet for 3-D graphic outputs.
Reliable Oxygen reading.
Automatic date/time record for all stored data, built in adjustable acoustic alarm for all measured values.
