The compact groundwater datalogger OTT ecoLog 500 combines three features in one instrument: measurement, data storage and data transmission. The outstanding price-performance ratio is impressive - not only for qualities like longevity, precision and efficiency but also thanks to quick maintenance and comfortable handling.
Perfectly protected, all components fit into pipes from 2“. The state-of-the-art pressure probe is equipped with a rugged, ceramic-capacitive measuring cell, a precise temperature sensor and the datalogger. The communication unit at the top end of the system holds batteries and data transfer components. The two units are connected with a Kevlar-reinforced cable with pressure compensation capillary.
The data telecommunication concept of GSM/GPRS-modem and antenna allows for great versatility (HTTP, FTP, SMS…). In addition to the measured data also alarm- and status messages can be transmitted.
A clearly structured operating program with online-help simplifies the configuration and data read-out on site. The infrared-interface of the communication unit is connected with the laptop via a special reading head; contact plugs which could corrode or deform don’t exist.
Thanks to the maintenance-friendly design, the battery, SIM-card and the desiccant capsule can be changed on site without any tools. A clever power concept makes the system stupendously energy-saving. Depending on the measurement- and transmission intervals, a lithium battery pack will last up to 10 years. This saves maintenance time and reduces data loss due to power cuts. Alkaline batteries might be used alternatively.
