Data loggers: monitor and use your measurements in natural environments

Data loggers are used to collect, store and monitor field measurements during tracing tests, hydrological monitoring campaigns or environmental surveillance. They are used when data needs to be observed over time, compared, stored historically or analysed after a measurement campaign. At Fluotechnik, we offer equipment suited to professionals carrying out monitoring in aquifers, rivers, karst networks, springs, watersheds, hydraulic structures or complex natural systems.

What is a data logger used for in hydrological monitoring?

A data logger is used to collect and store measurements taken during a field campaign. In a hydrological or hydrogeological context, it can be used to monitor the evolution of a signal, a parameter or a series of measurements over a given period. It therefore provides usable historical data for analysing a phenomenon, comparing monitoring points or interpreting a restitution. Unlike a fluorimeter, whose main role is to measure the fluorescence of a tracer, a data logger is part of a monitoring-over-time approach.

It does not replace the measurement instrument: it complements the system by ensuring the collection, storage and organisation of the information produced by the field protocol. This category is intended for engineering consultancies, hydrogeologists, laboratories, local authorities, researchers and professionals who need to structure their measurement data. Data loggers are particularly useful when measurements must be repeated, monitored over a long period or analysed after the intervention in order to better understand the behaviour of the system studied.

Our range of data loggers for field monitoring

Fluotechnik offers a range of data loggers for professionals carrying out measurement campaigns in natural environments, hydrology, hydrogeology or environmental monitoring. These instruments are used to record measurements from sensors or instruments in order to monitor their evolution over time and make the results easier to analyse. Depending on the protocol, the parameters monitored, the campaign duration, the measurement frequency and field conditions, the choice of data logger may vary. This category helps compare the available equipment according to its use, autonomy, recording capacity, compatibility with associated instruments and relevance for punctual, regular or extended monitoring.

How do you use a data logger in a measurement protocol?

Using a data logger requires a clear protocol: parameters to be monitored, recording frequency, campaign duration, measurement points, associated equipment and method for analysing the results. Its role is to secure data collection and facilitate analysis.

Step 1 - Define the monitoring objectives

Before choosing a data logger, you need to specify what you want to observe: signal evolution, restitution monitoring, parameter variation, comparison between several points or extended surveillance of a natural environment.

Step 2 - Identify the associated equipment

The data logger must be chosen according to the instruments or sensors used. It can complement measurement equipment depending on the type of data to be collected, technical compatibility, acquisition frequency and expected level of autonomy.

Step 3 - Set the recording frequency and duration

The protocol must define the measurement frequency and monitoring duration. A short campaign does not require the same configuration as long-term monitoring. These parameters influence equipment choice, storage capacity and field autonomy.

Step 4 - Install the equipment at monitoring points

Data loggers are positioned according to the objectives of the study: restitution point, watercourse, piezometer, structure, network, outlet or monitoring area. Their installation must allow reliable data collection consistent with field conditions.

Step 5 - Use the collected data

Once the campaign is complete, or during monitoring, the recorded data can be retrieved, compared and analysed. It makes it possible to visualise evolutions, identify trends, confirm a phenomenon or complete the interpretation of a measurement protocol.

Why choose a data logger with Fluotechnik?

Choosing a data logger depends on the protocol, associated equipment, monitoring duration, field conditions and expected type of analysis. Fluotechnik supports professionals in selecting equipment suited to measurement campaigns in natural environments. Our solutions help structure data collection and make the results easier to analyse in hydrological, hydrogeological or environmental studies.

Equipment dedicated to monitoring over time

Data loggers make it possible to store measurements and follow their evolution over a defined period.

Complementary to measurement instruments

They can be combined with different equipment depending on the parameters monitored and the needs of the field protocol.

Suitable for hydrological and environmental studies

They are useful for monitoring aquifers, rivers, springs, karst networks or complex natural systems.

Useful for long or repeated campaigns

When measurements need to be monitored regularly or over an extended period, the data logger helps ensure continuity of observation.

Choice guided by the protocol

The right equipment depends on the recording frequency, desired autonomy, data volume and associated instruments.

Expert technical support

Our team supports you in choosing the data logger best suited to your application and field constraints.

FAQ on data loggers

A data logger is a device that collects, stores and monitors measurements over time. It is used when information from a sensor or instrument must be kept for analysis.

It is used to monitor the evolution of field measurements, particularly in hydrological, hydrogeological or environmental contexts. It makes it possible to analyse variations, restitutions or observed trends.

A fluorimeter measures the fluorescence of a tracer. A data logger records and monitors measurements over time. The two types of equipment can be complementary, but they do not address the same need.

Yes, depending on the protocol and equipment used, a data logger can complement a fluorimeter when measurements need to be monitored or stored over a given period.

It can be used for restitution monitoring, hydrological campaigns, network surveillance, measurements in rivers, aquifers, piezometers, structures or complex natural systems.

The choice depends on the parameters to be monitored, acquisition frequency, campaign duration, desired autonomy, data volume and associated equipment.

Yes, they are particularly useful when measurements need to be recorded over an extended period or when data must be analysed after a field campaign.

No, its main role is to record data. Fluorescence measurement is performed by a fluorimeter or compatible instrument. The logger can complement this system if the protocol requires it.

Choosing a data logger for your field monitoring

A data logger is an essential piece of equipment when measurements need to be monitored, stored and analysed over time. In hydrological, hydrogeological or environmental studies, it helps structure the collection of field information and makes post-campaign analysis easier. It complements measurement instruments by adding a logic of historical storage, comparison and monitoring.

The choice of data logger mainly depends on:

  • The type of measurements to be monitored: fluorescence, level, temperature, flow rate, signal or another parameter depending on the associated equipment
  • The type of environment studied: aquifer, river, spring, karst network, watershed, structure or complex natural system
  • The monitoring objective: restitution, surveillance, point comparison, trend analysis or extended monitoring
  • The desired recording frequency
  • The duration of the field campaign
  • Autonomy, storage capacity and compatibility with the instruments used.

By creating a dedicated Data loggers category, Fluotechnik clearly distinguishes acquisition and time-monitoring equipment from direct measurement equipment such as fluorimeters. This separation makes it easier to guide professionals according to their real need: measuring a fluorescent signal, recording data, monitoring a restitution or structuring a monitoring campaign in a natural environment.
