5 reasons to choose a calibratable (adjustable) instrument

In this article, find out why we offer the option to purchase a calibratable (adjustable) instrument (-CAL) and why it could suit you.

7 tips for comparing two instruments accurately

In this article, we present 7 key elements to check when comparing measurements between 2 instruments to avoid diagnostic errors that can be costly to the progress of your project.

Documentation of the 3-point user-calibration mechanism

Discover how user calibration in 3 points is implemented in your calibratable products (products with the -CAL suffix).

Digital barometers

A digital precision barometer is used to calculate altitude, and if there is a temperature compensation mechanism, the data returned is more accurate.

How to measure atmospheric pressure?

The atmospheric pressure is an absolute pressure measured by a barometer. The sensors for the different types of pressure and the main barometers are explored.

USB barometer: some applications

A barometer measures atmospheric pressure. Data logging is made easier when the air pressure sensor is integrated into a USB port.

Data harmonization and why automate it

Logging data from several sensors leads to the need to harmonize this data. A DAQ system makes it possible to do this automatically.

Calibration or adjustment?

What is a calibration? In common usage, calibration consists in correcting the value given by an instrument during a measurement. It is in fact an adjustment, as per the International Vocabulary of Metrology. See some explanations and what Dracal offers.

Sensor or measuring instrument: what does Dracal offer?

Dracal Technologies offers USB measurement instruments, whose main component is a precision sensor to acquire environmental data.

What Is the Traceability of an Instrument?

The traceability certificate ensures precision and accuracy. It is provided by an accredited laboratory using instruments with documented calibration.

Data logger or data acquisition system: What is the difference?

The data acquisition system is a powerful integration and visualization tool for recording temperature, atmospheric pressure, relative humidity, etc.

Where Are QTenki, usbtenkiget and the Others?

In June 2022, we rebranded our visualization, logging and data integration tools for our instruments. See how this change will impact (or not!) our current users.

What is relative humidity and why is it important?

An intuitive description of relative humidity, its behavior in relation to changing environmental factors and its importance in both general and specific applications.

Calibrating your USB sensor: 5 advantages of opting for the 3-point user-calibration mechanism

The math channels available in our visualization and logging software allow you to implement formulas involving the various channels of Dracal USB sensors. In particular, the implementation of functions “equivalent” to a calibration can be implemented manually and be accessible in the graphing and logging tab. Why would you then choose a device (-CAL) that […]

Tutorial to install the BAR20-N in Expedition

This article explains step-by-step how to connect and configure the BAR20-N barometer with Expedition software, for effective use in navigation and sailing.

Measuring Relative Humidity: 15 Do’s and Don’ts

Presentation of 15 recommendations for measuring relative humidity with our precision electronic hygrometers.

Relative Humidity Data: Why Is Temperature Necessary?

Relative humidity and temperature sensors are fairly common. Why? Knowing the temperature and the relative humidity is useful to avoid condensation.

How to log temperature data from a type K thermocouple in less than 3 minutes?

The Dracal USB adapter of a type K thermocouple allows to quickly log, integrate and visualize precision data.

Traceability certificates and calibration

We can provide traceable certificates for most of our products. This page describes what standards our certificates meet and outlines the process of ordering them.
