RSS FeedsData Logger > Thermocouple “One of the best kept secrets in the instrumentation world is that sub-zero thermocouple measurements require thermocouples that are specially qualified for that application.” Looking at the specs of a typical thermocouple data acquisition system might be a little misleading when it comes to interpreting temperature measurement capability. For example Figure 1 is a Read More

Changes to the Built-in Temperature Alert Server
Data Logger > Wireless > Temperature Alert There have been some changes to the server, built into the Temperature Alert TM-WIFI350 LAN-based temperature and humidity data logger. In the past, when typing the IP address of your TM-WIFI logger into a web browser, you were directed to ‘Developer Mode’. In Developer Mode you can set alarms, Read More
Flood Sensor for Temperature Alert
Data Logger > Wireless > Temperature Alert The AC-FLDRJ is a flood sensor designed for use with the Temperature Alert TM-WIFI-350 LAN-based temperature and humidity data logger. Measuring just 2.5” x 3.25” x 1”, simply lay the sensor on a flat surface to detect the presence of conductive, non-flammable liquids. Built-in feet on the bottom Read More
WiFi Range Considerations
Data Logger > Wireless We carry several WiFi products and we’re often asked about their range. In other words, how far from the WiFi router can the data loggers be located? Unfortunately, this is like asking us to forecast the weather next Sunday. There are simply too many variables for us to predict how well any WiFi Read More
EL-WIFI-Alert Alarm Indicator
Data Logger > Wireless > EL-WiFi Series The stand-alone EL-WIFI-Alert alarm indicator is an add-on for EL-WIFI series temperature and humidity data loggers. The EL-WIFI-Alert produces an audible and visual alert when an alarm level on any of your EL-WIFI temperature and humidity data loggers (installed on the same wireless network) is breached. Note that Read More
4-20 mA Measurement Resolution
Data Acquisition > 4-20mA Current Loop Don’t overlook a vital component that affects 4-20 mA measurement success: Measurement resolution. Additional Reading: 4-20 mA Shunt Resistor and Current Loop Data Acquisition Products Measurements from sensors that have a 4-20 mA output are very common. Customers always ask how to connect them to a data logger or data acquisition Read More
Lascar’s ‘Files Thru the Air’ Technology
Data Logger > Wireless Data Loggers > EL-WiFi Series Users can manage and monitor any number EL-WIFI series instruments remotely… Lascar’s ‘Files Thru the Air’ technology allows those using EL-WIFI series instruments to store data to the cloud. Users can manage and monitor any number EL-WIFI series instruments remotely, using a web browser on their PC Read More
Boot Your Graphtec Data Logger in USB Drive Mode
Data Logger > USB > Graphtec An oft-overlooked feature of Graphtec data loggers is the ability to boot into USB Drive Mode. As the name implies, USB Drive Mode allows you to access, save, copy and delete files from your data logger, just as you would with a USB flash drive. USB Drive Mode Read More
Sample Up to 14.4 kHz in Stand-alone Mode
Data Logger > Stand-alone Thanks to single-level cell (SLC) technology, DATAQ Instruments stand-alone data loggers can once again sample at throughput rates up to 14,400 samples per second. Due to inconsistencies with older SD cards using multi-level cell (MLC) technology, we were forced to reduce the maximum stand-alone sample rate specification for DATAQ Instruments data Read More
Data Logger vs. Data Acquisition
Data Acquisition or Data Logger If you need to digitize an analog signal, record it, and provide a method to analyze it, do you need a data logger or a data acquisition system? It has become increasing clear that the answer is ‘Yes’ to both products. What I mean is that the traditional definitions of Read More
