Data logger products and how to use them.

Introducing the GL840 Data Logger

DATAQ Instruments is pleased to introduce the third-generation GL840 data logger. Replacing the now obsolete GL820, the GL840 features 20 isolated analog channels, with optional expansion up to 200. Each channel can be individually configured to acquire voltage from ±20mV to ±100V full scale, or temperature, with support for K, J, E, T, R, S, B Read More

Introducing the GL240 Data Logger

DATAQ Instruments is pleased to introduce the third-generation GL240 data logger. Replacing the now obsolete GL220, the GL240 features 10 isolated analog channels that can be individually configured to acquire voltage from ±20mV to ±100V full scale, or temperature, with support for K, J, E, T, R, S, B and N-type thermocouples. In addition, four discreet Read More

Stumbling Blocks to Stand-alone Data Logging

Data Acquisition > Stand-alone DATAQ Instruments’ DI-710, DI-718B and DI-718Bx series data loggers include a stand-alone option. A built-in SD memory card slot allows you to acquire data to a standard SD card (2GB max. capacity), without being tethered to a PC. When setting up your instrument to acquire data in stand-alone mode, there are Read More

Transmitting Data From Your EL-WIFI Series Data Logger

Data Logger > Wireless > EL-WiFi Series There’s been some confusion with with regard to EL-WIFI series data loggers and the way that they transmit temperature & humidity data back to the PC. In order for an EL-WIFI series logger to remain connected and continually transmitting data, the logger must be in range of the wireless Read More

Dual-Channel Wireless Temperature Data Loggers

Data Logger > Wireless DATAQ Instruments is pleased to introduce the EL-WIFI-DTC and EL-WIFI-DTP+. These dual-channel wireless (802.11b compliant) temperature data loggers are capable of buffering over 1,000,000 temperature readings and transmitting that data to a PC via a WiFi router. The EL-WIFI-DTC can acquire temperature from -270 to 1300°C (-454 to 2372°F) using J, Read More

EL-USB Battery Issues

Data Logger > USB > EL-USB We’ve noticed an uptick in the number of customers reporting that the batteries included with their EL-USB series data loggers are ‘dead on arrival’. The battery included with most EL-USB series loggers is a 3.6V (½AA cell) lithium metal battery. The problem can occur when a battery is unused Read More

Sub-zero Thermocouple Measurements

Data 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
