The Graphtec GL240 data logger is a compact, standalone 10-channel logger that accepts voltage, temperature, humidity, pulse and logic signals. In addition to accommodating numerous measurements, the GL240 includes many communications options and advanced functions making it an incredibly versatile data acquisition instrument for a wide array of applications.

The GL240 features 10 channels, isolated so that wiring errors or overloaded channels do not affect neighboring channels. Two SD card slots support up to 32GB of memory which can hold over a year's worth of data depending upon the sampling rate. A full color, 4.3-inch TFT display allows user to view data in waveform or digital form while also displaying parameter settings.

The Graphtec GL240 includes a number of communications features which allows integration with other devices and easy file sharing. A wireless LAN module (B-568) can be added to connect the GL240 with Graphtec GL100-WL modules. This expands the measurement variety of the GL240 by utilizing sensors available to the GL100-WL which will relay data directly to the GL240. The GL240 can also be connected to a LAN via a WLAN access point. Measured data can then be monitored via a PC or smart device using the application software. Configuration can also be set via the network.

Here's how some of our customers use this product...

Data Logger for Combustion Testing

The Background: Our customer designs and manufactures wood-burning stoves. During the testing phase of designs, they require a range of data points—including multiple surface temperature measurements, carbon monoxide levels, particulate measurements, and stove weight—be simultaneously logged.

The Problem: The customer had previously used a number of data loggers to record all the measurements they needed. This resulted in a bit of a mess with loggers, wires and sensors all vying for space while technicians had to keep track of what was doing what. The customer needed a better solution.

The Solution: We recommended the Graphtec GL240 data logger, a compact, standalone 10-channel logger that accepts voltage, temperature, humidity, pulse and logic signals. In addition to accommodating numerous measurements, the GL240 includes many communications options and has the input flexibility to accommodate both the TC inputs and the Analog inputs. The customer was also happy with the ability to run the unit either autonomously or tethered to a PC.
