Graphtec GL100-WL Data Logger

The Graptec GL100 is a small, light-weight series of data loggers. Each model can be powered by batteries and/or by an external power source. Measurements can be recorded over a long period of time, depending on the power saving settings. Each model is easy to set-up. Its small size allows measurements to be taken from almost anywhere. Remote control and monitoring is possible using the GL100-WL, with W-LAN. A variety of sensors are available for different types of measurements.

Standard accessories… Quick start guide, CD-ROM (user manual & application software), USB cable (MicroB-A ~0.5m).


  • Small size for user convenience.
  • Record data using the internal memory and/or a microSD card. The recorded data can be transferred directly to a computer via USB or via wireless on the GL100-WL model.
  • Meets IP54 standards for basic water resistance and dustproofing – Suitable for a wide range of measuring environments.
  • Powered by commercial batteries (two AA alkaline batteries) and/or an external power source (N.B. Some sensors have power source restrictions).
  • Alarm indication via LED and output terminal.
  • LCD for checking condition settings and measurement data.
  • Simultaneous measurements of temperature (-20°C to 85°C) and humidity (0% to 100% R.H.) measurements (sensor GS-TH).
  • Simultaneous measurements of voltage (20mV to 50V and 1V to 5V), temperature (K and T type thermocouples) and logic/pulse signals (sensor GS-4VT).
  • 4-channel thermistor terminal module, connected to the appropriate thermistor sensor, for up to 4-off temperature measurements (-40°C to 105°C and -40°C to 120°C). It can also measure 4-off logic/pulse signals (sensor GS-4TSR).
  • Acceleration (2G, 5G and 10G) can be measured in three directions using the 3-axis acceleration / temperature sensor (GS-3AT). Temperature (-10°C to 50°C) can also be measured at the same time with the 3-axis acceleration / temperature sensor’s internal temperature sensor.
  • Voltage can be measured for single-phase two-wire systems, single-phase three-wire systems, three-phase three-wire systems, etc. by using the AC current sensor adapter and AC current sensor (GS-DPA-AC and GS-AC**A).
  • Illumination (0 to 200,000 lx) and ultra violet rays (0 to 30 mW/cm2) can be measured at the same time using the illumination / ultraviolet sensor module (GS-LXUV).
  • CO2 (0ppm to 9999ppm) can be measured using the CO2 sensor (GS-CO2).
  • Two sensors can be connected from among the GS-TH, GS-CO2, and GS-LXUV and perform a combined measurement by using the branch adapter.


Measurement Data
Number of channels Varies by the input module used, and measurement type is fixed with each input module
Input method, Type of input terminal Varies by the input module used, and measurement type is fixed with each input module
Output signal Alarm (1 channel), solid state switch with optical isolation (Optocoupler, Max. load is the 30 V, 50 mA)
