Graphtec GL100-N
Petit Channel Data LoggerThe Graphtec GL100-N Petit Channel Data Logger can monitor up to 4 channels of input data depending on the input module/sensor connected to it.
This logger allows you to change the input variable via a range of input sensors allowing you to move quickly from one application to another as and when required. Popular measurement ranges include DC voltage levels from 0…20mV to 0…50V and process signals such as 1…5V or 4…20mA, temperature measurements from type K & T thermocouples, carbon dioxide plus Illuminance (Lux) & Ultraviolet levels can all be monitored with the Graphtec GL100-N Petit Channel Data Logger.
- 4 channel DC Voltage Measurements across 12 ranges from 0…20, 50, 100, 200, 500 mV, 1, 2, 5, 10, 20, 50V plus 1…5V. When used in conjunction with Graphtec GS-4VT Voltage & Temperature input terminal. (4 channel 4…20mA Measurements are also possible by adding a 250Ω resistor across the pos/neg terminals and choosing the 1…5V range).
- 4 channel Temperature Measurements from type K & T thermocouples when used in conjunction with Graphtec GS-4VT Voltage & Temperature input terminal.
- Temperature & Humidity Monitoring is also possible when used with the Graphtec GS-TH Temperature & Humidity Sensor.
- Carbon Dioxide monitoring is possible when used with the GS-CO2 Carbon dioxide Sensor.
- It’s even possible to monitor Illuminance (Lux) & Ultraviolet levels with the Graphtec GS-LXUV Sensor.
- The Graphtec GS-DPA allows you to monitor two different variable at the same time you just need to choose your sensors, compatible sensors include Graphtec GS-TH Temperature & Humidity Sensor, GS-CO2 Carbon dioxide Sensor or the GS-LXUV Illuminance & Ultraviolet Sensor.
- Sampling intervals of 0.5secs to 60 minutes.
- Built in memory of 4.9MB can support single channel monitoring at 1 minute interval for approx. 1 year. For faster intervals and multichannel monitoring a standard 2GB micro SD memory card can be added.
- The supplied GL100 Application Software allows you to view data in waveform or digital format.
- Battery Life is approx. 2 weeks with single channel monitoring at a 1m sampling interval.
- The GL100 can also be powered by an optional AC adaptor or a PC via USB to micro USB cable.
