Graphtec, Japan manufactures various high-end multi-function data loggers with a display. These data loggers are capable of measuring and recording various analogue and digital inputs.
Features of these multi-function data loggers are explained below.
This is a 8 channel multifunction data logger capable of measuring different inputs such as temperature, v
This data logger is capable of taking inputs from up to 200 channels using expansion units. It comes with a 4 GB internal memory and a display of 5.7 inch LCD. It also has a provision to insert SD card for additional memory. Also, data transfer is possible through USB and LAN ports. We can program alarm signals for each channel and it can generate external alarms. It has two models, one operating in LAN and the second one operating in WiFi. We can use it to measure Voltage, temperature, humidity, pulse, logic, AC current, power, acceleration, illuminance and CO2. It has a sampling rate from 10 ms to 2 seconds.
The basic device can take inputs from 20 channels. We can connect additional input terminals to connect up to a total of 200 channels. This makes it a 200 channel data logger. It can transmit data to a Web and FTP server.
The earlier version Gl 220 has been replaced by GL 240. This is a 10 channel handy data logger with only a weight of 500 grammes. There are 10 isolated channels and each is capable of taking different inputs. The device has 4.3 inches wide TFT screen. The sampling rate of up to 10ms can be programmed for each channel. It has a built-in memory of 4 GB through an SD card.
It can take inputs for Voltage, Temperature, humidity, pulse and logic. There are two models, one having wired data transfer and the second one having WiFi facility. This multichannel data logger has a sampling interval from 10 ms to 100 ms. We can connect all types of thermocouple inputs for measuring any temperature range.
