Graphtec GL220 midi logger

The Graphtec midi logger GL220 is claimed to set a new benchmark in general-purpose data loggers.

It has all the features of a data logger, together with quality and high performance.

It has 10 isolated channels each with multifunction input. The isolated input system ensures that signals are not interfered with by sensors connected to other channels. It has big capability and can capture voltage, temperature, humidity and pulse as well as logic signals.

It can also record fast changes and provides faster sampling rates for voltage measurements and can achieve a 10 ms sampling interval when the number of channels in use is limited.

The device also features an optional ring memory that allows users to continuously save the most recent data, via its 2 GB flash memory that enables secure long-term data measurement without the need for external storage. If external storage is required, the logger can save measured data to a USB memory stick that can be replaced during measurement without data loss.

Its standard software captures data that is compatible with Windows XP, Vista and Windows 7 and can be converted for use in Excel.

The GL220’s clear and enhanced 10.9 cm (4.3″) wide TFT colour LCD monitor, lets users easily read data in waveform or digital form and set measurement parameter settings.

It uses a re-chargeable 6-hour battery and standard accessories include an AC power adapter, USB cable, Windows graphical software and a plastic carry case with foam insert.
