3. The GL840 is a multi-channel data logger manufactured by
Graphtec Corporation. It is designed to measure and record
various types of signals, including voltage, temperature,
humidity, and pulse signals. The GL840 can record up to 200
channels of data simultaneously at a high sampling rate, and it
has a large built-in memory that can store up to 2GB of data.

4. The GL2000 is also a multi-channel data logger manufactured by Graphtec
Corporation. Like the GL840, it is designed to measure and record various
types of signals, including voltage, temperature, humidity, and pulse signals.
The GL2000 can record up to 200 channels of data simultaneously at a high
sampling rate, and it has a built-in memory that can store up to 4GB of data

5. A high-speed data logger is a type of data acquisition system that is designed
to capture and record data at very high speeds, typically in the range of
kilohertz (kHz) or megahertz (MHz). These types of data loggers are commonly
used in applications such as automotive testing, aerospace testing, and
industrial monitoring.

6. A surge generator distributor is a type of electrical testing equipment used to
simulate electrical surges or transients on electronic devices and equipment. It
is commonly used in industries such as telecommunications, aerospace, and
automotive to test the robustness and reliability of equipment under different
surge conditions

7. The Graphtec Data Logger GL840 is a versatile and reliable multi-channel
data acquisition instrument designed to measure and record a variety of
signals including voltage, temperature, humidity, and pulse signals. It can
simultaneously record up to 200 channels of data at high sampling rates,
and has a large built-in memory that can store up to 2GB of data.
