The Graphtec GL840-M-PORTABLE-BUNDLE is a 20 channel Thermocouple/Voltage Midi Logger. The kit includes a B-568 Wirless unit, Battery Pack and Pelican Case. The Graphtec GL840M Portable Bundle contains a highly isolated input system which ensures that signals are not corrupted by noise from other channels. The GL840M Portable Bundle`s inputs are suitable for temperature measurement with multiple channels.

The standard configuration has 20 analog input channels. However, it can be expanded up to 200 channels by adding optional 20 channels extension terminal base units (B-566) and input terminal units(B-564 or B-565).

Input terminal blocks can be connected directly (in daisy chain), or using the B-565 cables. This allows the input terminals to be placed in separate locations according to the need of the application. The input terminal unit and the GL840MPortableBundle main body can be extended by using an extended connections cable.

Maximum sampling interval of up to 10 ms

Provides faster sampling rates for voltage measurements. You are able to achieve up to 10 ms sampling speed when limiting the number of channels in use.

Supports large-size SD memory card for reliable long term measurement

The GL840-M-PORTABLE-BUNDLE carries two SD memory card slots for storage device. The SDHC type SD memory card is supported up to 32 GB. The captured data can be stored in GBD(Graphtec binary data) or CSV file format.

Protect your GL Investment

The IP67 rated case protection and form fitting foam allows the GL840 to be safely transported to field locations and are perfect for electrical contractors and field technicians.

What you can do using the wireless LAN

Combining GL100-WL and GL840:
GL100-WL can now be connected to the GL840 as a remote sensor using the WLAN feature. You can expand your measurement variety by adding the sensors available on the GL100-WL unit (sold separately). The measured value by GL100-WL will appear in a single file along with the measurement value from the GL840 main inputs. GL840 will now take in direct information from the GL100-WL units.GL840 supports up to five units of the GL100-WL.
