Socket(s) for K/T thermocouples (-200 to +200°C). Ideal for low temperatures and liquid nitrogen storage vessels.
'D' Indicates LCD display. Last digit indicates number of inputs.
The GenII M series retains the standard GenII transmitter specification and adds 12,000 readings of built-in backup memory. The memory is used in continuous overwrite mode. This means many weeks of data can be held in the transmitter, depending on the number of channels in use.
GD24 with visual and delayed audible alarm (High and Low alarm level can be set in the Darca software). With display.
Sockets for 4 x K (-200 to +1200°C) / N (-200 to +1300°C) thermocouples. With display.
Sockets for 4 x R thermocouples (-200 to +2000°C). With display.
Sockets for 4 x K/T thermocouples (-200 to +200°C) with relay galvanic isolation.
GD21
If you require sensors, please order them separately.
This kit enables fitment of the transmitter's built-in wall bracket to difficult or uneven surfaces. The kit provides additional docking security.
