The 9009 allows you to calibrate hot and cold temperatures at the same time. The hot block provides temperatures from 50°C to 350°C, while the cold block covers the range -15°C to 110°C. Each block is controlled by a precision temperature controller. Each block has two wells with removable inserts.
You are able to calibrate four probes at once or two probes at the same time with an external reference. The unit is housed inside a watertight and airtight case, and weighing only 4.5 kg makes means it is easy to transport.
