100 to 50 °C 27 minutes<br />
Immersion depth: 150 mm (dry-<strong>block</strong>)<br />
150 mm (liquid-bath)<br />
Resolution (user selectable): 1 °C or 0.1°C or 0.01°C<br />
Interface: RS232<br />
Instrument weight: 10.8 Kg<br />
Instrument dimensions (L x W x H): 352 x 156 x 360 mm<br />
MVI – Improved temperature stability MVI stands for „Mains power Variance Immunity”<br />
Dual-zone heating <strong>block</strong><br />
The specialized <strong>block</strong> design increases the<br />
temperature homogeneity in the critical<br />
calibration zone. It also minimizes the need to<br />
insulate the sensor-under-test and makes it<br />
possible to calibrate liquid-filled and other<br />
mechanical sensors.<br />
The main, or lower, zone ensures optimum heat<br />
dissipation throughout the entire <strong>block</strong>. The<br />
secondary, or upper, zone compensates for the<br />
heat loss from the top of the <strong>block</strong> and from the<br />
sensor-under-test<br />
