Compact light instruments, are ideal for measurement and record of signals, they are intended for the measurement and the writing into the memory of the values of the temperature before different time intervals with the use of the built-in or external sensor.
3632-20 this is the registrar, that has the watertight construction with the built-in sensor.
3633-20 this the registrar, that has the built-in sensor or is possible the connection of external sensor (option).

• Large volume of internal storage, to 16000 elements of data.
• Possibility of connection based on PK on the means USB or RS-232 (option) and graphing regarding the obtained values.
• Possibility of the automatic writing of the measured values into the memory of instrument during the long time, through the established time intervals.
• Data remain before the memory of instrument, even when battery is discharged.
• The presence of the function of power of save (savings of energy), function makes it possible to increase the duration of record.
