MostraLog

Datalogger for temperature and humidity

Manual

Description

MostraLog is a thermohygrometer and data logger. The LCD displays the 

current temperature and humidity. The device records temperature and 

humidity to an inserted microSD-card.

MostraLog is used to monitor humidity and temperature during the storage 

and exhibition of climate-sensitive objects, such as art work or food.

MostraLog off ers accuracy of ±2% relative humidity (RH) in the range from 

10 to 90% RH, and of ±0.7°C in the range from 0 to 60°C. The device’s unique 

calibration function allows readjustment. Readjustment requires an optional 

remote control and calibration set.

An external humidity/temperature sensor can also be connected. If this is 

the case, the display shows the external sensor’s values. However, the data 

from both the internal and the external sensor are stored, making MostraLog 

a four-track data recorder.

The device’s alarm output can be connected to an alarm system. It will be 

activated as soon as the defi ned adjustable temperature or humidity limit 

values are reached.

The low power consumption provides a battery life of up to two years 

(depending on measurement interval and device settings). The data logger 

can also be powered with a standard USB power supply.

MostraLog can be mounted on a wall with two screws. When the unit is 

slotted in the wall-mount, the device itself and the microSD-card are 

protected against theft by a concealed security mechanism.

The device can be read out and confi gured via a USB cable using the PC 

software provided. However, settings can also be adjusted directly on the 

device or via an optional IR remote control.

One can also read out the data by removing the microSD-card and evaluat-

ing the data on a computer using the SD card reader.
