Measurement and recording of temperature and relative humidity for kindergartens, schools and home


What is the device for?

EClerk-M-RHT measures temperature and relative air humidity with high precision, records data at preset intervals and stores up to 260,000 values ​​(per channel) in memory. The device has a USB connector, with which you can upload data to a computer or smartphone.

With the computer software or Mobile application you can analyze data in the form of a graph or table and generate and print a Report.

With the Mobile Application you can also print the Report with a thermal printer or send it via e-mail. The recorder, connected to a smartphone, can act as a GSM modem, transmitting the measured data via GSM periodically or in emergency cases. In this case, a smartphone or tablet can act as a large screen for visualizing the current data.

Why is it important to register the microclimate parameters?

For example, every winter, children in one of the kindergarten groups began to fall ill all at a time. It got to the point that no more than 30% of children in this group were attending the kindergarten. Their parents didn’t know what to do. As they could feel, it was cold in the group. But according to the temperature measurements schedule, everything was within the normal range. Then, with the permission of the kindergarten headmaster, one of the parents brought and installed two EClerk-M-RHT temperature and relative humidity recorders, one for the play room and one for the toilet. Three days later, we looked at the data from the recorders.
It turned out that in the morning, the temperature dropped to 17 ° C in the playroom, and to 12 ° C in the toilet! It is no wonder that children fell ill after using the toilet.
Recorders allow you to print a report on the climate parameters monitoring. The recorder is included in the State Register of Measuring Instruments, so that it is no use to distrust it.
With such a report, the headmaster managed to settle the issue of an urgent wall reparation with insulation and replacement of the heating radiators just in a week. The problem was solved and the children were saved.

Why is EClerk-M-RHT
better than others?


The closest foreign likes with similar characteristics are at least 2 times more expensive!


High measurement precision for all the parameters, available only with expensive professional devices.


Archive for 520,000 values. With a recording frequency of 1 time per hour, the memory will last for 30 years!


Color and sound alarm on the smartphone (tablet) screen


Sending alarm messages by SMS and email when the parameters are outside the set thresholds


Regular sending the measurement data and geographic coordinates by SMS and email to the selected recipients

* EClerk-M-RHT logger is optimal for the long-term monitoring of microclimate parameters in residential premises. Its Report can be a forcible reason in disputes with housing and communal services, because the device is certified and included in the Register of Measuring Instruments of the Russian Federation, Belarus and Kazakhstan.

Use examples

Monitoring a child’s or a lung patient’s room will help you understand what needs to be done to improve the situation. Perhaps, it is the  insufficient humidity that causes fits of coughing in the evening and at night?

Monitoring the conditions of where children are, at school or in the kindergarten, will allow you to find out why they may often fall ill. Could it be low air temperatures and insufficient humidity that make the infection spread quickly?
