Refrigerator thermometer RG41 maintains constant environmental conditions and improves sealing ability

RG41, a film cable temperature sensor that boasts strong airtightness (sealing power)

From the name ZeroleakRadionode's exclusive temperature sensor RG41is a sensor created to effectively measure the internal temperature of equipment.

An NTC or PT100 temperature sensor is connected to the end of a film-type cable as thin as a snack wrapper, so there is no gap in the door even when the sensor is placed inside the equipment and the door is closed.

Therefore, it is possible to maintain a constant environment for important equipment such as equipment that requires low temperature maintenance or incubators that require internal gases to be kept constant (no external leakage). 

It also prevents moist air from entering through door gaps and forming frost, thus extending the life of the refrigerator.

The optimal refrigerator temperature sensor that can be used without glycerin, RG41

In general, pharmaceutical and bio companies use glycerin to avoid sudden temperature changes observed in temperature sensors every time the door of low-temperature equipment is opened and closed. 

So Radionode designed a temperature sensor that does not require the preparation of empty bottles and glycerin for user convenience and easy maintenance.

Radionode RG41 Zerolic Temperature Sensor is a glycerin-free temperature sensor. 

Because it is designed to respond slowly to rapid temperature changes, the temperature inside low-temperature equipment can be efficiently monitored without having to submerge the sensor in glycerin.
