Thermometer RELSIB WT50 works with smartphones with iOS v7.1 and higher. Go to App Store and type “relsib” in the search box. Select “THERMOMETER SMART FAMILY” from the list of our apps and install it to your phone. Open the app.
THERMOMETER SMART FAMILY app operates in one of 2 modes: Universal and Medical. Universal is designed for long-term temperature monitoring. Also it has an option of setting 2 alarm thresholds. Medical mode has a body temperature prediction function that allows the user to obtain data within 40-120 seconds from the beginning of measurement.
App features
Body temperature can be taken in a number of ways:
Measurement results may vary: Usually body temperature measured under the armpit is 0.3-0.5 degrees lower than the temperature measured in the mouth and 0.5-0.9 degrees lower than the rectal. Body temperature measured in the inguinal fold is closer to the temperature measured in the mouth.
Body temperature measured under the armpit
This method is not used in some of the countries because it is the longest and the least accurate one. Wipe the skin with a tissue before putting the thermometer under the armpit. Thermometer has to be held in the deepest point of an armpit along the body. But the thermometer cap has to be outside. Thermometer should not be moved for the duration of measurement. When taking temperature of kids and patients in a state of unconsciousness, hold their hand until the measurement is completed. Measurement time: 4 – 9 minutes. In order to estimate the temperature quickly, use temperature prediction function.
You will obtain a predicted value within about 1-2 min. In order to obtain more accurate value, wait for the signal of measurement process completion. Normal body temperature when taken under the armpit: 35.2 – 36.7 °С.
Body temperature measured in the mouth
This body temperature measurement method is quite reliable and fast. When measuring temperature in the mouth, the thermometer probe has to be placed under the tongue to the right or to the left of its frenulum. For the duration of temperature measurement, the mouth has to be closed so that cold air cannot get into it. Measurement time: 1-3 minutes. Normal body temperature when taken in the mouth: 35.7 – 37.3 °С.
To monitor temperature during a walk and to ensure longer sleep, while at home place the thermometer under the baby’s clothes where its legs are. If it starts to increase during a walk, fold back the blankie a little bit. This way you will find optimal conditions and your baby will sleep outdoors as long as it needs to.

For example, place RELSIB WT50 thermometer under the armpit and it will immediately start to transmit temperature via Bluetooth to your smartphone or tablet with preinstalled mobile app. Universal mode is the most convenient for nighttime measurement, you can set a critical alarm threshold.
When going for a walk, place the thermometer inside the baby’s overall where baby’s legs are. Set comfort temperature alarm thresholds in the app, for example, +20…+25°С. Your phone will give you a warning if temperature is lower or higher than the normal one. And you will be able to fold back the blankie or tuck a blankie round the child in proper time.
Be sure that the baby will get the infant formula of the optimal temperature. Set the required alarm threshold in the app and place RELSIB WT50 thermometer into prepared formula. As soon as the temperature gets to the set threshold, your smartphone will inform you with audio alarm so that you can feed the baby.
RELSIB WT50 thermometer is the best present on any occasion and on no special occasion at all. This unique innovative device will become an indispensable helper in a family when it comes to temperature monitoring of anything. Due to wide measurement range and high accuracy, thermometer will be useful in many different areas. Markers of various colors will help to differentiate thermometers of every family member or by their purpose: for example, body temperature, infant formula temperature, temperature inside a fridge etc.
Thermometer WT50 is a modern choice of the people keeping up with innovation for smart homes!
It is an easy call – thermometer WT50 and people will be grateful for how much you care about them for sure!
Quite the opposite. When you take temperature under the armpit, metal tip at the probe end increases the measurement time. The thing is that metal has high thermal capacity and when it touches the skin, its surface becomes cooler.
Furthermore, at first capillaries located closer to epidermis constrict significantly and it slows down the process of skin temperature recovery. In reality, standard digital thermometer signalizes about measurement completion and then shows temperature lower than actual by 0.5 … 1.0°С because of that.
In order to take one’s armpit temperature correctly, thermometer has to be held for 5 … 10 minutes same as well-known mercury-in-glass thermometers.
Tip of RELSIB WT50 thermometer is made of plastic with low thermal capacity. At first more time is required for it to heat up, but 2…3 minutes later it leaves standard digital thermometer behind. Due to smoother time dependence of heating temperature, prediction feature can be implemented easier and be more accurate.
This is the main reason why we have designed our thermometer without metal tip. BUT there are other reasons:
Electromagnetic power of thermometer WT50 does not exceed 4 dB/mW (2.5 milliwatt), which is completely safe for kids and adults. This is 20 times lower than permitted value for pregnant women and people under eighteen years of age and substantially lower than emission from Bluetooth headsets.
Medical Bluetooth thermometer RELSIB WT50 passed all required clinical trials and has a medical certificate confirming its safety.
Every RELSIB WT50 thermometer passes individual adjustment followed by calibration at the manufacturing plant. Special liquid thermostats are used for that – temperature in them can be maintained with +/-0.03°С accuracy.
Thermometer has an accurate digital temperature sensor with maximum operating temperature of 120°С. Which means that nothing will happen to it over time and its accuracy will not be negatively affected.
Thermometer has no wire connections inside of it. All circuit elements are located on a single printed circuit board.
Consequently, thermometer has very high reliability.
It is true, thermometer WT50 has neither buttons nor indicator. This is why the thermometer body is made of a single non-allergenic material and has high sealing capacity. Thermometer turns on automatically when the probe tip starts to heat up. You do not have to turn the thermometer on additionally. Just place it on measurement point and thermometer will turn on a couple of seconds later.
