BALDRTHERM B0598 3-channel thermohygrometer with automatic backlight

The BALDRTHERM B0598 thermohygrometer allows you to monitor temperature and humidity in up to four locations simultaneously – indoors and using three outdoor measurement channels. It features automatic backlighting that adjusts brightness based on ambient light conditions, temperature and humidity alarms, and a clear display that shows all measurements in one place. With a transmission range of up to 100 m, you can conveniently monitor conditions in different parts of your home or building.

Monitoring conditions in multiple locations simultaneously

The B0598 model allows you to simultaneously monitor temperature and humidity in four locations – indoors and via three independent measurement channels. This solution is ideal for use in bedrooms, children's rooms, greenhouses or storage rooms, among others, as it allows you to conveniently compare conditions without switching between devices.

Automatic backlight adjustment based on ambient light

The device uses a photovoltaic light-sensitive panel that automatically adjusts the brightness of the display's backlight based on the ambient light level. As a result, the display remains clearly visible during the day and emits a softer light after dark. The manufacturer has also included energy-efficient solutions that reduce power consumption.

Temperature and humidity alarms

The thermo-hygrometer is equipped with alarm functions for each of the three measurement channels. The user can independently enable or disable notifications for channels CH1, CH2 and CH3. If the set values are exceeded, the device warns the user with a flashing display, allowing for a quick response to changing conditions.

Intuitive operation and convenient management

The buttons located on the sides of the housing provide quick access to the most important functions. From there, you can switch between measurement channels, activate pairing mode, view stored maximum and minimum values, switch between °C and °F temperature units, and turn the automatic backlight on or off. Separate alarm buttons for each channel simplify device configuration.

It is important to know

When choosing a combination thermohygrometer like this model, it is important to understand how usability and limitations and practical needs intertwine. The key questions are how many different rooms you want to monitor and what level of comfort control you are satisfied with. Pay particular attention to the trade-off between functionality, ease of use and portability of the device.

• This device is designed to simultaneously monitor temperature and humidity in multiple rooms (up to three with separate channels), which is useful for comparing conditions in an apartment, basement, or weekend home.
• Battery power allows for flexible placement, but requires periodic battery checks and replacement, which can impact long-term ease of use.
• Since the device does not include a barometer or CO₂ measurement, it is not suitable for those who expect indicative air pressure monitoring or air quality monitoring in addition to temperature and humidity.
• Automatic backlighting improves data readability in low-light conditions, but visible data is limited to basic measurements without advanced analytics or connectivity.

In practice

🟢 Monitoring temperature and humidity in multiple rooms

Very convenient – the device is designed to simultaneously measure and display temperature and humidity in up to three rooms, allowing for quick insight into conditions in different locations.

🟡 Overview of basic conditions in the room without additional data

Suitable with limitations - the device is suitable for basic comfort monitoring, but it does not allow for measuring air pressure or weather changes and is not suitable for those who want a broader overview.

🟡 Use in different places with multiple movements

Suitable with limitations – battery power allows for mobility, but with repeated movements, it is necessary to check the battery status more often and reset the connection channel.

🔴 Air quality monitoring (CO₂)

Less suitable – the device does not measure CO₂, so it is not suitable for users who want greater control over air quality and ventilation.

Answers to frequently asked questions

Is it possible to monitor conditions in three different rooms at the same time?

Yes, the device supports up to three separate channels for temperature and humidity measurement, so you can monitor conditions in multiple rooms at once.

What does automatic backlighting mean?

The backlight automatically turns on when lighting conditions deteriorate, making it easier to read the data display even in the dark or twilight.

How often do I need to change the batteries with regular use?

The frequency of battery replacement depends on the intensity of use, but with repeated movement or active lighting, the batteries usually last slightly less time.

Is the connection between the unit and the sensors stable in larger apartments?

Connection stability is adequate in average apartments, but poorer response or signal interference is possible over longer distances or with more obstacles.
