BZ29OS Digital wireless weather station and climate monitor with outdoor sensor

9-in-1 combination device with indoor/outdoor temperature, indoor/outdoor humidity, air pressure, weather forecast, feel-good indication, frost alarm, moon phases, time/weekday/date display and digital alarm clock

More precise than any weather app: weather station with climate monitor for an active and healthier life

How will the weather develop today? Is it cold and rainy outside or are the sun and warmth tempting you outdoors? If you want to wake up well-informed in the morning and plan your day optimally, the wireless weather station with room climate monitor BZ29OS is an indispensable planning aid. Weather apps and weather news can mostly only provide rough information about the weather situation in the entire region. The BZ29OS with high-precision indoor and outdoor sensors measures the most important climate parameters directly at its place of use.

What will the day be like? The BZ29OS knows it!

Whether at work, at home or in your free time: The weather and indoor/outdoor temperatures have a significant impact on our activities. After all, no one likes to mow the lawn when it's raining, or get on a bike when a storm threatens.

Likewise, a poor room climate has a direct impact on our well-being, health and productivity. It is primarily the air temperature and humidity level that make up a healthy indoor climate. Depending on whether it is too warm, too cold, too humid or too dry, the human body reacts differently. Room air that is too dry increases our risk of catching a cold. If the air is permanently too damp and too cold, there is a risk of mould growth. For a healthy life, we therefore recommend always keeping an eye on the most important room climate parameters. A particularly stylish and simple way to do so is by using the compact wireless weather station BZ29OS – even when you are on the go. With its easily comprehensible smiley symbols, the feel-good indication tells you which range your room climate is in (dry, comfortable, humid). The compact weather station draws its operating power either from the supplied power adapter or from 1.5 V AA batteries. The radio-controlled outdoor unit is powered by two alkaline batteries.

The thermohygrometer, which can be used as a table-top or wall-mounted device, has a 7.5" LC colour display and provides all the important room climate parameters, the weather conditions outdoors, a weather forecast and a variety of other useful measurement data at a glance. The brightness of the display can be set in 3 levels (100 % / 30 % / 0 %).

All important room climate and weather data at a glance:

  • Indoor and outdoor temperature and humidity level indication
  • Indication of time, weekday, date, weather forecast, feel-good indicator and air pressure
  • Air pressure changes over the past 12 hours
  • Forecast indication for temperature, humidity level and weather
  • Simplified feel-good indication
  • Moon phase indication
  • Adjustable outdoor temperature alarm
  • Frost alarm from ≤ 1 °C
Comfort chart

The comfort chart indicates the feel-good climate range

As illustrated in this comfort chart (according to Leusden and Freymark), we feel most comfortable at temperatures between 20 and 22 °C and a relative humidity of 40 to 60 %.

Climate conditions beyond these values are perceived as unpleasant by most people. Moreover, too high humidity levels can cause the most varied types of damage. Often, the first visible warning signs are damp articles of clothing, a musty smell and stained walls (mould stains) or sprouting potatoes in basements. For example, did you know that mould can already form at 70 % humidity – and rust at just 60 %? If it is not controlled, the humidity level in a room can fluctuate significantly and rarely reaches the ideal values on its own – and it additionally also depends on the season and climatic conditions outdoors.

With the indoor climate monitoring unit you can easily keep an eye on the temperature and humidity level. 

BZ29OS – a true all-rounder

The thermohygrometer BZ29OS continuously measures the current temperature, relative humidity and air pressure as an indicator for indoor and outdoor weather forecasting. Trend changes in the values are visualised graphically, just like the threat of frost. Alarm temperature values can be set for the outdoor unit. The temperature measuring range is from -9.9 °C to +50 °C indoors and from -40 °C to +70 °C outdoors. The relative humidity is measured from 1 % RH to 99 % RH. Via the integrated MAX/MIN function the measuring device indicates the day's highest and lowest measured value. 

For a reliable weather forecast with symbolic weather trend display, there is a barometer with 12-hour bar graph display integrated. Since the air pressure is measured continuously, the BZ29OS allow for a precise weather forecast.

Is the room climate within the ideal range?

A simple glance at the measuring device reveals whether the room air is too dry or too humid. A coloured smiley symbol indicates whether the humidity level is in the optimum range. Tip: If the room air is too humid or too dry, we recommend using dehumidifiers or humidifiers to create a healthy room climate.

Smart and alert: convenient alarm mode with snooze button

The high degree of functionality and information provided by the BZ29OS is rounded off by a graphic moon phase indication, an integrated DCF radio clock with 12/24-hour display and date/weekday display as well as a battery status indication.

Furthermore, the BZ29OS comes with an integrated, convenient digital alarm clock, making it ideally suited for the bedroom as well as for the camper van or backpack when on the road. Are you having difficulties getting up in the morning? One push of the snooze button allows you to sink back into your pillow for another 8 minutes. And if the weather forecast promises a sunny day, it is much easier to rise and shine!

Always make the right decisions with the wireless weather station BZ29OS

Whether work, hobby, leisure or holiday – the weather influences our decisions every day.

The right clothes for the day

We all know these questions: will it be sunny and warm today, or rainy and cold? The first weather-dependent decision of the day is usually what to wear. Be on the safe side when choosing your wardrobe, and rely on the forecast of the wireless weather station BZ29OS.

More fun while gardening

When it comes to garden and landscape maintenance, reliable weather data is an indispensable aid. With the weather station BZ29OS you can estimate how the weather will develop in the days to come. Depending on the weather, there may be no need to water the flower bed, irrigate the garden or mow the lawn. This makes gardening more fun, the garden will be able to flourish optimally and the lawn will be protected from dehydration and burns in the summer.

Leisure and outdoor activity planning

Enjoying the wind in an open convertible is great – weather permitting. With a reliable weather forecast, the planned convertible trip won't be rained off. Outdoor activities such as kite flying, Nordic walking, climbing, cycling or running are only really fun when the weather conditions are good. Those who base their plans on the precise forecasts of the weather station BZ29OS get the most out of their free time. When used in a camper van, the wireless weather station BZ29OS impresses with its practical battery operation.
