Key benefits Allinone environmental tester: combines a noise meter, temperature meter, and humidity meter in a single device, simplifying field work and reducing the need for separate instruments. Realtime, easy interpretation: onscreen display shows ambient temperature, humidity, and noise values simultaneously for quick, informed decisions. Reliable and efficient performance: designed for low power consumption with stable operation to minimize maintenance and running costs. What it does Multifunctional testing: integrates noise, temperature, and humidity measurement to provide fast, comprehensive environmental data. Realtime display: digital screen presents ambient temperature, humidity, and noise values in real time on one screen, enabling ataglance assessment. Userfriendly operation: four control buttons support straightforward control and precise measurement modes in various conditions. Design and usability Handheld and portable: compact, lightweight handheld body designed for comfortable handling during field testing. Easy control: four intuitively placed buttons for smooth operation in the field or onsite. Power and endurance Builtin rechargeable battery: 1600 mA lithium battery provides long runtime between charges. TypeC charging: convenient, modern charging port for quick ups. Low power consumption, stable performance: optimized for extended use in demanding environments, helping to reduce usage costs. Specifications and attributes emphasized Functions: noise meter, temperature meter, humidity meter; realtime ambient readings on a single display. Display: digital readout showing temperature, humidity, and noise values simultaneously. Form factor: handheld, compact, lightweight design suitable for onsite use. Power: builtin 1600 mA lithium battery; TypeC charging; low energy consumption with stable performance. Controls: four control buttons for easy operation. Use scenarios Field environmental assessment: technicians can quickly evaluate site conditions (noise, temperature, and humidity) on the go without carrying multiple devices. HVAC installation and maintenance: verify that installed systems maintain target temperature and humidity levels while monitoring ambient noise in the space. Office, lab, or industrial environment checks: perform regular climate monitoring to ensure compliance with comfort or safety standards, or to troubleshoot unexpected environmental fluctuations.
