GE859B-000 Portable Digital Environmental Meter for Monitoring Temperature, RH, Noise, Illuminance, and Air Velocity

Multi-Use Environmental Meter: Digital Meter for Temperature, Humidity, Sound, Light, and Airflow — Temperature and humidity monitoring with recorded data

This instrument fits facility teams, storage operators, laboratories, and compliance users that need a practical way to capture data during building a reliable record of environmental conditions for quality, traceability, and troubleshooting. 

All-in-One Professional and Home Monitoring Solution

This multifunction environmental meter is engineered to provide precise readings for sound, light, temperature, humidity, and air flow (CFM/CMM) in a single portable device. Professionals in environmental monitoring, HVAC, plant maintenance, and indoor air quality assessment will benefit from its versatility and accuracy. Home users also appreciate its ability to evaluate living spaces for comfort, noise levels, and lighting conditions.

Sound Measurement

The sound level function allows measurement in factories, schools, offices, and residential spaces. It is ideal for checking acoustics in studios, auditoriums, and high-fidelity installations, providing a reliable assessment of noise exposure and sound quality.

Light Measurement

The light meter measures luminance in the field and is fully cosine corrected to account for the angle of light incidence. A long-life, stable silicon diode ensures accurate and consistent readings over time.

Temperature and Humidity

Using a humidity/semiconductor sensor combined with a K-type thermocouple, this meter accurately monitors environmental conditions, enabling precise assessment of indoor and outdoor environments.

CFM/CMM Thermo-Anemometer

The air flow function is suitable for plant maintenance, environmental analysis, fume hood testing, and HVAC system evaluation. It provides reliable measurements of air velocity and volume in cubic feet or cubic meters per minute.

Key Features

• Large backlit LCD display for clear readings.
• MAX, MIN, and AVG measurements include a relative time clock for reference.
• Simultaneously displays sound, light, temperature, and humidity readings.
• USB interface with USB-to-UART bridge for data transfer.
• Low battery indication and Auto Power Off (sleep mode) for extended battery life.

Complementary instruments support broader environmental monitoring and workplace safety programs

Industrial facilities often deploy  such as the Multiparameter Water Quality Meter, which provides comprehensive analysis of key water quality parameters including pH, dissolved oxygen, and conductivity for field or laboratory sampling. For targeted airborne condition assessment, the Sound Level Meter Datalogger captures acoustic data with integrated logging, ideal for compliance with noise monitoring requirements in production environments. In applications requiring combined environmental and process measurements, the Portable pH/EC/TDS/Temperature Meter offers multiparameter analysis in a compact format suitable for routine quality checks where water chemistry intersects with environmental conditions.

Technical Q&A

Can this meter be used for HVAC system testing?

Yes, its CFM/CMM thermo-anemometer function is ideal for measuring air flow and evaluating HVAC performance.

Is it suitable for both professional and home use?

Absolutely. It provides accurate environmental readings for workplaces, laboratories, and residential areas.

What type of sensor is used for light measurement?

The meter uses a stable, long-life silicon diode, fully cosine corrected to account for the angle of light incidence.

Does it record maximum and minimum values?

Yes, the device tracks MAX, MIN, and AVG readings with a relative time clock for measurement reference.

Application Q&A

When is data logging especially valuable?

Logging is valuable when trends matter more than a single spot reading, such as curing history, storage conditions, verification records, or alarm-driven incident response.

Who is this best suited for?

Facility teams, storage operators, laboratories, and compliance users will get the most value when they need repeatable measurements plus a record they can review, export, or act on later.

Because it combines Type K Temp: Range: -200°C to 1372°C(-328°F to 2501°F), Air Temp: Range: -30°C~100°C(-22°F~199°F), Humidity: Range: 0~100%RH, this product is a strong fit for temperature and humidity monitoring with recorded data where documentation and repeatability are important.
