REED Instruments LM-8000 6-in-1 Multi-Function Environmental Meter (Air velocity/temperature, Ambient Temperature, Humidity, Contact Temperature and Light)

Description

Product Overview

The REED LM8000 is a versatile 6‑in‑1 environmental meter designed for professionals who require precise, real‑time data across multiple parameters. Housed in a rugged ABS polymer shell that meets IP54 standards, the device resists dust and splashes while remaining lightweight at just 8.8 ounces. Its pocket‑size form factor—measuring 4 x 9.75 x 2.25 inches—allows one‑handed operation, making it ideal for on‑site measurements where mobility is essential. Powered by three AAA batteries (included), the LM8000 offers up to 200 hours of continuous use, ensuring that you can rely on it throughout a full workday without interruption.

Core capabilities include air velocity measurement in meters per second, feet per minute, kilometers per hour, miles per hour, or knots, as well as temperature sensing for both ambient and contact applications. Relative humidity is displayed as a percentage, while light intensity is reported in foot‑candles or lux. The device also features Data Hold, Max/Min tracking, and an automatic backlight that activates in low‑light environments, providing clear visibility of readings at any time of day.

Usage

Designed for a broad range of industries, the LM8000 excels in HVAC system commissioning, indoor air quality assessments, and environmental monitoring in manufacturing facilities. HVAC technicians can quickly verify duct airflow, temperature gradients, and humidity levels to ensure system efficiency and compliance with ASHRAE standards. Indoor air quality inspectors benefit from the ability to capture simultaneous measurements of air velocity and light levels, facilitating comprehensive reports for building certifications such as LEED.

Field engineers working on construction sites or in remote locations will appreciate the device’s durability and ease of use. The included wrist strap allows the meter to be securely worn, freeing both hands for other tasks. Its intuitive interface—featuring a single button for mode selection and a clear LCD display—reduces training time and minimizes the risk of operator error. Whether you are calibrating ventilation fans, troubleshooting temperature differentials, or documenting environmental conditions for regulatory compliance, the LM8000 provides reliable data that supports informed decision‑making.

FAQ

What types of batteries does the LM8000 use and how long do they last?

The meter uses three standard AAA batteries, which are included in the package. Under typical usage—continuous measurement with occasional data hold—the batteries provide up to 200 hours of operation before replacement is required.

Can the LM8000 measure both dry and wet bulb temperature?

Yes. The device offers separate ambient temperature and contact temperature modes, allowing you to measure dry‑bulb temperature directly and use a wet‑bulb probe for wet‑bulb readings when needed.

Is the LM8000 suitable for outdoor use?

While the meter is rated IP54 for dust and splash resistance, it is intended primarily for indoor or sheltered outdoor environments. For harsh weather conditions, additional protective housing is recommended.

How does the light measurement function work?

The built‑in photodiode sensor detects illumination levels and displays the result in foot‑candles or lux, depending on the selected unit. This feature is useful for verifying lighting conditions in workspaces, laboratories, or clean rooms.

What is the accuracy of the air velocity measurement?

Air velocity is accurate to ±0.1 m/s (or the equivalent in other units) when the sensor is positioned correctly in the airflow stream. Calibration checks are recommended annually to maintain this level of precision.
