TES-5321 PM2.5 Air Quality Monitor

Description

The TES-5321 PM2.5 Air Quality Monitor is a portable, real-time device that measures indoor concentrations of particulate matter (PM2.5), temperature, and humidity. It displays information on an LCD screen and includes health index detection, alarms, and a six-color LED indicator to provide a comprehensive assessment of air quality.

Key Features

Measurements: The monitor measures PM2.5 (fine particulate matter), humidity, and temperature. A related model, the TES-5321A, also measures mixed gases (VOCs).

Real-time data: The device offers direct, real-time readings of air pollution levels on its display.

Health index: It includes a 0–9 health index scale that gives an at-a-glance indication of the air quality: 0 is "very good" and 9 is "very poor".

Visual and audio alarms: When the air quality reaches a preset critical or alarm level, the device activates both a visual and an audible alarm. The six-color LED indicator corresponds to different air quality index categories.

Data memory: The monitor has a manual data memory function that allows you to store and recall up to 39 readings.

Max/Min with timestamp: It records the maximum and minimum PM2.5 values along with a timestamp for when they occurred.

Power source: The device can be powered by four 1.5V AA batteries for portability or an AC adapter.

Portability: With a compact and portable design, it weighs approximately 380 grams (13.4 oz), making it easy to move around your home or office.
