PM2.5 air quality measurement
The TES 5321 monitors particulate matter concentrations from 0 to 500 mg/m³. It is built for electricians and technicians who need to verify air quality on site. The handheld unit provides direct readings without additional sensors. A three-year parts and one-year labor warranty covers the instrument.
Suited for spot checks, not data logging
This meter suits professionals who require immediate PM2.5 values during inspections or maintenance work. It does not record historical trends or export measurements to external devices. Users needing continuous monitoring or automated alerts should consider other equipment.
0–500 mg/m³ detection range
The single specification that defines suitability is the measurable concentration span of 0 to 500 mg/m³. Environments exceeding this upper limit will read off-scale. Confirm that the expected particulate levels fall within this window before purchase.

Questions about this item
Does the TES 5321 monitor require a specific mounting bracket or can it sit on a flat surface?
The unit is a handheld test instrument designed to rest on a bench or be held during use; no mounting bracket is included or required.
What is the correct way to power on the 5321 and the step users often miss?
Insert the batteries observing polarity, press the power button, then allow the sensor to stabilise for a few minutes before taking a reading.
Which part of the 5321 will need replacement after extended use?
The PM2.5 sensor element degrades over time and should be replaced when readings drift or the device fails its calibration check.
