Description
The SUPCO EM80 is a compact, Class/Type 2 sound level meter built for HVAC techs who need fast, reliable noise readings around compressors, fans, plant rooms and rooftops. It covers 30–120 dB, shows an analogue bar for quick glance checks, and ships in a hard case — too easy.
Key Features & Trade Benefits
- 30–120 dB measuring range — covers typical plant noise from quiet AHUs to rowdy condensers; no mucking about with extra gear.
- Auto or manual range — lock a range for steady readings on fluctuating equipment, or leave it to auto when you’re moving quickly.
- Analogue bar indicator — get the trend at a glance so you can diagnose spikes without diving into menus.
- Backlit LCD + auto power-off — clear reads in dim plant rooms and longer battery life on site.
- Field-calibratable — supports on-site check with a calibrator to keep readings on the money and reduce call-backs.
- Type 2, A-weighting — aligns with common workplace checks (A-weighted, 31.5 Hz–8 kHz). Note: for formal compliance surveys, your site may specify Class 1 gear — check your procedure.
Why This Meter Matters
Picture this: you’re up on a roof in summer, unit screaming, client says “it’s louder than last week”. You pull the EM80, run a quick A-weighted check near the discharge, and confirm a 10 dB jump — likely a loose guard or failing bearing. Five minutes, problem isolated, client happy. That’s a bloody good result and fewer return trips. For more instruments, browse Environmental Testers.
Pro Tip
Doing outdoor measurements? Fit a windscreen and use Slow response with A-weighting for steadier readings. If you carry a calibrator, check at 94 dB before your first round — fair dinkum accuracy starts there.
Compatibility & System Info
- Weighting/Type: A-weighting, Type 2 field meter — suitable for indicative workplace checks and HVAC troubleshooting.
- Freq. range: ~31.5 Hz to 8 kHz typical for Type 2 SLMs in this class.
- Typical accuracy: up to ±1.5–2 dB in mid-range (under ~94 dB).
Local note: Whether you’re commissioning in Sydney high-rises or troubleshooting in humid Brisbane, the EM80’s quick auto range and backlight help you work faster — no worries.

FAQs
Is the EM80 suitable for compliance testing?
It’s a Type 2 meter, ideal for indicative site checks and HVAC troubleshooting. Many compliance surveys (under AS/NZS 1269 programs) specify Class 1 instrumentation and a documented calibration. Check your site’s WHS procedure and the Safe Work Australia Code of Practice for noise.
Which weighting and response should I use?
Start with A-weighting (human hearing) and Slow response for general checks; switch to Fast to capture spikes. For outdoor work, use a windscreen on the mic.
