Description
Fieldpiece SNCV1 is a pocket-size, non-contact voltage detector that lets sparkies and HVAC techs quickly confirm if a line’s live from 24 VAC to 440 VAC—perfect for thermostats, control boards and service panels. It’s fast, intuitive, and built for the van. No dramas on site.
Key Features & Trade Benefits
- 24–440 VAC range — covers thermostats up to mains circuits; one stick for most jobs.
- Analog-feel response — LED & buzzer intensity increases as you move closer, giving a “read the room” feel for quicker fault-finding.
- Clear visual & audio alerts — bright red LED and buzzer help in noisy plant rooms and roof spaces.
- Pocket clip, lightweight body — clips to the shirt; always handy for quick checks between callouts.
- Non-contact safety — reduces accidental shocks when verifying energised conductors (use a meter to prove de-energised before touching).
Why This Product Matters
On a sticky summer arvo when a split won’t start, the SNCV1 lets you whip the cover off, sweep the leads, and confirm the stat’s sending 24 V in seconds. One Brisbane tech told us they keep two in the shirt pocket—if one goes missing, the job still rolls on. It’s a bloody ripper for fast triage that cuts down head-scratching and call-backs.

Pro Tip
Use the SNCV1 as a first-pass check only. Before you touch conductors or sign off isolation, verify absence of voltage with a proper meter. She’ll be right when you double-check.
Compatibility & System Info
- Detects AC voltage only (no DC) in the 24–440 VAC range.
- Ideal for HVAC/R controls, thermostats, contactors, terminal strips and general electrical quick-checks.
Local Jobsite Context (AU)
From tight ceiling spaces in Sydney apartments to rooftop plant in Brisbane, the pocket form factor keeps you moving. Quick sweep, clear indication, too easy.

FAQs
Will it pick up 24 VAC at a thermostat?
Yes — the SNCV1 is designed to detect low-voltage HVAC control circuits as well as mains up to 440 VAC.
Can I rely on this to prove a circuit is dead?
No. Use the SNCV1 for a fast presence/absence indication. Always verify de-energised status with a multimeter or clamp meter before touching conductors.
Does it work on DC?
No — it’s an AC non-contact detector. Use a suitable meter for DC circuits.
