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.
