Accessories & Test Leads

The Test Leads & Accessories category includes the essential add-ons technicians use to expand, protect, and enhance their HVAC test meters. Leads and probes are the direct connection between your multimeter or clamp meter and the system, making accuracy and durability critical for safe electrical diagnostics.

Here you’ll find silicone test leads, needle probes, alligator clips, blade probes, magnetic hangers, thermocouples, lead extensions, and replacement lead sets. Many options are CAT-rated, high-temperature resistant, kink-free, and designed for tight HVAC panels and challenging service conditions.

• Silicone test leads with high flexibility and heat resistance.
• Alligator & crocodile clips for hands-free connections.
• Needle & piercing probes for low-voltage and control wiring.
• Blade probes for tight terminals and push-in connections.
• K-type thermocouples for temperature measurement add-ons.
• Magnetic straps & hangers for securing meters to metal panels.
• Lead extensions & replacement kits for long reach and meter upkeep.

When selecting test leads and accessories, check for CAT safety rating, insulation type (preferably silicone), needle sharpness, clip strength, probe length, and compatibility with your meter’s input jacks. High-quality leads improve both safety and reading accuracy in HVAC electrical work.

Pro tip: Always keep an extra set of silicone leads, alligator clips, and at least one K-type thermocouple in your service bag. Damaged leads are one of the most common causes of inaccurate readings or intermittent results in the field.
