Built for Australian HVAC pros. This Testo Temperature Probe Kit gives licensed techs, apprentices and contractors fast, accurate temperature readings across air, liquid/paste and surface applications. It’s a bloody good time-saver—clip it in, take the reading, and crack on.

Key Features & Trade Benefits

• Three Probes in One Kit – Air, immersion/penetration & surface. Cover ambient, liquids/pastes, pipework and plate checks without swapping kits—fewer trips to the ute.
• Type K, Class 1 Thermocouples – Industry standard. Use with Testo 915i and most Type K meters—no compatibility guessing on site.
• Fast Response Tips – Rapid T₉₀ performance. Lock in stable temps faster to dial superheat/subcooling and cut call-backs.
• HVAC-Ready Ranges – Air & immersion: -50 to +400 °C; Surface: -50 to +350 °C. Plenty of headroom for discharge lines and hot plates.
• Sprung Surface Probe – Conforms to flat and non-planar surfaces. Get dependable contact on pipes and casings—no wobbly readings.
• Rugged Build – Testo quality for daily field use. She’ll be right on rooftops, plant rooms and tight ceiling spaces.
• Universal Type K Plug – Swap between Testo and other Type K instruments already in your kit.

Why This Product Matters

Picture this: you’re up on a roof in 40-degree heat chasing intermittent head pressure issues. With the surface probe confirming discharge line temps and the air probe tracking ambient, you quickly nail the actual condensing temp and sort airflow—job done, no dramas. This kit gives you the right probe for each step so you’re not mucking around.

Pro Tip

When checking superheat on R32 or R410A, log suction line surface temperature with the surface probe and ambient with the air probe while your gauges/app calculate the rest. Label your probe leads and keep a spare bead probe in the case—future you will say “fair dinkum, that saved me.”

Compatibility & System Info

• Instrument Compatibility: Works with Testo 915i Smart Probe and most meters accepting standard Type K thermocouples.
• Typical Use: R32, R410A, R134a systems—suction/discharge line temps, coil surface checks, ambient/return air.
• Trade Fit: Commissioning, diagnostics and maintenance across split, VRF, and commercial refrigeration.

Local note: From dry Sydney rooftops to humid Brisbane plant rooms, the sprung surface probe maintains solid contact for repeatable readings—too easy.

FAQs

Q: Will these probes work with my Testo 915i?
A: Yes—this kit is Type K, Class 1 and mates with the 915i handle. If you need the handle, see the Testo 915i Thermometer.

Q: What if I need hands-free pipe temp checks?
A: Add a clamp thermometer for line temps—the Testo 115i pairs perfectly.

Q: Is there a protective case?
A: Yep—the Testo Smart Case (0516 0032) keeps the 915i and probes tidy—no worries.

Q: Do I still need an IR thermometer?
A: For non-contact surface checks, consider the Testo 805i to complement this kit.
