Fluke 80PK-22 SureGrip Immersion Temperature Probe - Durable, Accurate

Our review of the Fluke 80PK-22 SureGrip Immersion Temperature Probe finds it best suited for technicians and lab users who need a rugged, comfortable Type-K probe for liquid and gel measurements. The single biggest reason to buy is the combination of a long Inconel sensing tip and the SureGrip ergonomic handle, which together make repeated immersions easier to steady and more comfortable during long jobs. The probe's stated range and the 1 m lead make it a practical tool for on-bench work where reliability and hand feel matter.

Key Features

• Inconel probe: The 21.27 cm (8.38 in) Inconel sensing tip provides strong corrosion resistance for immersion in liquids and gels, extending probe life.
• SureGrip handle: The soft rubber over-molded handle and finger-hugging curves improve steadiness and comfort when working with slippery hands.
• Type-K thermocouple: Built as a Type-K probe, it covers a very wide temperature span suitable for many industrial and lab tasks.
• 1 m lead: The one-meter (39 in) lead gives flexible reach from meters or benchtop instruments without needing an extension.
• Improved strain relief: The more flexible strain relief reduces fatigue at the cable join, helping the probe last through regular use.

Who It's For

The Fluke 80PK-22 is aimed at professionals and serious hobbyists who need a reliable immersion probe for liquids, gels, and general temperature spot checks. Its rugged Inconel tip and ergonomic SureGrip make it a good fit for HVAC techs, lab technicians, and field service engineers who spend time handling probes in wet or messy conditions.

Those who need ultra-fast response for transient surface measurements or who require an extremely long lead beyond 1 m should consider alternate probes tailored to high-speed surface response or custom cable lengths. For general immersion tasks however, this probe balances durability and comfort well.

Pros & Cons

Pros

• Durable Inconel tip resists corrosion and stands up to repeated immersion use.
• Comfortable SureGrip handle reduces hand fatigue and improves steadiness in slippery conditions.
• Type-K thermocouple construction provides wide temperature capability and reliable accuracy for routine measurements.
• Flexible strain relief and a 1 m lead enhance durability and practical reach for bench and field use.

Cons

• Some users report the probe measures somewhat slowly compared with thin wire thermocouples designed for fastest response.
• The fixed 1 m lead may be short for some applications that require longer reach without extensions.
