HTC IRX-66 Dual Contact & Infrared Thermometer – Precision Meets Versatility
The HTC IRX-66 sets a new standard for temperature measurement by combining two powerful technologies in one rugged, ergonomic instrument. Whether you’re performing rapid, non-contact scans with infrared precision or capturing point-to-point readings with a Type K thermocouple probe, the IRX-66 is engineered to deliver both speed and accuracy where you need it most.
Dual-Mode Temperature Capability
Infrared Mode (IR):
-
Wide detection range: –50 °C to 1550 °C (–58 °F to 2822 °F)
-
Ultra-fast response: under 250 milliseconds
-
Excellent resolution: 0.1 °C/°F
-
Accuracy up to 500 °C: ±1.5% of reading ±2 °C; beyond 500 °C: ±2.0% of reading ±2 °C
Ideal for fast, non-contact surface checking in environments from deep freezers to industrial furnaces.
Type K Contact Mode (TK):
-
Extensive coverage: –50 °C to 1370 °C (–58 °F to 2498 °F)
-
High accuracy: ±1.5% of reading ±1 °C (±1.8 °F)
This mode enables precise internal or surface measurements when direct contact is necessary.
Intelligent Targeting with Dual Lasers
Featuring a 30:1 distance-to-spot ratio, the IRX-66 allows focused measurement of small surface areas from a safe distance—perfect for hard-to-reach or hot surfaces like motor casings or electrical contacts. The dual circular laser pointers provide enhanced aiming precision, making the target crystal clear even in low-light conditions.
Adaptable and Accurate Across Surfaces
Thermal emissivity varies by material, which affects infrared accuracy. The IRX-66 offers adjustable emissivity from 0.10 to 1.00, enabling calibration for different surfaces such as metals, plastics, glass, or painted finishes. This ensures consistent and reliable readings, regardless of the material being tested.
Smart, User-Friendly Design & Functionality
Designed for professionals, the IRX-66 includes features addressing efficiency, safety, and convenience:
-
Switch easily between °C and °F.
-
Data Hold locks readings on-screen for documentation.
-
Max / Min / Difference / Average record modes allow deeper insight during monitoring.
-
Trigger Lock enables continuous measurements without holding the trigger.
-
High/Low Alarm settings offer visual alerts for out-of-range temperatures.
-
Auto Power-Off preserves battery life via inactivity monitoring.
-
A bright, color LCD with backlight ensures display clarity in all conditions.
-
Built-in Over-Range indication protects both device and user from mismeasurement.
Durable and Ready for Field Use
Constructed for real-world operation, the IRX-66 delivers consistent performance:
-
Powered by a single 9V battery, offering long-lasting field operation.
-
Compact dimensions (192 × 83 × 95 mm) and lightweight design (~275 g) make it highly portable.
-
Built-in soft carrying case, user manual, TP-01 temperature probe, and hook equip you from day one.
