Supported Applications
The Omega RLC-50 series consists of reversible, multi-temperature liquid crystal strips designed as self-adhesive temperature indicators. These non-toxic and electrically non-conductive labels are used in heating and cooling applications to monitor surface temperatures. The product overview identifies specific uses for monitoring electronic parts, transformers, relays, and motors.
Operating Conditions & Performance
The RLC-50 series functions as a liquid crystal temperature indicator with an accuracy of ±2°C (3.6°F). Response time is documented as fast—½ to 2 seconds typical. The strips are reversible, returning to their original state for repeated use across the following measurement ranges:
- -30 to 0°C (-22 to 32°F)
- 0 to 30°C (32 to 86°F)
- 30 to 60°C (86 to 140°F)
- 60 to 90°C (140 to 194°F)
- 30 to 90°C (86 to 194°F)
- 90 to 120°C (194 to 248°F)
Storage temperature is specified as 10 to 38°C (50 to 100°F). Users are advised that color variances may occur when interpreting liquid crystal labels and should avoid prolonged exposure to sunlight and ultraviolet light.
Configuration Options
The series is available in multiple temperature ranges, each displaying seven discrete temperature points. The model number format follows the pattern RLC-50-<TEMP_RANGE>-<PACKAGE_SIZE>. Package sizes are offered as 10 or 30 units per package (indicated by suffixes -10 or -30). Physical dimensions for each strip are 0.01 H x 0.5 W x 1.75" L.
Temperature readings are interpreted via a color-coded bar system:
- GREEN: Bar is the actual reading
- BROWN: Bar is just above the actual reading
- BLUE: Bar is just below the actual reading
The strips feature clear, easy-to-read scales in both °C and °F.
Key Product Differences
Variants within the RLC-50 series are distinguished by their specific temperature range coverage. The available ranges include low-temperature options starting at -30°C (-22°F) up to high-temperature models reaching 120°C (248°F). Specific model examples from the specification table include:
- RLC-50-30/0: Covers °C -30 through 0 and °F -22 through 32
- RLC-50-0/30: Covers °C 0 through 30 and °F 32 through 86
- RLC-50-30/60: Covers °C 30 through 60 and °F 86 through 140
- RLC-50-60/90: Covers °C 60 through 90 and °F 140 through 194
- RLC-50-30/90: Covers discrete points from °C 30 to 90 (86 to 194°F)
- RLC-50-90/120: Covers °C 90 through 120 and °F 194 through 248

Perfect temperature range for my applications.
I recently purchased the RLC-50-30/90 reversible temperature indicators. This product has a wide temperature range. We are testing heatsinks for led lamps and found our laser temp gun to be off a lot on all but black anodized heatsinks. These reusable indicators allow us to try multiple led/heatsink combinations and find the right heatsink quickly. We can tell exactly how long it takes a fixture to heat up and also how quickly it dissipates heat.

Larger label option would be nice
I have used these labels for years and found them to be very useful for reliability programs. For my current need it would be nice to have an option for a larger label that could be read from further away.
