The Cole-Parmer Industrial Bimetal Thermometer, 5 in Dial, Back Connection, 12 in Stem, 0 to 250°F (90590-54) is a dual-scale mechanical thermometer for direct temperature indication from 0 to 250°F (-20 to 120°C). It combines a 5 in dial, 12 in stainless steel stem, 1/2 in NPT(M) back connection and ±1% full-scale accuracy with NEMA 4X/IP66 environmental protection.
Key Features
- Dual °F and °C scales, allowing both temperature scales to be read directly from the same dial
- 0 to 250°F (-20 to 120°C) measuring range, providing the specified temperature span for this thermometer configuration
- ±1% full-scale accuracy, specified according to ASME B40.200 (B40.3 Grade A)
- 2°F and 2°C scale divisions, providing clearly defined graduations across both temperature scales
- Large 5 in anti-parallax dished dial, designed to improve readability and reduce viewing-angle error
- All-welded 304 stainless steel construction, combining a stainless steel case and stem with a glass window
- Hermetically sealed case, helping prevent dial fogging, moisture entry, internal corrosion and coil freeze-up
- NEMA 4X and IP66 protection, supporting installation in demanding industrial environments
- 12 in stainless steel stem, with a 0.25 in diameter for the specified insertion configuration
- 1/2 in NPT(M) back connection, providing the specified threaded process connection
- External reset screw, allowing recalibration without opening the sealed case
- Defined immersion requirements, with 2 in immersion in liquids or 4 in in gases specified for rated accuracy
Benefits
- Allows Fahrenheit and Celsius temperatures to be read directly without manual conversion.
- Improves visibility during routine checks through the larger 5 in dial and anti-parallax face design.
- Supports harsh operating environments through stainless steel construction, a sealed case and NEMA 4X/IP66 protection.
- Provides mechanical temperature indication without requiring an electrical power supply.
- Supports ongoing measurement confidence through an externally accessible recalibration adjustment.
