The Cole-Parmer Bimetal Thermometer, Back Connect, 4 in, 50-550°F (90590-11) is an industrial dial thermometer with a 3 in dual-scale display, 4 in stainless steel stem and 1/2 in NPT(M) back connection. It measures from 50 to 550°F (10 to 290°C) with ±1% full-scale accuracy and features NEMA 4X/IP66 protection for demanding environments.
Key Features
- Wide 50 to 550°F temperature range, with a corresponding 10 to 290°C dual scale for simultaneous Fahrenheit and Celsius readings
- ±1% full-scale accuracy, meeting ASME B40.200 B40.3 Grade A requirements
- Easy-to-read 3 in dished dial, using an anti-parallax design to improve scale readability
- 5°F and 5°C scale divisions, providing clearly defined increments across both temperature scales
- 4 in long stainless steel stem, with a 0.25 in stem diameter for industrial temperature measurement
- 1/2 in NPT(M) back connection, providing the specified threaded process connection for this configuration
- 304 stainless steel case and stem, paired with a glass window for durable industrial construction
- Hermetically sealed case, helping prevent dial fogging, moisture entry, internal corrosion and coil freeze-up
- NEMA 4X/IP66 environmental protection, supporting use in demanding industrial environments
- External reset screw, allowing the thermometer to be recalibrated when required
- Specified immersion conditions for rated accuracy, requiring 2 in stem immersion in liquids or 4 in immersion in gases
- Ambient operating range of -40 to 200°F, equivalent to -40 to 93°C
Benefits
- Allows Fahrenheit and Celsius temperatures to be read from the same dial without converting between scales.
- Improves readability from different viewing positions through the anti-parallax dished dial design.
- Helps protect the internal measuring mechanism against moisture and harsh environmental conditions through the sealed stainless steel construction.
- Supports straightforward recalibration in service using the accessible external reset adjustment.
- Combines a wide temperature range, industrial process connection and robust ingress protection in a mechanical thermometer that requires no electrical power.
