The Cole-Parmer Industrial Bimetal Thermometer, 3 in Dial, Back Connection, 9 in Stem, -40 to 50°C (90590-08) is a dual-scale industrial thermometer for direct temperature indication from -40 to 120°F (-40 to 50°C). It combines a 3 in dial, 9 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
- -40 to 120°F (-40 to 50°C) measuring range, covering the specified operating span of this thermometer variant
- ±1% full-scale accuracy, specified according to ASME B40.200 (B40.3 Grade A)
- Fine scale divisions, with 1°C and 2°F graduations for straightforward dial reading
- 3 in anti-parallax dished dial, designed to improve readability and reduce viewing-angle error
- All-welded 304 stainless steel construction, with a stainless steel case and stem plus a glass window
- Hermetically sealed case, helping prevent dial fogging, moisture entry, internal corrosion and coil freeze-up
- NEMA 4X and IP66 protection, supporting use in demanding industrial environments
- 9 in stainless steel stem, with a 0.25 in stem diameter and an overall thermometer length of 9.875 in
- 1/2 in NPT(M) back connection, providing the specified process connection for this configuration
- External reset screw, allowing recalibration without opening the sealed case
- Defined immersion requirements, with 2 in stem immersion in liquids or 4 in in gases specified for rated accuracy
Benefits
- Allows operators to read Fahrenheit and Celsius temperatures without converting between scales.
- Improves visibility and reading confidence through the large anti-parallax dial and clearly defined graduations.
- Supports demanding installations through stainless steel construction, a sealed case and NEMA 4X/IP66 protection.
- Provides a straightforward mechanical temperature indication without requiring an electrical power supply.
- Supports ongoing measurement confidence through the externally accessible recalibration adjustment.
