Product details
Weiss Industrial Thermometer | 9″ Scale | 20-120°F & °C | Dual Scale
Product Description
This Weiss Industrial Glass Thermometer features a wide-angle, easy-to-read 9-inch (225 mm) scale with a temperature range of 20-120°F (-7 to 49°C). This specific range is optimized for chilled water applications in Dubai and Abu Dhabi’s district cooling plants, where precise monitoring of supply and return temperatures is critical for energy efficiency.
The instrument is housed in a rugged, GE Valox® polyester case, which is highly resistant to impact and the intense ambient heat found in Middle Eastern mechanical rooms. The “Vari-angle” design allows the thermometer to be adjusted to any viewing position—up, down, or sideways—ensuring maximum readability regardless of pipe orientation.
Key Features
- Vari-angle Mounting: Fully adjustable head allows the scale to be rotated 360 degrees and tilted 180 degrees for easy reading in tight spaces.
- Dual Scale Readout: Displays both Fahrenheit and Celsius to meet international engineering specifications used in UAE projects.
- Accuracy & Reliability: Precision glass tube is filled with a blue spirit (non-mercury) liquid, offering $\pm$1% accuracy of the full scale.
- High-Contrast Scale: Bold black markings on a white background ensure the temperature is visible from a distance in dimly lit plant rooms.
- Standard Fitment: Designed to be used with standard 3-1/2″ or 6″ industrial thermowells (sold separately).

Frequently Asked Questions
- Q: Is this thermometer suitable for domestic hot water?
- A: This model is rated up to 120°F (49°C). For standard domestic hot water (usually 140°F+), you should use a 30-240°F range thermometer.
- Q: Can this be installed without a thermowell?
- A: No. Industrial thermometers must be installed in a Thermowell to protect the glass stem and to allow for replacement without draining the system.
- Q: Is the blue liquid as accurate as mercury?
- A: Yes. Modern blue-spirit thermometers are highly accurate and are preferred in the UAE due to safety and environmental regulations prohibiting mercury in commercial buildings.
