Product details
Weiss Bimetal Dial Thermometer | 5VBM6/250 | 5″ Dial | 6″ Stem
Product Description
The 5VBM6/250 is engineered for applications where temperature must be monitored clearly from a distance. The “5VBM” designation identifies this as a 5-inch (125 mm) Dial thermometer with a Vertical (Bottom) Mount connection. This vertical orientation is perfect for installation on top of horizontal pipelines, ensuring the dial faces the operator directly in Dubai and Abu Dhabi plant rooms.
This model features a wide temperature range of 0 to 250°F (-10 to 120°C), making it exceptionally versatile for monitoring domestic hot water supply, heating water systems, and low-pressure steam. The 6-inch (150 mm) stem provides ample immersion depth to bypass standard pipe insulation and reach the heart of the fluid flow for an accurate, real-time thermal reading.
Key Features
- Massive 5″ High-Visibility Dial: The oversized display with bold, black markings allows technicians to check temperatures at a glance without having to be directly in front of the instrument.
- 6″ Industrial Stem: Specifically designed for mid-to-large diameter pipelines, ensuring deep immersion for maximum thermal accuracy.
- All-Stainless Steel Construction: Both the case and the stem are crafted from 304 Stainless Steel, providing superior resistance to the high humidity and corrosive air common in Middle Eastern coastal regions.
- Hermetically Sealed Case: Vacuum-sealed to prevent internal fogging and moisture ingress, a critical feature for maintaining clarity in humid mechanical environments.
- External Recalibration: Features an easy-to-use adjustment screw on the back of the case for simple field calibration.

Frequently Asked Questions
- Q: Is this thermometer suitable for domestic hot water systems?
- A: Yes, the 0-250°F range is ideal for DHW headers and heating water loops in commercial towers.
- Q: Why is the 5″ dial better than a 3″ dial?
- A: In large mechanical rooms with overhead piping, a 5″ dial is much easier to read from the floor level, improving safety and efficiency.
- Q: Does this require a thermowell?
- A: For pressurized piping, it must be installed in a 6″ Weiss Thermowell (typically model E6-35BS) to prevent system leaks and allow for maintenance without shutdown.
