Product details
Weiss Industrial Thermowell | ER6-75SS | 7.5″ Length | 304 Stainless Steel
Product Description
The ER6-75SS is a precision-engineered protective housing that allows for the safe removal of thermometers without draining the system. The “ER” designation identifies this as a Reduced Tip (External) design, which minimizes thermal mass at the sensing point for a faster temperature response. The “6” typically denotes a 3/4″ NPT process connection, while the “75” indicates an overall length of 7.5 inches (190 mm), and “SS” signifies the 304 Stainless Steel construction.
In the UAE’s mechanical sector, 304 Stainless Steel provides excellent resistance to oxidation and corrosion for standard water and HVAC applications. This 7.5-inch model is perfectly sized to house 6-inch (150 mm) stem thermometers, providing a 1.5-inch extension that serves as a lagging depth to clear pipe insulation in Dubai and Abu Dhabi projects.
Key Features
- 304 Stainless Steel Construction: Offers a robust and cost-effective solution for corrosion resistance in non-saline, freshwater, and standard HVAC applications.
- Reduced Tip for Fast Response: The tapered end reduces the amount of metal around the thermometer bulb, allowing for quicker heat transfer and more real-time readings.
- 5″ Total Length: Designed to accommodate a 6-inch stem thermometer, ensuring the sensing bulb is fully immersed in the fluid stream while the dial clears the insulation.
- Heavy-Duty Process Connection: Features a 3/4″ NPT external thread for a secure, leak-proof installation into standard pipe fittings.
- Maintenance Friendly: Protects the instrument from high-velocity flow and pressure, allowing for easy sensor replacement without system downtime.

Frequently Asked Questions
- Q: When should I use 304 SS instead of 316 SS?
- A: 304 SS is ideal for standard freshwater and indoor HVAC systems. If the system handles aggressive chemicals, treated seawater, or is located outdoors in highly saline coastal areas, 316 SS (like the ESS series) is recommended.
- Q: Which thermometer fits this well?
- A: This well is designed for any industrial thermometer with a 6-inch stem, such as the Weiss A9VU6 or 9VBM6 series.
- Q: Does this well protect against vibration?
- A: Yes, the rigid stainless steel construction protects the thermometer stem from bending or vibrating due to high-velocity fluid flow (Wake Frequency protection).
