High-Temperature Capillary Thermometers (Remote)
-- Steady & Reliable Manufacturer --
Product Overview
Our high-temperature capillary thermometers are ideal for remotely monitoring temperatures in challenging environments, such as ovens, furnaces, heat exchangers, and boilers. These instruments operate on the principle of liquid or gas expansion within a sensor bulb, transmitting the pressure change through a flexible capillary tube to an indicator gauge, allowing the display to be safely and conveniently located away from the heat source. They provide reliable temperature measurement where digital sensors might fail due to extreme heat.
Key Features
- Remote Indication via Capillary Tube.
- Robust mechanical operation, no external power required.
- Suitable for temperatures up to 600∘C.
