Design Highlights

Key Engineering & Operational Advantages

Built for continuous 24/7 industrial performance, long service life, and unmatched measurement stability.

High Thermal Sensitivity

Engineered helical bimetal coils provide immediate pointer response with minimal hysteresis.

Every Angle Swivel Mount

Allows dial to be tilted and rotated 360 degrees for effortless viewing in cramped pipe layouts.

Thermowell Protection

Fabricated or barstock thermowells isolate the gauge so it can be serviced without draining lines.

Factory Calibration

Calibrated against precision thermostatic oil baths and dry block calibrators.

Questions & Answers

Frequently Asked Questions (FAQs)

Find answers to common technical queries regarding specifications, selection, calibration, and delivery.

Rigid stem thermometers are ideal when the dial can be read directly at the pipe or vessel. Capillary gauges are used when the measurement point is inaccessible, too high, vibrating violently, or hazardous, allowing the dial to be mounted safely up to 15 meters away.

A thermowell protects the temperature stem against high fluid pressure, corrosive attack, and flow velocity erosion, while permitting easy gauge removal without system shutdown.

Yes, we provide dual scale dials with Celsius as primary and Fahrenheit as secondary.
