Industrial Thermometer
V-Shaped Die-Cast Housing: The thermometer is encased in a gold-anodized or painted aluminum "V" frame, providing superior mechanical protection and a wide viewing angle.
Shock-Resistant Glass Insert: The internal glass thermometer is cushioned with high-temperature silicone or spring-mounting to prevent breakage from industrial vibrations or thermal expansion.

Quick Answer: An industrial thermometer is a robust thermometer built to be fitted permanently to pipes, tanks, boilers and machines, commonly with a glass measuring element protected by a metal case and a stem that sits in a pocket or thermowell. The form, range and stem length of this model are confirmed on request.
Built to Stay on the Plant
A laboratory thermometer is dipped into a sample and put away. An industrial thermometer stays in place for years on a water line, oil tank or heat exchanger, where it can be bumped, vibrated and splashed. The common design protects a glass capillary inside a metal case with a window, often V-shaped in section so the scale can be read from the side, and extends the bulb into a metal stem. Other industrial designs use a bimetal coil or a gas-filled system driving a dial.
The stem is not pushed straight into the process fluid. It goes into a thermowell, a closed metal tube welded or screwed into the pipe or tank, so the thermometer can be removed without draining the system. Filling the gap between stem and well with a heat-transfer fluid or paste speeds up the response. Stems come straight or angled so the scale faces the reader, and in different lengths to reach the centre of the flow.
In teaching, thermometers of this kind appear on heat exchanger rigs, refrigeration and air-conditioning trainers, boiler models and fluid mechanics benches in engineering colleges and ITIs, where students read inlet and outlet temperatures. Tell LabEquip the range, stem length and whether you need a straight or angled pattern. A Sika-type industrial thermometer is also listed.

Applications
- Reading inlet and outlet temperatures on heat exchanger training rigs
- Monitoring boiler feed water, hot water and cooling water lines
- Temperature points on refrigeration and air-conditioning trainers
- Oil and hydraulic line temperatures on machines
Care & Handling
- Always fit the stem into a thermowell rather than directly into the process fluid.
- Fill the well with a heat-transfer fluid or paste for quicker, more accurate readings.
- Check the case window for cracks and the scale for fading at routine inspections.
- Remove the thermometer before pressure testing or steam cleaning if these exceed its range.
Why Choose LabEquip
Engineering colleges, ITIs, maintenance departments and small process plants buy these thermometers to fit trainers, rigs and utility lines. LabEquip lists this item in its General Lab Products range beside the brine thermometers used in refrigeration; contact LabEquip with range, stem length and pattern.
Frequently Asked Questions
Why fit the stem into a thermowell?
The well, a sealed metal sleeve screwed or welded into the pipe or tank, takes the pressure and flow instead of the thermometer. It also means the thermometer can be pulled out for checking without draining anything.
Why are some industrial thermometers angled?
An angled stem lets the scale face the reader when the pocket is on the side or top of a pipe. Choose straight or angled according to where the thermowell is and where people stand to read it.
What stem length do I need?
Enough to put the sensing end well into the moving liquid, ideally around the middle of the pipe. A stem that stops short mostly senses the pipe wall, which runs cooler or warmer than the flow.
Why does the reading lag behind the process?
The well and any trapped air between well and stem act as insulation, so heat reaches the bulb slowly. A little heat-transfer fluid or paste in the well shortens the delay.
Can the thermometer be used on a steam line?
Only if its range and the thermowell’s pressure rating cover the steam conditions. Give the maximum temperature and pressure when enquiring so a suitable pattern can be selected.
How does it differ from a laboratory thermometer?
A laboratory thermometer is a bare glass instrument dipped into samples. An industrial thermometer is housed in a metal case with a stem, built to be fixed on equipment and read in place for long periods.
