The Elcometer 113 Limpet Magnetic Thermometer continuously indicates the surface temperature of steel and other magnetic materials. Surface temperature is one of the climatic conditions that decides whether a coating can be safely applied: if the steel is too hot or too cold, or too close to the dewpoint, the paint can fail to cure or condensation can form under the film, so a reliable surface reading is part of avoiding premature coating failure.
The Elcometer 113 Limpet Magnetic Thermometer works from a bimetallic strip rather than electronics, so it needs no batteries, though it does require time to settle to the surface temperature once attached. Its magnetic body holds it directly against the steel for a continuous reading during preparation and application. The Elcometer 113 Limpet Magnetic Thermometer measures 57 x 20mm and weighs 56g, making it easy to leave in place on a workpiece.
Four versions of the Elcometer 113 Limpet Magnetic Thermometer cover different temperature ranges to suit the application: G113-1 reads -40°C to 60°C, G113-2 reads 0°C to 120°C and G113-3 reads -20°C to 250°C, with the G113-2B economy model covering 0°C to 120°C at a lower cost. Used by coatings applicators and inspectors monitoring climatic conditions on structural steel, tanks and fabrication, the Elcometer 113 Limpet Magnetic Thermometer is supplied by BAMR, South Africa's authorised Elcometer distributor.
Elcometer 113 Limpet Magnetic Thermometer
The Elcometer 113 Magnetic Thermometer continuously indicates the surface temperature of steel and other magnetic material. The magnetic thermometers are based on a bimetallic strip and therefore do not require batteries but do require time to adjust to the temperature.
- Bimetallic strip design No batteries required, though time needed to adjust to temperature
- Available in multiple scale ranges Various temperature range options to suit different applications
- Economy version available Cost-effective option for budget-conscious users
When to use the Elcometer 113 Magnetic Thermometer
Reach for the 113 when you need to read the surface temperature of steel or other magnetic substrate before and during coating, and you want a gauge that simply clamps on and stays put. Because it runs on a bimetallic strip rather than batteries, it keeps indicating on long jobs, though it does need time to settle to the surface temperature.
- 1No batteries to failThe bimetallic strip needs no power source, so the gauge keeps reading on remote structures and long jobs where a flat battery would otherwise stop work.
- 2Stays on the steelIt holds magnetically to the substrate and continuously indicates surface temperature, freeing the inspector to do other checks while it monitors.
- 3Scale to match the jobSeveral scale ranges let you pick a thermometer suited to the temperatures you actually work in, and an economy version exists for tighter budgets.

Frequently asked questions
How does the Elcometer 113 attach to a steel surface?
The 113 is a magnetic thermometer that attaches directly to steel and other magnetic materials. No power supply is needed as the thermometer operates on a bimetallic strip mechanism.
What temperature ranges are available?
Four variants are offered: G113-1 covers -40 to 60 degrees C, G113-2 and G113-2B cover 0 to 120 degrees C, and G113-3 covers -20 to 250 degrees C. The G113-2B is an economy version of the 0 to 120 degrees C model.
Does the Elcometer 113 need batteries?
No. The thermometer is based on a bimetallic strip, so it requires no batteries. It does need time to stabilise and adjust to the surface temperature before reading.
Can the 113 be used on non-ferrous substrates?
No. The magnetic attachment means it is limited to steel and other magnetic materials.
