Keep the temperature sensing point against a stationary metal surface with an Anritsu MG Series magnetic surface temperature probe. The built-in magnet holds the head against a suitable target, helping operators take readings without continuously pressing a handheld probe into place.

For equipment surfaces, moulds and other magnetically receptive components, select the head size around the available contact area. Confirm the temperature, surface condition and cable arrangement before choosing the complete model.

MG-12 and MG-14 replacement information

MG-12 and MG-14 production ended in January 2019, with maintenance support ending in March 2020. Anritsu identifies MG-62 and MG-64 as the successor models.

Previous modelReplacement modelSelection note
MG-12E MG-62E Confirm cable, connector and installation fit.
MG-12K MG-62K Confirm cable, connector and installation fit.
MG-14E MG-64E Confirm the required grip and complete configuration.
MG-14K MG-64K Confirm the required grip and complete configuration.

The older model list on this page included MG-11K, MG-12K, MG-21K and MG-22K. MG-12K is retained here for replacement identification; it should not be ordered as a current production model.

For a custom probe based on MG-12 or MG-14, send the complete identification code and photographs. Confirm the replacement configuration before assuming dimensional or electrical interchangeability.

Surface temperature tolerance

Surface temperatureModels rated to 250°CModels rated to 400°C
-50 to 100°C ±2.5°C ±2.5°C
Above 100 to 200°C ±3.1°C ±3.1°C
Above 200 to 250°C ±4.0°C ±5.0°C
Above 250 to 300°C Outside range ±5.0°C
Above 300 to 400°C Outside range ±7.2°C

Published tolerance applies to stationary, flat and smooth metal surfaces. The nominal response is two seconds to 99% response under the manufacturer’s surface test conditions.

The durability classification exceeds 50,000 contacts under specified test conditions. It is not a guarantee of service life on every surface.

Cable and instrument compatibility

Match Type E or Type K to the thermometer or data logger input. Confirm whether the instrument requires an ANP miniature plug, ASP standard plug or another termination.

The sensing-head rating does not apply to the whole cable. Standard cable references include TS for MG-11, MG-13, MG-21 and MG-23; GW for MG-22, MG-24, MG-62 and MG-64; TA for MG-33; and GX for MG-34.

For MG-33, the TA cable has relatively high resistance. Confirm compatibility with the instrument’s permitted source resistance, particularly when specifying a longer cable.

Check the measurement surface

Magnetic attachment: Confirm that the actual target material attracts the probe securely. Aluminium, copper and some stainless steels will not provide suitable magnetic retention.

Surface contact: Paint, scale, roughness and curvature can affect both contact and readings. Describe the surface condition when selecting the head.

Cable routing: Leave sufficient slack so the cable does not pull the sensing head away from the target.

Stationary use: For moving or rotating targets, compare the Anritsu U and UX surface temperature probes.
