Surface درجة الحرارة متر
A handheld contact temperature meter with a single Type K thermocouple input and spring-band surface probe for direct checks on panels, pipes and equipment housings.
- Direct Type K contact measurement.
- Conforming spring-band surface probe.
- Hold, minimum, maximum and average recall.
مقدمة المنتج
This contact surface temperature meter reads the thermoelectric voltage from a Type K probe and applies cold-junction compensation inside the handheld instrument. Its separate surface probe uses a thin resilient thermocouple strip that conforms to a flat or gently curved workpiece with light, repeatable pressure. A backlit LCD and direct-access hold, minimum, maximum and average functions support comparison of equipment surfaces without the emissivity uncertainty associated with non-contact infrared readings. The keyed miniature connector allows the meter to accept alternative compatible probes when air, immersion or narrow-access measurements are required.
الخصائص الرئيسية
Spring-band sensing tip conforms to flat, slightly convex and mildly uneven surfaces under light pressure.
Single keyed Type K miniature input keeps polarity and probe replacement straightforward.
Backlit LCD with hold, minimum, maximum and average functions supports repeatable survey records.
Separate probe handle and flexible strain-relieved cable keep the operator's hand away from the test surface.
Protective TPE boot, rear kickstand and replaceable battery suit bench and field measurements.
مخاوف المنتج للعملاء
Reliable contact readings depend on full sensor contact, consistent pressure, probe angle, response time and local heat flow, so the probe geometry and handling method should match the surface being checked.
Tilting the probe or applying inconsistent force can leave the sensing strip partly off the surface and slow or bias the reading.Use the spring-band head square to the surface with light repeatable pressure, and hold it steady until the display stabilizes.
A cold probe, moving air or nearby radiant heat can influence the initial indicated temperature.Allow the probe to acclimate, shield the contact point from drafts where practical, and compare readings under the same operating conditions.
One probe shape cannot make reliable contact with every flat plate, small component, pipe or narrow slot.Select a flat spring-band, small-head, right-angle paddle or pipe-clamp Type K probe to match the target geometry.
A contact probe can conduct heat away from a thin or low-mass surface during a long measurement.Use a low-mass fast-response contact strip, minimize dwell time after stabilization, and repeat the reading to check consistency.
