The Ermenrich Ping SM40 is a multifunctional hidden element detector, designed to offer long service life during construction, repair, and installation work. The durable housing, made of impact- and wear-resistant ABS plastic, features three scanning modes (studs, metals, and conductive wiring). The device automatically selects the optimal detection mode based on the strongest signal, quickly adjusting its settings for various tasks.

Detection Specifications

• The detector locates wooden and metal studs up to 38 mm deep.
• Detects ferrous metals up to 100 mm deep.
• Detects non-ferrous metals up to 80 mm deep.
• Detects hidden conductive wiring up to 51 mm deep.

This level of information before starting work allows for precise mapping of mechanical installations and structural elements, preventing damage during drilling and avoiding costly rework. The automatic mode selection eliminates the need for manual adjustments.

When studs are detected, the center of the detected profile is immediately displayed on the screen, enabling accurate marking on the first attempt. The detector distinguishes between ferrous and non-ferrous metals, helping the user determine the type of obstacle and choose the optimal installation method. The AC (alternating current) mode ensures safety: the device instantly displays a warning on the screen when conductive wiring is detected. The same warning appears in any structural scan mode if a power cable is nearby.

Display and Controls

The liquid crystal display provides real-time diagnostic information. Each time the device is used, automatic calibration starts, instantly adjusting sensitivity to the material and eliminating the need for manual settings, ensuring continuous accuracy throughout the work shift.

Ergonomics and Usability

The compact, non-slip design offers a comfortable grip and allows easy one-handed use, even with gloves. An audible alert helps immediate response to detected objects, remaining effective even in low light or bright sunlight. The battery level indicator notifies when it's time to replace the battery, and automatic shutdown after three minutes of inactivity saves power and extends battery life.

The device is suitable for indoor and outdoor use, operating reliably in temperatures from 0 °C to 40 °C. This combination of accuracy, durability, and ease of use makes the device an effective assistant for professional construction as well as home repairs, saving time, reducing errors, and ensuring better results.

Key Features:

• Automatic selection of the optimal detection mode for studs, metals, or wiring, all controlled with a single button.
• Detection of wooden and metal studs up to 38 mm deep for quick identification of framing elements before drilling, minimizing the risk of errors.
• Detection of ferrous metals up to 100 mm deep and non-ferrous metals up to 80 mm deep thanks to a super-sensitive sensor, providing accurate search results even when detecting through dense materials.
• Detection of live electrical wiring up to 51 mm deep to prevent damage to cables and enhance safety during work.
• Automatic cable presence warning in every operating mode to prevent electric shock.
• High-contrast liquid crystal display for easy reading in any lighting condition.
