The Elma Laser 4 Dual is a truly unique distance meter that measures in both directions, or up and down. No more getting on your knees to measure a room height, or having to go all the way to the wall to find the width. With the Elma Laser 4 Dual, you simply measure from the middle of the room, and with its dual laser, it measures both the distance to the ceiling and floor, displaying the total room height. Or, stick your hand through the ceiling hatch and measure the entire length of the attic in one press. This saves time and ensures accurate measurements.

The laser is also equipped with a digital color display that rotates based on how the instrument is held, making readings easy from any angle. In addition to the digital display of the tilt, a digital version of the bubble level has been added, which, with its clear green color, indicates when the instrument is held horizontally.

Furthermore, the instrument features many standard functions from professional distance meters, such as tracking for continuous measurement, the Pythagorean function for indirect measurements like façade heights, etc. It also includes the +/- function and a calculator for calculating areas and volumes. It is delivered complete with a carrying case, batteries, and a  user manual.

Correct testing and verification in accordance with IEC 60364-6 can be extensive, but no less important, as installation testing is quality control and thus the foundation when it comes to the functional and personal safety of electrical installations.

The first step for correct testing and verification is a test instrument with the necessary measurement functions; the next step is that the test instrument is user-friendly, and these are the points where the Elma iTest 7400 stands out!

To make the operation of the Elma iTest 7400 as easy as possible, test functions are selected with a rotary switch while test settings are changed via arrow keys. Settings and measured values are easily read on the colour display, which can also show help images if there is any doubt about a test setup.

The Elma iTest 7400 is equipped with functions for initial verification, periodic inspection, and troubleshooting of electrical installations:

• Continuity test with 200 mA for verification of the protective conductor's continuous connection and/or potential bonding, as well as a simple continuity test/beep test with low test current.
• Insulation resistance test at predefined test voltages from 50 V to 1000 V and adjustable threshold value.
• Measurement of line impedance and voltage drop. Built-in fuse tables with thresholds make it easy to determine if the installation is safe.
• Measurement of fault loop impedance taking into account the type of residual current protection for easy verification and without tripping the RCD.
• RCD testing of all common types of residual current devices – also EVSE 6 mA DC. Separate test functions for trip time, current ramp test, and auto-test.
• Voltage, frequency, and phase sequence measurement.

The Elma iTest 7400 is delivered in a softcase including test leads, probes, crocodile clips, test cables with both DK-EDB plug and schuko plug, rechargeable batteries and charger, calibration certificate, and user manual.

Elma BM2805 is a sturdy TRMS multimeter with backlit LED display capable of measuring voltage, current, frequency, resistance, capacitance, diodes and continuity. Functions include max-hold, data-hold, auto-range, relative values and VFD filter.

Elma BM2805 warns in case of erronous connection, can be overloaded and is fitted with highly efficient fuses.

Elma BM2805 complies with IEC 61010 CAT IV 600V/CAT III 1000V, and is delivered with testleads, battery, rubber protection cover, and manual.
