Electrostatic Field Meter – M 300

M 300 Auto-Compensating Electrostatic Field Meter

We are excited to introduce the M 300 Auto-Compensating Electrostatic Field Meter, the next evolution in electrostatic field measurement. Designed to replace our popular M 212 model, the M 300 combines our trusted and highly accurate measurement method with groundbreaking new features for enhanced ease of use and precision.

Key Features and Improvements

Advanced Display: The M 300 features a modern OLED display, a significant upgrade from the M 212’s standard LCD. This new organic light-emitting diode technology provides a crisp, high-contrast, and vibrant screen that is exceptionally easy to read. In fact, you get a clear reading from a super-wide 160° viewing angle, ensuring excellent visibility in all lighting conditions and from nearly any position, a capability a traditional LCD cannot match.

Advanced Distance Sensing: Say goodbye to the need for perfect positioning. The M 300 now incorporates an advanced Time-of-Flight (ToF) distance sensor. Consequently, this technology uses invisible, eye-safe laser pulses to precisely measure the time it takes for light to bounce back from a target. For this reason, the firmware automatically adjusts the measurement value, ensuring highly accurate readings across a dynamic range of 1mm to 200mm. This versatility marks a significant improvement over the old M 212, which was limited to a fixed 1-inch distance. Furthermore, the sensor’s performance is independent of the target’s color or ambient light.

Effortless Operation: The M 300 simplifies the measurement process from start to finish. For example, unlike the M 212 model, you do not need to perform any zeroing adjustment; the M 300 is ready to use right out of the box. This intuitive design, therefore, saves you time and reduces the potential for user error. In addition, our new Snapshot Hold feature ensures that when you move the meter away from a measured object, the last reading remains on the screen for easy access before you store it in memory.

Data Storage and Portability: The M 300 now holds up to 10 measurements in memory, allowing you to log a series of readings and review them later. It is powered by a rechargeable lithium-ion battery, and for added convenience, a modern USB-C port handles both charging and easy data transfer to your computer. This change completely eliminates the need for disposable 9-volt batteries, providing a more sustainable power source.

Trusted Core Technology: At the heart of the M 300 is a highly stable, chopper-stabilized field sensor. This advanced method uses a continuously modulated signal to eliminate the low-frequency noise and thermal drift that can affect less-advanced instruments. By rapidly sampling the electric field, the sensor provides a precise and stable measurement, which it then converts to a voltage reading, thus ensuring the high standard of accuracy you expect from our instruments.
