Sensor WLD, fine particles, 0 … 500 µg/m³

Wireless sensor for NAWI with display (WLD = wireless sensor with display).

Thanks to its integrated colour display, this WLD sensor is also a standalone digital measuring device. Simple measurements therefore take only a few seconds.

The display shows the following parameters:
.) Measuerment value
.) Unit of measurement
.) Connection status (mobile or PC)
.) Sensor ID
.) Battery capacity and charge status

Of course, this WLD-SMART sensor can also be used wirelessly via Bluetooth or wired via USB with the free "Science#" app on mobile devices such as tablets or iPads (Android or iOS) or computers (Windows or Mac).

A single button press is all it takes to display other measured values (only for sensors with multiple measuring ranges or multiple built-in sensor types) or to calibrate sensors.
Up to 4 sensors can be used simultaneously in BT mode.
Display: 0.96" OLED colour display (128 x 64 pixels)
Power supply: Li-poly battery (3.7 V 700 mAh)
Operating time 4 to 22 hours with a fully charged battery (depending on conditions of use)
Connection: Bluetooth 5.0 Low Energy (BLE) (Mac, Android, iOS) - and Bluetooth 2.1 Classic (Windows)
USB 2.0 (Type C)

Delivery includes USB-C cable for charging the battery, data transfer or wired measurement for a higher sampling rate.

For measuring particulate matter (10 μm) and ultra particulate matter (2.5 μm) in the air.

- Measuring whether particulate matter is produced when using a gas stove
