Cartridges

Kunak AIR stations are sensor-based devices equipped with slots to insert Smart gas cartridges.

Kunak Smart Cartridges solve many of the known issues of sensor technology: sensor variability, factory and field calibration, automatic data invalidation, sensor replacement, network operation and maintenance work.

Kunak’s Smart Gas Cartridges ensure measurement control throughout the life cycle of each sensor, making the Kunak AIR stations more sustainable and our customers’ life easier.

Traceable
QC & QA

Each cartridge is calibrated and validated individually in the lab against traceable reference standards.

Endless
combinations

Combine the parameters freely. Reuse and scale your base stations at your own pace.

Plug &
Play

Simply take the old one out and replace it easily with the new one, on the field. Be back online in 2′.

More
sustainable

The electronic and mechanical parts can be
reused, making it the most sustainable AQ sensor-based station in the market.

GasPlug ^TM technology (patented)

All the cartridges have the same size and fit in any of the available sockets. Inside the cartridge, we install the sensor into a PCB that stores all its information: type, age and factory calibration. When you plug in the new cartridge, the base station just reads the information, configures itself and starts working.

Probes

Sound Level Meter

Low-cost wireless system for the monitoring of urban and industrial noise. Type 2 sound level meter that captures data in real-time and sends it wirelessly to Kunak Cloud. It monitors the noise level in critical points of different areas, provides data 24/7 and allows the configuration of alerts. Small, lightweight and easy to install.

Internal Battery

Kunak Air stations are equipped with a rechargeable lithium battery which prevents the equipment from shutting down due to a power cut. In this way, they can continue working for long periods of time until the power is restored. Different power packs are available to power the devices.

Solar panel

The 6.3-volt high-efficiency monocrystalline solar panel is robust, waterproof (IP67) and has been designed for prolonged outdoor use in any environment. The photovoltaic panel makes the device totally autonomous from the power grid, allowing the installation anywhere without civil works or in remote locations.

Indoor charger

An indoor charger with global plugs is available for testing and verification. Input voltage 100-240V AC 50-60 Hz, Output voltage 9V DC.

Outdoor charger

An outdoor charger must be used when the Kunak AIR station is going to be installed outdoors. It is small (222 x 300 x 200 mm), lightweight (220 g), waterproof (IP67) and has been designed for prolonged outdoor use in any environment. Input voltage 100-240V AC 50-60 Hz, Output voltage 12V DC (AC cable not included).

Mechanical Anemometer

It includes both wind speed and wind direction sensors. Rugged components stand up to hurricane-force winds yet are sensitive to a light breeze. It includes sealed bearings for long life.

Ultrasonic anemometer

It includes both wind speed and wind direction sensors. It is an ultrasonic self-powered anemometer. The power requirement is fairly small and is met by means of a small solar panel sitting on top of the unit along with a rechargeable lithium battery in the wider part of the stem of the unit, immediately below the ultrasonic platform.

Rain gauge

It is highly reliable, simple to maintain and simple to clean. It has proven good performance in all climates and conditions. Proven self-emptying bucket technology to ensure uninterrupted measurement of precipitation regardless of amount and intensity. It measures rain by means of a standardized orifice funnel which collects water into a self-emptying bucket mechanism.

Pyranometer

The pyranometer measures solar radiation with a high-quality blackened thermopile protected by a dome. The blackened thermopile provides a flat spectral response for the full solar spectrum range, which enables it to be used under plant canopies or lamps, when the sky is cloudy, and for reflected radiation measurements.

Wet Bulb Globe Thermometer (WBGT)

The wet-bulb globe temperature (WBGT) is a measure of the heat stress in direct sunlight, which takes into account the temperature, humidity, wind speed (wind chill) and solar radiation. It is used in OHSAS, in sporting events and by military agencies to determine appropriate exposure levels to high temperatures.

Ultraviolet-A Sensor

These UV-A sensors detect UV radiation from 300 to 400 nm and are calibrated in energy-flux density units of watts per square meter. Typical applications of UV sensors include incoming UV radiation measurement in outdoor environments or in laboratory use with artificial light sources (e.g., germicidal lamps).
