This device measures the temperature and humidity of the air contained in forage bales, straw, windrows and others, but can also be used in air, vegetation and granular materials (cereal). Measure the humidity of the air contained between the cereals, rather than of the cereals themselves. The device is equipped with an extremely resistant stainless steel probe with an ergonomic plastic handle and a stainless steel tip. Cannot be used in a liquid.
The Skywatch® AWS measures, displays and visually and acoustically warns the user of temperature, humidity and wind speed. The minimum and maximum values of temperature and humidity are individually adjustable. The wind speed can be measured on 2 levels. The display box, independent of the sensors, provides a wide variety of applications.
This porosimeter was developed and manufactured by JDC Electronic SA following a very strong demand from paragliding manufacturers, mainly for safety reasons. This instrument quickly became the leader in the field of porosity. It is now used and appreciated all over the world.
The SalinoMADD equipment is intended for hydrology professionals who often perform flow gaugings, sometimes in difficult conditions. It can record up to 15 measurement sites with a wide variety of additional information.
Perfectly waterproof, it is equipped with a conductivity probe with a 10m cable and a screw connector. It comes in a very robust case and is accompanied by all the equipment necessary for its calibration: test tube and calibration doses.
This instrument gives you precise instantaneous speed on the water, the maximum speed, as well as the distance travelled on the water. And all this without having to make any changes to your boat. Easy to install: attach the propeller underwater with one of the three fins included; place the radio transmitter in the hull. Magnetic transmission through the hull without hole (JDC patent) and radio transmission on the screen (up to four metres). You have the option to fix the screen anywhere on the boat, which allows the transmission of data to everyone with a receiver. Ability to use existing detector paddles. Calibration possible for interaction with any type of speed controller (JDC propeller or paddle sensor).
Skywatch® Windoo products are weather stations for your smartphone. They measure and transmit the following types of data: wind speed, temperature, perceived temperature, humidity, dew point and pressure.

Skywatch AEROlog Software
The SKYWATCH AEROlog software allows complete control of the station, including the reading and the export of the data, the programming of the intervals of measurements or the choice of the units of display. Real-time measurements as well as recorded data can be viewed graphically.
