We attribute much of our success to the attention we pay to maintaining our high standards of surpassing our customers expectations. Excellence is our only goal, from the quality of our products to the quality of our staff, customer response and customer care.


Irrometer

The IRROMETER operates on the tensiometer principle, which is entirely different from other systems, which measures percent of moisture. The Irrometer consists of sealed water filled tube equipped with a special vacuum gauge and with a porous tip that is installed in the ground at desired root zone depths. In dry soil, water is drawn out of the instrument, reducing the water volume in the instrument, and creating a partial vacuum, which is registered on the gauge. The drier the soil, the higher the reading. An irrigation reverses this action. The vacuum created by dry soil draws water back into the instrument from the soil, which in turn results in lower gauge reading. The instrument is in effect a “dummy root” equipped with a gauge that continuously registers “how hard the roots are working”. A gauge reading of 50 indicates that the roots are extracting the same amount of moisture whether the crop is planted in sandy soil or clay soil. Due to the Irrometer’s unique principle of operation, no calibrations are necessary under normal operating conditions for different soil types.

A new ergonomic design for comfort and ease of use!

In pursuit of an “easy to use”, “easy to operate” and ergonomic architecture of new instruments, ATAGO has achieved a “palm-fitting” masterpiece as well as a unit that is high in hygienic properties. By reducing the number of unnecessary assembly parts, we have reduced the risks of a germ reproductive environment. Through our efforts to produce a hygienic instrument to be used in any industry, these units are designed to be completely washable. The new Pocket PAL series has been approved by the HACCP, and are equipped with the new ELI feature, which ensures accurate measurements – even outdoors. Requests from our customers worldwide are reflected in the development of the new PAL units.
