ATAGO has established a close network ofcustomers by providing excellent customer
service and support . When an ATAGO
instrument needs servicing, not only is eachcustomer treated with respect, but they arealso provided with detailed methods anduserspecific suggestions on sampling andtaking measurements, based on individualneeds.

Chemicals and medicine▲

Efficiently using an analog unit depends on
how easily the measured value can be read.
Extensive research and the use of quality
optics result in a measurement scale that is very
bright, creating a high contrast to see clearly
where the boundary intersects the memory linesof the scale.

ATAGO has developed a spoon-shaped tip that
automatically spreads the sample across theprism. This makes the instrument even moreuser-friendly. saving valuable time.
