Expensive equipment is often utilized well below its full capabilities due to lack of proper maintenance of sensors. With Hanna solutions, this is no longer a problem. All solutions are prepared with carefully weighed chemicals of the highest grade following International Laboratory Practice guidelines. Due to the sheer volume of solutions produced, the quantity of chemicals used provides a much better resolution than if small volumes were prepared by a laboratory technician. HANNA solutions give the user the advantage of being able to perform accurate calibration at a minimal cost.
