Horiba U-50 Series Instruction Manual pdf
Horibas U-50 series is a line of water quality meters that allows you to measure up to 11 parameters at the same time. It is designed to be both rugged and easy to operate making it a perfect match for field work. Sampling rivers, environmental groundwarwe wells, lakes, runoff and drainage is right up this meters alley. See the chart below to help decide which model fits your needs.
The Horiba U50 series replaces the discontinued u-10 line of multiparameter water quality meters. The ruggedness and universality of the line allows for years of field use with minimal repair. Order with a 30 meter long cable for down well use or the 2 meter cable for use at the surface as you collect groundwater samples from your monitoring wells. Count on Horiba for quality and dependability.
