Now you can have laboratory precision for your field turbidity measurements.
The HI 98703 Turbidity Meter is designed to provide you a simple yet accurate way to test turbidity on-site. This meter has three operating ranges; 0.00 to 9.99, 10.0 to 99.9 and 100 to 1000 FTUs that can accommodate the most turbid condition you may encounter. The HI 98703 is easy to calibrate (with 2, 3 or 4-point calibration) using AMCO-EPA standards and is ISO 7027 compliant.
Collected data (up to 200) can be downloaded to your management system using the Windows® compatible HI 92000 software.
The HI 98703 meets the requirements of GLP (Good Laboratory Practices) protocols for last calibration data storage.

HI 98703 portable turbidity meters is supplied with 5 sample cuvets and caps, 3 calibration cuvets for turbidity, 5 tag holders with tags (HI 920005), batteries (4 pcs.), AC adapter, rugged carrying case and instruction manual.
The HI 98703 Turbidity Meter is designed to meet or exceed the criteria specified by the USEPA Method 180.1 and Standard Method 2130 B.
The light beam that passes through a sample is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables like wavelength of the incident light, particle size, shape, refractive index and color. The microprocessor of the instrument performs calculations using the signal that reaches the two detectors to display the NTU value. The optical system and measuring technique allow the compensation of lamp intensity fluctuations, minimizing the need of frequent calibration. The lower detection limit of a turbidimeter is determined by the so called “stray light”. Stray light is the light detected by the sensors that is not caused by light scattering from suspended particles. The optical system of this instrument is designed to have very low stray light, providing accurate results for low turbidity samples every time.
