Mettler Toledo 51338014 Bromonaphthalene density/refractive index combined standard (9 ml) - Certified Standard
Two Parameters in One
The combined density and refractive index standards verify both measuring cells of a combined instrument in one simple step.
No Manual Handling
The standard reference material comes in vials suitable for direct use on our SC1 and SC30 automation units – no syringe needed.
Barcode Certificates
All certificate information is coded in a single barcode. Users can simply scan the barcode and the system will do everything else.

Hanna Instruments HI-93414-02 EPA Compliant Turbidity and Free & Total Chlorine Meter
The HI-93414 is a multiparameter instrument that measures the most important parameters in drinking water: turbidity and chlorine. The instrument is based on a state-of-the-art optical system which provides accurate results by minimising stray light and colour interferences.
The colorimeter portion of the meter uses a 525nm narrow band interference filter for maintaining the proper wavelength in the measurement of free and total chlorine
