Detail Hardness, EPA Portable Photometer

The HI96735 portable photometer is for the 

measurement of total hardness. Hanna's 

portable photometers feature an advanced 

optical system; the combination of a special 

tungsten lamp, a narrow band interference 

"lter, and silicon photodetector ensure 

accurate photometric readings every time. 

The Hanna exclusive CAL Check™ feature 

utilizes ready-made, NIST traceable standards 

to verify both meter validation and calibration. 

The exclusive cuvette locking system 

ensures that the cuvette is inserted into the 

measurement cell in the same position every 

time to maintain a consistent path length.
