Features:

• Easy measurement: just mix the reagent in the sample, gently shake, insert the cuvette, zero the meter, and then press read.
• Built-in timer: Ensures appropriate reaction time is used for the chemical reaction.  At the end of the timer, the meter will automatically take the reading ensuring consistency across multiple users.
• Built-in indexing indent: on the meter which allows for a lock and key fit with the cuvette cap.  This ensures that the cuvette is indexed consistently (same position) in order to maintain the same path length for accurate results.
• Built-in error messaging display:  This helps the user ensure no mistakes are made in the testing process.  Messages include no cap, over range and under range, light source errors, and zero cal error.   
• Zero-point calibration:  Simply insert the unreacted sample cuvette into the chamber, index the cuvette, and press the zero button.
