The HI 83214 multi-parameter photometer is a compact instrument featuring different ranges and methods, suitable for a wide range of applications.
HI 83214 is designed and built to perform COD analysis in accordance with EPA 410.4 and ISO 15705:2002 standards.
Ensuring accurate and repeatable results, it is the ideal tool for documenting waste treatment processes.
Besides the fundamental parameter of COD, HI 83214 also measures total ammonia nitrogen and total reactive phosphorus.
The instrument can be connected to a PC through an RS232 serial port and stored measurements can be downloaded using HANNA®' HI 92000 software.
HI 83214, allows a complete wastewater analysis in a single powerful instrument.
