HQ-300

 

HQ-300

Select one component from the 6 available components.

In addition to the general water quality standard parameters of pH, ORP, DO, electrical conductivity and electrical resistivity, fluoride ion concentration measurement, which is a basic parameter of semiconductor effluent treatment, can now be measured in one transmitter. * Fluoride ion is optional.

 

HQ-300 risk reduction

Enables risk reduction when a malfunction occurs.

In addition to the general water quality standard parameters of pH, ORP, DO, electrical conductivity and electrical resistivity, fluoride ion concentration measurement, which is a basic parameter of semiconductor effluent treatment, can now be measured in one transmitter. * Fluoride ion is optional.

 

HQ-300 enables optimized inventory control

Enables optimized inventory control

When multiple types of measurement item are being managed on site, a high level of cost is incurred in keeping an inventory of transmitters in case of malfunction. However, multiparameter transmitters enable you to realize cost-effective inventory control by reducing the need to keep an inventory of transmitters to the bare minimum.

 

CHQ-300 compatible with HART 7

Compatible with the latest HART comunication (protocol revision 7)

Long tags can be set up to 32 characters in length,improvng the amount of freedom you have to manage transmitter names on site.
