Aster Digital PH Meter

Product Details:

pH is the measure of the hydrogen ion concentration in a liquid. pH measures the acidity or alkalinity of a liquid. The pH scale is logarithmic and runs from 0.0 to 14.0 with 7.0 being neutral. Readings less than 7.0 indicate acidic solutions, while higher readings indicate alkaline or base solutions. Chlorine and Ozone are the most common disinfectants used in the water and waste water treatment industry. Oxidation-reduction potential (ORP) is the parameter commonly used to measure REDOX reactions and is the only practical method we have to electronically monitor disinfectant effectiveness.

Features:

• Traceability to National Standards
• Push Button Front Keys for easy set up
• Individual High & Low Set Point Relay for alarm or signal to PLC or can be used for proportional acid/alkali dosing
• Programmable Control Delay Time to prevent chattering
• Hysterisis To Prevent Relay Chattering Hysterisis is the percentage of set point below/above which relay will reset after getting energized
• In-Built Diagnostics for wrong calibration or sensor error
• In-Built Alarm Annunciator It's a facility to acknowledge high/low fault condition and reset relays by pressing the acknowledge key
• Manual/Automatic relay reset options
