Modbus Water Quality Transmitter 2 Alarm Relays Peracetic Acid Analyzer
2 Alarm Relays Peracetic Acid Analyzer Standard Modbus For Industrial Cooling Water
Product Introduction
Peracetic acid (C2H4O3) is a bright, colorless liquid that has a piercing odor and a low pH value. Peracetic acid is produced by a reaction between hydrogen peroxide and acetic acid. The DRFN’s peracetic acid analyzer ADS2-U3-P9.2 offers ease of use, accuracy and reliability for the monitoring and control of peracetic acid in water. The PAA analyzer consists of a transmitter and a peracetic acid probe.
Features Of The Transmitter
>> The peracetic acid controller is equipped with 2 settable 0/4~20mA active current loop outputs;
>> The standard configuration of the PAA transmitter is 2 settable SPST alarm relays;
>> Time and historical data recording functions to meet the user’s higher data management requirements;
>> Provide 100~240V AC or 18~36V DC power supply mode, both of which are wide-voltage power supply;
>> The communication standard is equipped with a two-wire RS485 interface, the communication protocol is MODBUS RTU;
