Main technical indicators

Measurement range:0~9999μS/cm； Divided into 0.00~20.00 μ S/cm, 0~200.0 μ S/cm, 0~2000 μ S/cm, and 0~9999 μ S/cm with automatic range switching;

Temperature compensation:Equipped with automatic temperature compensation, the compensation range is 0~100 ℃, the compensation reference is 25 ℃, and the temperature compensation element is NTC10K Ω;

Display mode:Select 58 × 42 large backlit LCD screen, 4The 0.56 "LCD displays the conductivity value, and the 3-digit 0.36" LCD displays the temperature value;

Instrument level:Level 2.0;

Electrode configuration:1.00cm^-1Plastic platinum electrode, 4 'plumber thread or sanitary chuck connection, wire length of 5 meters;

Alarm control output:This instrument can select alarm settings for conductivity or TDS values. When the measured value exceeds the upper limit set value, it provides a switch contact signal output. When it returns to the alarm lower limit value, the relay is turned off. Contact capacity: 220VAC/6A;

Current signal output:This instrument can provide standard 4-20mA isolated DC signal output, and the operating conditions of 4mA and 20mA values can be set arbitrarily according to user requirements. Output type: isolated type; Output load ≤ 750 Ω; (Active)

RS-232C serial port output:This instrument has a standard RS-232C serial port output, which can be connected to intelligent instruments with this interface, such as computers and printers (DY-301B), to achieve printing and recording of measurement data;
