Voltage: 198VAC~242VAC, 50Hz ± 1Hz Power: ≤ 8VA Insulation: Power supply to ground 1500V/1 Minute no arcing alarm output: dual normally open programmable relay contacts: 5A/30VDC or 5A250VAC. Communication: CAN bus (optional) Storage and transportation temperature: -25 ℃~55 ℃ (excluding electrodes, electrodes should be higher than 0 ℃) External dimensions: 158 width x 158 height x 170 depth mm Hole size: 140mm x 140mm Weight: 2 kilograms --------------------------------------------------------------------------------------------------------------------------------------------------The electrode structure is sturdy and has strong anti pollution ability. Two relays can achieve high/low temperature or oxygen concentration alarm. Two channels of 4-20mA are available Isolation current output ◇ has data storage function, which can store measurement data for at least one month -------------------------------------------------------------------------------------------------------------------------------. The display screen adopts a 192 × 64 dot matrix LCD with Chinese display. All operations and programming are completed by 8 touch sensitive film buttons located on the front panel. The programming function of the instrument is protected by a 4-digit security code and cannot be easily changed. Flexibility, reliability and low maintenance are among the benefits provided by the EXA DO402G dissolved oxygen analyzer. Designed to meet the exacting requirements of measuring dissolved oxygen in the modern industrial environment, it contains many features to ensure the best precision whatever the application.The DO402G accepts inputs from both galvanic and polaro-graphic sensors. Percent saturation, mg oxygen/l water, and ppm DO can be displayed and transmitted. Compensation for atmospheric pressure altitude, salin­ity and temperature are included for the best accuracy of measurement Conductivity meter

1. Instrument features

1. The instrument uses high-performance integrated circuits to form a stable sine wave generator, resulting in stable display and small drift;

2、 The instrument adopts a phase sensitive detector to suppress the influence of distributed capacitance from electrode leads on measurement. Therefore, this instrument does not require a capacitance compensation regulator, and can automatically compensate for gear shifting and measure low conductivity values;

3、 Synchronized switching of instrument signal so
