PH-18 series disc mounted multifunctional pH controller

>PH-18 series disc mounted multifunctional pH controller product introduction: ● All use imported chips and components, and adopt a new surface mount production process to ensure stable and reliable instrument operation; ● Simultaneous display of multiple parameters: It can simultaneously display pH value, temperature value, high point alarm setting value, low point alarm setting value, whether the instrument is in high or low alarm state, and the current time. All parameters are clear at a glance. The unique 4-20 mA current output corresponds to a pH value that is reversible and can be set to any value, providing users with greater convenience. Adopting a waterproof and airtight fully sealed shell, it can be used in extremely harsh environmental conditions with a protection level of IP65. RS485 communication (optional); Unique historical curve function, able to record the current 30 day historical data and have query function. The unique design of the operation menu brings great convenience to users, and they can use it freely without reading the manual. The backlight automatically turns off after three minutes without button operation, which not only saves energy but also extends its service life; The screen contrast level is adjustable. 16: 45:23 Current time high and low alarm setting values Measurement status Main display Temperature display 6.60 PH 25.0 ℃ L: 4.00 H: 10.00 Technical parameters: ■ Measurement range: 0.00~14.00pH ■ Resolution: 0.01pH ■ Accuracy: 0.05 level ■ Stability: ≤ 0.03pH/24h; ■ pH standard solution: 4.00/7.00/0.01; 4.01/6.86/9.18 ■ Temperature compensation: 0~99.9 ℃ (pH) ■ pH correction range: zero ± 1.45 pH; slope ± 30% ■ Action control: two sets of ON/OFF relays ■ Relay hysteresis: arbitrary setting ■ Signal isolation output: 4-20mA isolation protection output ■ Working conditions: ambient temperature: 5~45 ℃ ■ Signal input impedance: ≥ 1 × 1013W ■ Current output load: allows * * * large load to be 500W ■ Ground voltage insulation: * * * small load to be 500VDC ■ Working voltage: 230VAC ± 10%, 50/60Hz ■ Protection level: Instrument protection level IP65 ■ Suitable for composite industrial pH/ORP electrodes from various manufacturers at home and abroad ■ Size: 96 × 96 × 145 mm ■ Instrument panel installation opening size 92 × 92 mm ■ Weight: 0.9 kg Application areas: sewage treatment, power generation, aquaculture, schools, pharmaceutical factories, hospitals, fermentation, chemical industry, tap water, etc.
