Basic functions

1. The factory standard interface in both Chinese and English allows for easy switching and simple operation.

2. Automatic and manual temperature compensation can be selected to meet various user needs.

3. Two 4-20mA outputs, corresponding to PH&ORP values, using isolation technology, with strong anti-interference ability.

4. The high and low points of the two relays can be switched freely, and the hysteresis can be adjusted freely.

5. 480 * 800 IPS LCD, clear display, 10-100% brightness can be freely set.

6. Protection level IP65, suitable for outdoor use.

7. Password management function to prevent misoperation by non professionals.

Instrument technical parameters

Measurement range: PH (0-14PH) ORP (-1999-+1999 MV).

Accuracy:+0.01 pH;+1 mV.

Resolution: 0.01pH; 1mV.

Stability: ≤ 0.02 pH/24 hours; ≤ 3 mV/24 hours.

PH standard solution: 4.01-6.86-9.18, 4.00-7.00-10.00, two-point or three-point calibration.

Temperature compensation: 0-100 ℃ manual/automatic (PT1000).

Signal output: 4-20mA isolated protection output, independently corresponding to PH&ORP maximum load of 300 Ω.

Alarm output: Two groups can correspond to high and low point alarms (3A/250 V AC) at will, with normally open contact relays.

Power supply: AC 220V.

Power consumption: ≤ 5W.

Environmental conditions: (1) Temperature 0-60 ℃ (2) Humidity ≤ 85% RH.

Dimensions: 144 × 144 × 115mm (height × width × depth).

Hole size: 138 × 138mm (height × width).

Protection level: IP65. The intelligent PH/ORP instrument replaces the awkward situation of multiple instrument installation boxes with one instrument.
