Product introduction

This product is a new generation of intelligent multi parameter water quality detector independently developed by our company. It has the characteristics of Chinese and English menu operation, high stability, excellent repeatability, multi-function, etc. It can accurately measure multiple parameters in the solution.

Widely used for online monitoring of environmental protection, sewage treatment, thermal power, aquaculture, food processing, printing, metallurgy, pharmacy, fermentation, chemical industry, tap water and other environments.

main features

◇ RTOS system is adopted to enhance the performance, stability and real-time performance and better manage peripherals.

◇ Large screen dot matrix LCD display, Chinese and English menu operation, simultaneous display of multiple parameters.

◇ Automatic/manual temperature compensation, PT1000, PT100,10k, 2.252k, 22k can be selected for thermocouples.

◇ Communication function: RS-485 communication interface (partially compatible with MODBUS protocol) (optional).

◇ Factory settings and initialization of each channel can be restored (independent of each other).

◇ Watchdog function: ensure that the instrument will not crash.

◇ The measuring range and unit can be set arbitrarily according to the actual situation.

◇ The core components are from domestic and foreign mainstream brands.

◇ The protection grade is IP65, waterproof, moisture-proof and dust-proof.

Technical indicators

1. Measuring parameters: temperature, PH, ORP, conductivity, TDS, salinity, dissolved oxygen, residual chlorine, ozone, turbidity, suspended solids, sludge concentration, hardness, cation, anion, resistivity and other digital sensors.

One multi parameter instrument can combine up to 6 kinds of parameters+temperature, or one parameter can be combined with multiple channels. Select 6 parameters, 4 kinds of conventional electrodes must be randomly combined with 2 kinds of digital sensor parameters. Example combination method:

A: Temperature PH, conductivity, dissolved oxygen, residual chlorine, turbidity, suspended solids

B: Temperature PH, PH, DO, DO, turbidity

C: Temperature PH, TDS, dissolved oxygen, sludge concentration

D: Temperature PH hardness dissolved oxygen turbidity

Temperature compensation: 0-60 ℃

2. Working conditions: ambient temperature 0-60 ℃, relative humidity ≤ 90%

3. Communication mode: 4-20MA (one channel by default, two channels need to be specially customized); 3-channel RS485 (2-channel digital signal transmission, 1-channel signal acquisition (digital sensor))

4. Output load: any corresponding parameter of 2-circuit 4-20mA, load < 500 Ω

5. Alarm output: any corresponding parameter of 6 high and low points.

6. Working voltage: 220VAC 10%

7. Size: 218 × one hundred and eighty-three × 126mm

8. Installation method: wall mounted

9. Weight: 1.5Kg (excluding electrode)

10. Protection grade: IP65, waterproof, moisture-proof and dust-proof.
