Product Details
In-line PH meter with LCD display for environmental protection
Introduction
The In-line PH Meter with LCD Display designed for environmental
protection is a highly efficient and indispensable tool. This
advanced device is specifically crafted to safeguard our precious
water resources. Its LCD display presents pH readings in a clear,
easy-to-read format, allowing environmentalists and technicians
alike to quickly assess water quality. The high-resolution screen
can even show additional details like temperature and measurement
time. In applications such as river monitoring or wastewater
treatment plants, it provides real-time, accurate pH measurements.
With its robust construction, it can withstand harsh environmental
conditions. Its in-line nature enables continuous operation,
sending instant alerts if any abnormal pH fluctuations occur. This
meter truly plays a vital role in maintaining ecological balance
and protecting the environment.
Features
- Automatic identification of standard solution and capable for
factory reset.
- Optional with the company's host computer online acquisition
software for data acquisition and processing.
- Note book: It can store 50 PH measurement datas , users can record
measurement data as needed.
- Waterproof, dustproof, moisture-proof (IP57), high-end design look.
- Communicate function: RS-485 communication interface with
photoelectric isolation (optional), convertible RS-232. The PH
value corresponding 4-20mA current output can be arbitrarily set,
And can control 4-20 mA positive and negative. It is widely used in
automatic addition of reagent.And it also support to connect loT of
company and customize loT for customer.
- Power off protects > 10 years.
- Watchdog function: make sure the meter doesn't crash.
- High precision, high stability and preferable antijamming ability.
- Large screen LCD display, support chinese menu(switching from each
other). Multi-parameter simultaneous display.
- Automatic temperature compensation function, manual adjustment of
PH and temperature value.
