Product Details
KDM-110 online PH meter with strong anti-interference ability and
high precision
Introduction
The KDM-110 online PH meter is truly a standout in its class,
especially when it comes to applications demanding the utmost
accuracy and reliability. Boasting a strong anti-interference
ability, it utilizes state-of-the-art technologies like optical
coupling isolation. This shields the meter from the chaos of
electromagnetic fields and electrical noise that are prevalent in
industrial settings, ensuring uninterrupted and precise operation.
Its high precision is equally impressive. With advanced sensing
mechanisms, it can detect the minutest changes in pH values, down
to an accuracy of ±0.05pH. Whether it's in a chemical laboratory
where exact pH control is key for reactions, or in a water
treatment plant safeguarding the quality of the water supply, the
KDM-110 provides consistent, trustworthy readings. It's the go-to
choice for professionals who won't settle for anything less than
excellence in pH measurement.
Features
- 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.
- Power off protects > 10 years.
- Automatic identification of standard solution and capable for
factory reset.
- 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.
- 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.
