Insight into the "Vitality" of Air - Wanyi Technology ONETEST-520
Series, Setting a New Benchmark for Positive and negative ion
Detection!
It's not just about concentration, but more about balance.
Revealing the ultimate electrochemical code of air quality for you.
1.Product Introduction
In today's pursuit of health and quality, we focus on
PM2.5 and temperature and humidity, but we overlook the most
dynamic element in the air - air ions. The concentration and
balance of positive and negative ions are the invisible hands that
determine the "freshness" and "vitality" of the environment.
The ONETEST-520 dual-channel air ion detector from Wanyi Technology
has come into being. It is not only a detection tool, but also your
intelligent partner for decoding environmental health, optimizing
production processes, and exploring the frontiers of science. The
sensor of this instrument adopts a coaxial cylinder electrode
design, featuring stable sampling airflow, uniform ion distribution
measurement, and strong anti-interference ability. It can
accurately measure small-sized positive and negative ions existing
in nature, as well as high-concentration negative ions produced by
negative ion generators and their products. It can be equipped with
temperature, humidity and atmospheric pressure sensors, and display
the grade of air quality and the forest air ion assessment model
(FCL), which is used to more comprehensively measure the quality of
air.
This instrument is equipped with a
large-capacity rechargeable battery and a DC12V power adapter,
which can be used for long-term outdoor measurement and recording.
It is also equipped with a dedicated PC analysis software to enable
data export and analysis. It can also be optionally equipped with
the ion.onetestinc.com cloud platform and APP monitoring service
for monitoring and transmission anytime and anywhere.
Why choose "dual-channel"? Because the truth requires
separate detection!
Traditional single-ion detectors provide a vague total
amount, while ONETEST-520 can simultaneously, independently and in
real time capture the precise concentrations of positive and
negative ions. This means you can obtain:
· True ionic equilibrium state (n+/n- ratio)
The instantaneous change trend of polarity
· In-depth environmental insights far exceeding single-channel data
Product features
1.Dual-core synchronization ensures seamless data flow
Adopting independent dual acquisition channels and high-performance
condensing collectors, the measurement of positive and negative
ions does not interfere with each other, ensuring accurate data
even in complex electromagnetic environments and capturing the
truth of every ion fluctuation.
2. As firm as a rock, it can withstand harsh conditions
The one-piece formed metal casing and circuit design endow it with
outstanding electromagnetic shielding performance and physical
durability. From the laboratory to the field site, it is your most
reliable companion.
3. Intuitive interaction, at your fingertips
The high-definition color touch screen can draw the dual-channel
concentration curve in real time. The intuitive UI design makes
complex ion data clear at a glance. One-click data export
facilitates in-depth analysis and report generation.
4. Intelligent battery life, mission accomplished
It is equipped with a large-capacity lithium battery, supporting
continuous operation for up to tens of hours. Equipped with
intelligent power management, it meets your needs for long-term
monitoring and mobile work. The dual circular sensor design enables
simultaneous and independent measurement of positive and negative
ions respectively
5. Drafting units for standard formulation
It complies with the international JIS draft, national standards,
group standards and enterprise standards for measurement.
6. Measurement of multi-functional correlation indicators
It has the function of simultaneously measuring positive and
negative ions, atmospheric pressure, temperature and humidity.
7. Built-in recording and PC software, allowing data to be exported
to a computer
8. One-click measurement is simple and easy to operate. Built-in
Chinese and English operation menus;
9. The average value measurement and the maximum value measurement
are presented simultaneously.
10. RS232 output, which can be connected to PLC or wireless
transmission devices to achieve remote measurement and control.
