Description
ZI01 is a high-performance PID sensor module, which adopts PID sensor and high-performance microprocessor. The target gas is bombarded with ultraviolet light generated by an ion lamp. Then gas is illuminated by the ultraviolet light produced by ion lamp, which will be ionized after absorbing enough ultraviolet light energy. Concentration of the target gas can be detected by measuring the tiny current generated by gas ionization.
The module can accurately measure the concentration of a variety of volatile organic compounds (VOCs) in the environment. It has digital output and analog voltage output, which is convenient for users to use and debug, and greatly reduces the design and development cycle for users. It perfectly combines PID sensor and circuit to meet the needs of customers for field detection.
Application
It is widely applicable to portable and fixed gas detectors, as well as various occasions and equipment requiring VOC gas detection.
- Emergency response
- Industrial hygiene
- Personnel safety
- VOCs detection
- Environmental quality monitoring
- Oil and petrochemical safety
- Soil pollution and treatment
Features
- High sensitivity and resolution;
- Small sizes;
- UART and analog voltage signal output mode;
- High stability;
- Strong anti-interference ability.

Technical Support:
Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
