Handheld VOC detectors are primarily used to measure VOC concentrations in workshops, at plant boundaries, and in emissions from stationary pollution sources, as well as for emergency monitoring during safety incidents and rapid testing to verify compliance with exhaust emission standards.
They are used in the petroleum, petrochemical, metallurgical, chemical, firefighting, natural gas, environmental protection, power, telecommunications, papermaking, printing and dyeing, wastewater treatment, food and brewing, scientific research, education, and national defense sectors.
Equipped with genuine imported PID sensors for high accuracy, the instrument features a built-in filtration system that efficiently removes impurities such as oil, water, and dust, ensuring reliable test results even in the harshest industrial environments.
User-friendly design ensures easy operation. Features a 3.5-inch high-definition color screen; testing begins immediately upon startup. A dedicated hardware power button minimizes power consumption. Includes a long-handled suction probe and an optional shoulder bag for convenient portability.
Simultaneously displays data and concentration curves. Equipped with an adjustable-speed air pump, it supports simultaneous detection of up to four gases.
An external Bluetooth printer is available as an option for on-the-go printing of test data; various wireless communication methods, such as Bluetooth and Zigbee, are also available.
Supports seamless switching between multiple gas display units, with concentration values automatically converted by the system.
Capable of gas detection in high-temperature, high-humidity, and high-dust environments (requires a sampling probe).
Display can be freely switched between Chinese and English.
Large-capacity rapid storage function; storage space is customizable.
Micro-USB charger for convenient charging anytime.
Universal Android phone data cable for easy connection to a computer to retrieve historical data.
