In industries such as petrochemical, coal mining, and natural gas, where there is a risk of flammable and explosive hazards, explosion-proof industrial endoscopes play a critical role in ensuring the safe operation of equipment and promptly identifying internal defects. However, with numerous products available in the market and complex parameters to consider, making the right choice can be challenging. In this article, we will analyze the key parameters of Coantec's explosion-proof industrial endoscopes to help you make an informed decision.

1. Explosion-Proof Parameters: The Foundation of Safety
The explosion-proof rating is a core parameter for explosion-proof industrial endoscopes. Coantec products commonly feature the Ex ic ⅡB T4 Gc certification, which holds significant meaning:
"Ex" stands for explosion-proof.
"ic" indicates an intrinsically safe electrical device, meaning that even if a fault occurs within the device, the electrical sparks or thermal effects will not ignite an external explosive gas environment.
"ⅡB" specifies suitability for Class ⅡB explosive gas environments, such as those containing common gases like ethylene and dimethyl ether.
"T4" specifies that the device's maximum surface temperature does not exceed 135°C, preventing explosions caused by high temperatures.
"Gc" indicates suitability for Zone 1 and Zone 2 hazardous areas, ensuring safe operation in different hazardous environments.
Coantec achieves these high standards through optimized circuit design and the use of special materials. The internal circuits are designed with intrinsic safety principles to limit energy output and prevent sparks that could ignite explosive gases. The outer casing is made of anti-static, high-temperature-resistant engineering plastics, further enhancing safety.

2. Imaging Parameters: The Key to Accurate Inspection
Imaging quality directly impacts inspection effectiveness. Coantec's explosion-proof industrial endoscopes are equipped with high-pixel image sensors, with some models featuring over one million pixels. Combined with advanced optical lenses and image processing algorithms, these devices provide clear and detailed images. Even in dimly lit and complex pipeline environments, they can clearly display fine defects such as 0.01mm-level cracks and corrosion spots, enabling inspectors to accurately assess equipment conditions.
Additionally, the products offer excellent color reproduction accuracy, reflecting the true colors and conditions of internal materials. This prevents misjudgments caused by color deviations. For example, when inspecting the internal coating of a chemical reactor, accurate color reproduction helps determine whether the coating is aging or peeling.
3. Probe Parameters: The Guarantee for Complex Environments
The probe is the component that directly contacts the inspection object, making its parameters critical. Coantec offers a variety of probe specifications, with diameters ranging from Φ0.9mm to Φ8mm. The ultra-thin Φ0.9mm probe is suitable for inspecting narrow gaps and small holes, while the Φ8mm probe is better suited for large-diameter pipelines and internal container inspections.
The flexibility of the probe is also important. Coantec's bendable probes can achieve bending angles of up to 180° or more, combined with 360° rotation functionality, allowing them to flexibly navigate complex structures for comprehensive and gap-free inspections. The probe material is made of high-strength, wear-resistant materials, such as tungsten alloy wire, ensuring a long service life even in harsh industrial environments.
4. Other Parameters: Enhancing User Experience
In terms of battery life, Coantec's explosion-proof industrial endoscopes feature high-capacity batteries or dual-engine power designs, allowing for extended inspection periods without frequent recharging. Some models can operate for over 5 hours on a single charge, meeting the demands of a full day of routine inspections.
The protection rating is another important parameter. Coantec products typically meet the IP67 waterproof and dustproof standard, ensuring normal operation even in dusty, humid, or temporarily submerged environments. This adaptability makes them suitable for harsh industrial sites such as petrochemical and coal mining facilities.
Understanding these key parameters is essential when selecting an explosion-proof industrial endoscope.
