The HG808 series is engineered with robust materials like 316L stainless steel probes and cast aluminum housings, providing high resistance to heat, humidity, and chemical exposure. Models like HG808-T and HG808-A are specifically built for extreme temperatures up to 200°C and dry, high-temperature dew point environments, making them ideal for kilns, ovens, coking gas pipelines, and more.
Yes. The HG808-T series covers -40°C to +200°C. Recommended operating range is +85°C to +180°C; below +85°C accuracy is not specified, and +200°C is for short-term use. It is designed with an ultra-high-temperature-resistant sensor for demanding thermal processes. The HG808-A model also performs dew point monitoring up to 180°C, ideal for dry high-temp applications.
These models are widely used in:
Furnace kilns and incinerators
High-temp ovens and drying systems
Steel and chemical processing plants
Gas pipelines for coking or synthesis
Power generation facilities requiring dew point control
Accuracy is a core strength:
HG808-T: ±0.3°C (@85°C), ±2.5%RH
HG808-A: ±3°C for dew point across -20 to +100°C
This high accuracy ensures precise monitoring, even in dynamic environments.
For environments where the air temperature exceeds 150°C, traditional temperature and humidity sensors often fail due to thermal drift or sensor degradation. The Serie HG808-T is specifically engineered for such cases, supporting up to 200°C and equipped with a 316L stainless steel probe that withstands thermal stress and provides stable humidity collection even between 100°C and 200°C.
Typical use cases include:
Industrial kilns (ceramics, steel, glass)
High-temp drying ovens
Flue gas exhaust pipelines in power or chemical plants
In persistently wet or saturated air environments—such as greenhouses, swimming pools, fermentation chambers, or cleanrooms—accuracy and anti-condensation capability are critical. The Serie HG808-H is designed with:
A robust stainless steel sensor housing
Anti-condensation coating
High humidity tolerance up to 98% RH
Unlike standard RH sensors that degrade or saturate near 95% RH, the HG808-H provides stable readings in these tough environments.
Dew point is the temperature at which air becomes saturated and condensation begins. In very dry or pressurized gas systems, RH becomes less meaningful and dew point is the key metric.
You should choose dew point transmitters like:
HG808-A Series: for high-temperature and dry applications up to 180°C
HG808-D/G Series: for ultra-low dew point detection (down to -60°C), ideal for:
Glove boxes
Lithium battery production
Semiconductor packaging
Industrial dry air systems
Dew point measurement offers more meaningful, pressure-independent metrics in these scenarios.
Chemical-resistant monitoring is critical in pharmaceutical, chemical processing, and battery manufacturing. The Serie HG808-F is built for such use:
Operates at -40 to +120°C and 0–100% RH
Withstands corrosive environments with a chemical-resistant sensor enclosure
Ideal for applications like:
Cleanrooms (ISO 7–9)
Battery production (e.g., lithium or NiMH)
Chemical labs or solvent storage areas
Choose the HG808-C Series para high accuracy and long-term stability:
Accuracy: ±0.1°C, ±1.5% RH
Temperature range: -50°C to +150°C
Ideal para:
Biopharmaceutical manufacturing
Calibration labs
Food & vaccine storage (requiring 24/7 monitoring)
Semiconductor packaging rooms
The model uses advanced calibration algorithms y low-drift sensors suitable for regulated industries.
HG808-D/G: Inline installation within closed systems like compressed air lines or glove boxes; ideal for low dew point (< -20°C) and precise process control.
HG808-A: External probe, suited for open or semi-open high-temp systems, such as heated drying chambers or hot gas ducts, where dew point indicates dryness or risk of condensation.
In battery plants, drying rooms require both low humidity y corrosion resistance. Recommended options:
HG808-F: For general drying room humidity monitoring with chemical exposure
HG808-D: For inline dew point monitoring, especially in inert gas or vacuum systems
HG808-G: For ultra-dry, low-temp gas streams
Look for dew point range below -20°C and fast response time in these scenarios.
Typically no, as sensors that handle extreme temperatures (like HG808-T, up to 200°C) are not suitable for saturated humidity at those temps. Similarly, high humidity sensors (like HG808-H) are optimized for moderate temperatures up to 100°C.
Recommendation: Evaluate your application priorities—if temperature is extreme, choose HG808-T and disregard RH accuracy. For wet high-humidity use, choose HG808-H and operate within the specified range.
Here are some best practices:
Choose models with industrial-grade sensors (HG808 series uses sensors rated for stability and drift resistance)
Ensure proper shielding or enclosures if exposed to corrosive vapors or condensation
Plan for annual recalibration in regulated environments (e.g., pharma or food industries)
Utilice RS485/Modbus integration for remote diagnostics and maintenance
Yes. HENGKO supports full OEM customization, including:
Custom sensor probe lengths (up to 1 meter)
Threaded or flanged mounts
Custom output signals
Enhanced IP67/IP65-rated housings
Special calibration ranges or field-specific enclosures
These are often required for system integrators or equipment manufacturers in HVAC, gas analysis, or automation industries.
