All About High Industrial Temperature Humidity Transmitter

1.What makes the HG808 series suitable for harsh industrial environments?

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.

2. Can HG808 sensors operate reliably in high-temperature environments over 150°C?

Yes. The HG808-T series can operate from -40°C to +200°C and is designed with an ultra-high-temperature-resistant sensor. It maintains stable humidity measurements even between 100°C to 200°C. The HG808-A model also performs dew point monitoring up to 180°C, ideal for dry high-temp applications.

3. What industries typically use the HG808-T or HG808-A models?

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

4. How accurate are the temperature and humidity readings of HG808 sensors?

Accuracy is a core strength:

  • HG808-T: ±0.1°C (@85°C), ±2%RH

  • HG808-A: ±3°C for dew point across -20 to +100°C
    This high accuracy ensures precise monitoring, even in dynamic environments.

5.How should I choose the right HG808 model for extremely high-temperature environments such as kilns or flue gas pipelines?

For environments where the air temperature exceeds 150°C, traditional temperature and humidity sensors often fail due to thermal drift or sensor degradation. The Seri 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

6.What are the options for monitoring relative humidity in environments with 90–100% RH or persistent condensation?

In persistently wet or saturated air environments—such as greenhouses, swimming pools, fermentation chambers, or cleanrooms—accuracy and anti-condensation capability are critical. The HG808-H Series 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.

7.When is dew point measurement preferred over relative humidity monitoring?

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 190°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.

8.What HG808 model is best for environments with high chemical exposure (acids, vapors, solvents)?

Chemical-resistant monitoring is critical in pharmaceutical, chemical processing, and battery manufacturing. The HG808-F Series 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

9.Which model should I use for precision measurement in temperature-controlled environments like labs or pharmaceutical storage?

Choose the HG808-C Series for high accuracy and long-term stability:

  • Accuracy: ±0.1°C, ±1.5% RH

  • Temperature range: -40°C to +150°C

  • Ideal for:

    • Biopharmaceutical manufacturing

    • Calibration labs

    • Food & vaccine storage (requiring 24/7 monitoring)

    • Semiconductor packaging rooms

The model uses advanced calibration algorithms dan low-drift sensors suitable for regulated industries.

10.What’s the difference between inline dew point meters (HG808-D/G) and external probe types (HG808-A)?

  • 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.

11.What factors should I consider for selecting a transmitter for battery drying rooms or cathode/anode drying lines?

In battery plants, drying rooms require both low humidity dan 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.

12.Can one sensor be used for both high temperature and high humidity simultaneously?

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.

13.How do I ensure stable long-term performance in harsh industrial environments?

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)

  • Gunakan RS485/Modbus integration for remote diagnostics and maintenance

14.Are there customization options for unique industrial scenarios (OEM integration, flange mount, IP rating)?

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.
