Checking the dew point with the HG970 series portable dew point meter from HENGKO is a precise, efficient, and reliable process designed for both industrial field inspections and laboratory-quality measurements. The HG970 series offers various probe configurations to suit a wide range of applications, from general HVAC systems to high-temperature drying environments. Below is a step-by-step guide and technical overview of how the dew point measurement is conducted using this instrument.
The HG970 series includes multiple probe types (e.g., replaceable, sharp, long, split) and temperature ranges (-30°C to 120°C), allowing users to choose the most suitable model based on their measurement environment. For example:
HG970 / HG972: Ideal for general industrial and HVAC applications.
HG981 / HG982: Recommended for high-temperature environments (80–120°C), such as lithium battery drying rooms and gas pipelines.
Ensure the device is powered (via external power supply or field setup).
Connect the probe securely to the test point, pipe port, or environmental chamber.
For accurate results, avoid exposing the sensor to sudden humidity shocks or contaminants like oil or dust before the reading stabilizes.
Once connected, the HG970’s built-in sensing module continuously samples the air or gas, measuring parameters such as:
Dew Point Temperature (°C or °F)
Relative Humidity (%RH)
Ambient Temperature (°C/°F)
These values are calculated using HENGKO’s advanced polymer capacitive or ceramic sensor technology, offering fast response time dan high accuracy even in dynamic or high-moisture environments.
If the model includes an LCD or digital interface (optional), the readings are displayed in real-time. For models without a display, the output is transmitted via:

some questions about Dew Point Meter you like to know
A Dew Point Meter is a precision instrument used to measure the dew point temperature — the temperature at which air or gas becomes saturated with moisture and water vapor begins to condense into liquid.
It works by sensing the relative humidity and temperature of the environment or gas stream, then calculating the dew point based on the current saturation level. Most modern dew point meters use capacitive or ceramic sensors for real-time measurements, offering high accuracy and stability across a wide range of industrial applications.
Dew point measurement is critical for moisture control, especially in applications where excess humidity can lead to equipment failure, corrosion, product spoilage, or safety risks.
Industries such as sistem udara terkompresi, pharmaceuticals, lithium battery manufacturing, semiconductors, and food packaging depend on dew point monitoring to ensure dry environments and gas purity. In compressed air lines, for example, a low dew point prevents water buildup, which could otherwise damage tools and contaminate end products.
Titik embun is the absolute temperature at which air becomes saturated and water vapor condenses, while humidity (usually relative humidity) is a percentage expressing how much moisture the air currently holds compared to its maximum capacity at a given temperature.
In simple terms:
Titik embun tells you how much moisture is actually in the air (in °C or °F).
Relative humidity tells you how close the air is to saturation (in %RH).
Dew point is more accurate for industrial applications, especially when monitoring drying processes or compressed air systems.
In industrial compressed air systems, the target dew point depends on the drying method dan application sensitivity:
| Aplikasi | Recommended Dew Point |
|---|---|
| General industrial use | -20°C to -40°C |
| Instrumentation or electronics | -40°C to -70°C |
| Medical/Pharma cleanrooms | ≤ -40°C |
| Standard shop air (non-critical) | 0°C to -10°C |
A lower dew point means drier air, which is essential for high-performance or sensitive operations. The dew point meter helps monitor this and ensure system compliance.
Yes. Most dew point meters — including advanced portable models — can be used to measure dew point in a variety of non-corrosive gases, such as nitrogen (N₂), argon (Ar), carbon dioxide (CO₂), and compressed natural gas (CNG).
However, it is important to verify:
Sensor compatibility with the target gas
Pressure rating of the probe or housing
Flow regulation to avoid sensor contamination
Some models, like the HENGKO HG970 series, offer custom probe materials and protective filters for specialized gas monitoring applications.
For most industrial and professional uses, dew point meters should be calibrated every 6 to 12 months, depending on usage frequency, environmental conditions, and accuracy requirements.
Regular calibration:
Ensures data reliability
Maintains regulatory compliance (e.g., ISO, GMP)
Extends the lifespan of the sensor
HENGKO and other manufacturers often offer traceable calibration services and replacement sensors for field units.
Typical high-quality portable dew point meters can measure within a range of:
-80°C to +60°C (or -112°F to +140°F)
For example, the HG970 series by HENGKO is commonly used to monitor dew point ranges from -60°C to +60°C, making it suitable for most industrial air and gas drying applications. Some lab-grade mirror hygrometers may extend lower, but portable models balance range with portability and cost-effectiveness.
Using a portable dew point meter is straightforward:
Power on the device (battery or external power).
Connect the probe to the sample point or open environment.
Allow stabilization time (usually 30 seconds to a few minutes).
Observe the real-time dew point reading on the display or via signal output.
Log or export data if required (some models offer USB or Bluetooth).
Always make sure the sensor is clean, calibrated, and not exposed to oil, dust, or corrosive chemicals.
A Dew Point Meter is portable and often used for spot-checking or mobile diagnostics.
A Pemancar Titik Embun is a fixed, inline sensor installed for continuous monitoring in automated systems.
Dew point meters typically include a display and internal battery, while transmitters are integrated with PLCs or data loggers via analog (4-20mA) or digital (RS485/Modbus) output.
Yes — if it’s rated for industrial or field use. Look for:
IP-rated housing for dust and moisture protection
Stainless steel probe construction
Temperature range compatibility (e.g., -30°C to +120°C)
Shock-resistant casing
Models like the HENGKO HG970 series are designed for demanding conditions, including outdoor gas lines, drying towers, or factory production lines.
