Handheld Gas Dew Point Meter Runlai DPH300 High Accuracy Trace Water Analyzer Micro Water Tester with Robust Metal Housing, Customizable Detector for Industrial Gas Dew Point Measurement
The RL-DPH300 handheld dew point meter is an intelligent analyzer powered by a microprocessor. It uses a thin-film capacitive measurement principle to accurately measure the moisture content in mixed gases. The device is compact and easy to carry, featuring a clear color screen and a user-friendly menu. Its core sensor boasts fast response, high measurement accuracy, and a long service life. It also includes a built-in temperature compensation function, effectively ensuring measurement stability in different environments.
Measurement Principle
Thin-film Capacitive Ceramic Humidity Sensor | The core of this sensor is a ceramic thin-film medium that is sensitive to water molecules. When water vapor molecules in the environment penetrate and adsorb onto this medium, it causes a change in its dielectric constant, which directly results in a change in the sensor's capacitance value. By precisely measuring this change in capacitance, the instrument can calculate the corresponding humidity or dew point value.
| Basic Parameters | |
|---|---|
| Measurement Principle | Thin-film Capacitive Ceramic Humidity Sensor; |
| Measurement Range | Range can be selected from 60.0°C to 60°C) |
| Accuracy | ±1.0°C FS |
| Repeatability | +1°C |
| Stability | ±1%/7 days |
| Sample Gas Flow Rate | (2 + 0.5) L/min |
| Sample Gas Pressure | 0.05MPa ≤ Inlet Pressure ≤ 0.25MPa |
| Response Time | T90 ≤ 3 minutes; |
| Operating Power Supply | 12VDC |
| Dimensions | 99.5mm (width) * 208mm (height); |
| Charging Power Supply | (220 + 22)VAC, (50 + 5)Hz, with built-in charging protection |
| Service Life | >12 months (under normal operating conditions as specified); |
This principle allows for direct measurement of the water vapor partial pressure in gases, making it fast-responding and highly stable.
