Overview
LANDTEK DP29-SF6 mirror dew point measuring instrument is a professional dew point measuring instrument based on the principle of subcooled mirror, specially designed for dew point measurement of sulfur hexafluoride SF6. The instrument ensures direct and accurate measurement of actual temperature through semiconductor refrigeration technology and is suitable for a variety of industrial environments.
Features
1. Adopt the principle of subcooled mirror measurement to eliminate system inertia and hysteresis errors and ensure measurement accuracy.
2, system stability, no repeability calibration.
3. Built-in electronic flowmeter to monitor the injection gas flow in real time.
4. Support USB data cable output and RS-232 data cable output for easy communication with PC.
Principle
Based on the principle of subcooled mirror, the instrument chills down the mirror surface through semiconductor refrigeration technology. When the water vapor in the gas condenses on the mirror surface, it directly measures the dewpoint temperature, thus accurately reflecting the actual humidity conditions.
Applications
SF6 dew point measurement
Steps
1. Press the mode conversion button, go to the LCD display "CH", and manually check the mirror surface.
2. Press the refrigeration test button (open the measurement head, at the mirror inspection) to manually check the instrument.
Notice
• The environment temperature should be used in the range of 0 ° C to 50 ° C.
• The environment humidity is up to 90% and there is no condensation.
• The recommended intake air flow is 30L/h to 40L/h.
• The intake pressure range is 10mbar~ 10bar (1kpa~ 1Mpa).
Make sure the voltage is 220VAC +/- 10%, 50/60Hz.
