Overview
Gasboard-2503 is a TDLAS laser dew point sensor measuring H2O and outputting dew point from -60 to -20℃ with ±0.5℃ accuracy and <2 s response (flow-through), for lithium battery dry rooms, production equipment and dry air or nitrogen lines. Flow-through and diffusion versions, low power and RS485, TTL or 4-20 mA outputs ease integration.
Key Features
- TDLAS technology
- High measurement accuracy of ±0.5°C
- Fast response and high stability
- Built-in high-precision temperature sensor and temperature compensation algorithm
- Flow-through and diffusion configurations
- Low power consumption
- RS485, TTL and optional 4–20 mA output options
