Audited Supplier The state-of-the-art Vaisala Indigo520 Industrial Dew Point Probe Transmitter Humidity Temperature Sensor from Hangzhou Xinjian Electronic Co., Ltd. is an industrial-grade, robust transmitter designed to accommodate one or two Vaisala Indigo-compatible probes. This versatile device measures humidity, temperature, dew point, carbon dioxide, ***, and moisture in oil. Additionally, with an extra module, it can measure barometric pressure, making it an indispensable tool for precise environmental monitoring.
Designed to perform seamlessly even in the harshest conditions, the transmitter features a wide operating temperature range, an IP66-rated corrosion-resistant metal enclosure, and an optional touchscreen display made of strengthened (Ik08) glass. It withstands commonly used cleaning chemicals, such as isopropanol and 30% liquid ***, ensuring reliable and consistent performance.
• Flexible Powering Options: Choose from Power over Ethernet, protective extra-low voltage, or AC (mains) power to best suit your installation needs.
• Precision Barometric Pressure Sensor: Available with the highly accurate and stable Vaisala BAROCAP barometric pressure sensor.
• Non-display Model: Opt for the non-display model featuring an LED indicator for a streamlined, efficient setup.
