B-530 Humidity Sensor for Graphtec Data Loggers

Measures 0 to 100% Relative Humidity

Connect the B-530 humidity sensor to any GL240, GL260, GL840, GL860, or GL900 for humidity measurements.

• Measures 0 to 100% RH
• Accuracy of ±3% RH at 25°C
• 3 meter length (9.84 feet)
• Power the B-530 via the data logger's 5V power supply
• Connects to any available analog voltage channel on the data logger

With a 3 meter cable, the B-530 is powered via the data loggers 5V supply and connects to an available analog voltage channel.
