The HSM Features

SPECIFICATIONS and ACCESSORIES

• Foldaway Sensor system – Sensors can be rotated and stowed away in the protection of a rear compartment. This allows the module to be deployed without danger of contamination and reduces the risk of breakage.
• Removable environmental data sensor system (module) that can be easily disconnected for replacement or repair.
• All calibration data and signal conditioning electronics are contained in the sensor module.
• Liquid crystal display (LCD) with low power consumption and good contrast in sunlight as well as indoor lighting.
• Backlight for use in very low light conditions.
• The HSM is equipped with thermistor-based sensors to measure air temperature, wind speed, and solar radiation.
• Capacitive polymer-based sensor to measure humidity.
• Piezo-resistive absolute pressure sensor for measuring barometric pressure and estimating altitude.
• Fast response black globe system. Using single piece of copper of 0.15mm wall thickness. Simulated 6” Globe with fast response time.
• Environmental data may be displayed in real time.
• Unattended data logging with time stamping.
• Interfaces to a Personal Computer to allow downloading of data logs for analysis.
• Data logging results can be viewed on screen.
• Tripod mount option for data logging mode.
