Description:
Introducing the versatile psychrometer, a sophisticated data-logging thermo-hygrometer perfect for accurately measuring both indoor and outdoor environmental conditions This essential device tracks a variety of metrics including wet bulb globe temperature (WBGT), black globe temperature (TG), wet bulb temperature (WB), dew point temperature, air temperature (TA), and relative humidity
Ideal for assessing heat stress levels in various work settings, it serves as a valuable tool for indoor air quality (IAQ) inspectors monitoring heating, ventilation, and air conditioning (HVAC) system performance.
The psychrometer boasts a large, easy-to-navigate LCD display with a green backlight for enhanced visibility
Equipped with a programmable WBGT alarm system, it provides auditory and visual alerts to ensure that workers are informed of potential hazards promptly Users can choose between manual (push-button) or automatic sampling settings, adjustable from 1 to 3600 seconds Additionally, it supports SD memory cards ranging from 1 to 16 GB for convenient data storage.
Stay protected and informed with this essential heat index monitor.
Features and Benefits:
•For real-time or long-term temperature and humidity measurement applications.
•Temperature can be displayed in metric or imperial units, i.e., degrees Celsius (°C) or degrees Fahrenheit (°F).
•Maximum, minimum, data hold and automatic power off (can be disabled) functions.
•Programmable WBGT alarm setting with audible and visual alerts.
•Manual (push-button) or automatic (adjustable 1 ... 3600 sec) sampling.
•SD card memory (1 ... 16 GB) allows for quick and easy data transfer to a PC.
•Measuring indoor/outdoor wet bulb globe temperature (WBGT).
•Assessing heat stress risks in different work environments.
•Indoor air quality (IAQ) inspections for HVAC systems.
