PCE-WB 20SD is a multifunction data-logging hygrometer. This hygrometer measures indoor / outdoor wet bulb globe temperature (WBGT), black globe temperature (TG), wet bulb temperature (WB), dew point temperature, air temperature (TA) and relative humidity. Thus, this multipurpose data-recording hygrometer is an ideal tool for evaluating heat stress risks in different work environments.

• 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

PCE-330 is a multifunction digital hygrometer or hygro-thermometer with a quick-response sensor for determining ambient temperature, relative humidity and dew point temperature. Equipped with an easy-to-read dual display, this data-logging indoor air quality (IAQ) meter features a large internal memory with storage for up to 16,000 recorded values.
