PCE-EM 888 is a portable handheld hygrometer ideal for monitoring environmental conditions and the performance of heating, ventilation and air conditioning (HVAC) systems. This multi-functional digital device is used to measure wind speed, volumetric air flow, temperature, relative humidity, light and barometric pressure.
Due to its compact and lightweight design, this hygrometer is a true pocket weather station that can be used almost anywhere. With just the touch of a button, measurements are displayed on the easy-to-read 8 mm (0.32″) LCD screen with back-light. The device also features MIN/MAX functionality. Thus, this user-friendly hygrometer has many practical applications for monitoring weather conditions outdoors at construction job sites, farms, marinas and more. In addition, this multi-purpose meter can be used for indoor air quality (IAQ) monitoring.
A high-precision type K thermocouple sensor enables fast temperature measurements. The impeller ensures accurate wind speed measurements. While measuring the wind speed, the device always simultaneously measures the temperature of the air flow. The hygrometer also has a relative humidity sensor. The monolithic silicone-based pressure sensor allows for measurement of the barometric or atmospheric pressure. A light sensor completes the range of measuring capabilities for this multi-use tool.
