The HHP-2000 Series handheld air pressure meter is designed for one-handed industrial or laboratory use. The custom molded case allows this manometer to withstand continual heavy use and operation in industrial or humid environments. Each unit has a high-contrast LCD with a backlight feature, allowing readings to be seen in most applications. All differential models can measure gauge or vacuum pressures, as well as differential, by venting the low and high ports to atmosphere, respectively. Each unit is autoranging, offering great resolution and accuracy, the company says. Three models are available: the HHP200x, the HHP202x and the HHP208x. Datalogging features enable readings to be taken (up to 250 points), stored, retrieved and downloaded.
