台湾贝克莱斯BK8386P双输入差压计是一款高精度、多功能的差压测量仪器，广泛应用于冷冻空调压力量测维护、空气及天然气体压力量测等领域。

该设备具备双输入功能，可同时测量两个压力点，并通过双显示P1/P2、P1-P2的方式，直观呈现压力差，便于监控与操作。它提供4种可选择的压力单位，包括InWC、mmWC、mBar、psi，满足不同场景下的测量需求。此外，归零功能可确保测量的准确性。

在性能方面，其精确度为±1.5% FS，操作环境温度范围为0至50°C（32°F至122°F），适用于干燥、非腐蚀性气体。设备采用9V电池供电，电池寿命可达200小时，并带有低电压显示功能。其外壳具有耐冲击性，尺寸为180mm（高）×60mm（宽）×30mm（厚），重量约为195克（含电池），便于携带和使用。

The Taiwan Beckles BK8386P dual-input differential pressure gauge is a high-precision and multifunctional differential pressure measuring instrument, widely used in the measurement and maintenance of refrigeration and air conditioning pressure, as well as the measurement of air and natural gas pressure.

This device is equipped with a dual-input function, capable of measuring two pressure points simultaneously and intuitively presenting the pressure difference through dual display P1/P2 and P1-P2, facilitating monitoring and operation. It offers four selectable pressure units, including InWC, mmWC, mBar, and psi, to meet the measurement needs of different scenarios. In addition, the zeroing function ensures accurate measurement.

In terms of performance, its accuracy is ±1.5% FS, and the operating environment temperature range is 0 to 50°C (32°F to 122°F), suitable for dry, non-corrosive gases. The device is powered by a 9V battery, with a battery life of up to 200 hours and a low voltage display function. Its housing is impact-resistant, with dimensions of 180mm (height) × 60mm (width) × 30mm (thickness) and a weight of approximately 195 grams (including battery), making it convenient to carry and use.
