The pressure sensor BT66i is designed to measure absolute gas pressure. The pressure is measured via a pressure valve, which is located on the side of the box. The sensor has two measurement ranges, which can be selected using a switch.

Range: 0 ... 700 kPa, 0 ... 130 kPa
Resolution (12-bit): 0.2 kPa, 0.04 kPa

Includes: a plastic 20-ml syringe with Luerlock, two plastic tubes (5 cm and 45 cm long), a three-way valve with Luer-lock connectors, two Luer-lock connectors.

 Can be used to:
• measure pressure changes in gas-law experiments, Boyle’s andGay-Lussac’s laws,
• measure vapor pressure of liquids,
• measure air pressure for weather studies
