Over the years, the Model VT and CVT instruments have proven themselves as the standard in the industry by OEM and other suppliers. The most versatile vacuum instrument in the Hastings product line is the Model 2002™ Dual Vacuum Sensor. This device measures from atmospheric pressure to 10-4 Torr pressure using a small, durable thin film sensor. Additional vacuum instruments offered by Hastings Instruments include absolute pressure sensors, which are independent of gas composition.

An economy line of vacuum gauges and vacuum gauge tubes which have also been produced for industries focused on lowering system cost to end users. All Hastings vacuum instruments use precision sensing devices to provide maximum accuracy.

The heart of the system is a replaceable sensor which virtually eliminates long downtimes due to clogging, the most common cause of failure in the industry. The modular design also offers adjustable range capabilities, in-line filtration, and replaceable electronics to allow users maximum flexibility in adjusting their system for changing requirements. Current designs can accommodate flow rates from 10 SCCM to 15,000 SLPM, fast responding or zero overshoot electronics.

Other mass flow instruments include mass flow meters and mass flow controllers for specific applications, such as low pressure drop, high capacity flow, high temperature, high pressure, and hermetically sealed systems. These mass flow instruments are an asset to any industry requiring accurate gas measurement and/or control. Primary industries include R&D process flow, vapor deposition, leak testing, gas blending, pollution monitoring, medical research, gas chromatography, and semiconductor support processes.
