PS-4252 wireless digital-display ethanol sensor
The PS-4252 wireless ethanol sensor with digital display measures gaseous ethanol concentrations up to 3%. In biology and environmental-science laboratories, students can learn about anaerobic respiration by measuring ethanol from bacterial or yeast fermentation. Physics students can explore combustion and thermodynamics, while chemistry students can compare vapor compositions above simple solutions. The sensor supports research into fermentation, respiration, solution properties, and alternative-energy production. Its bright OLED display is clearly visible even outdoors, providing live measurements simply by switching the sensor on. It also streams live data and supports remote logging with PASCO software for deeper analysis. Note: This is a gas sensor and must not be immersed in liquids. Exposure to ethanol gas above the recommended upper concentration of 3% may shorten the sensing element's life.

Sensors
Brolight
Interface Type: USB or Bluetooth 2.0 Interface: 4 (2 PASPORT interfaces, 1 voltage interface, 1 temperature interface)
The PS-2011 SPARKlink dual-channel Bluetooth interface lets teachers and students connect their devices by USB or Bluetooth to any of more than 70 PASPORT sensors in the PASCO range. Data are acquired with SPARKvue or PASCO Capstone. Teachers and students can use desktop or laptop computers running either program, or Bluetooth-enabled iOS or Android devices running the SPARKvue app. Note: SPARKlink Air connects to Google Chromebooks by USB but does not support Bluetooth connection to them.

Gas mass flow controllers-3660 series
Sensors
Csl-vacuum
Flow-rate range [Different flow units at the two ends retained as in the source, without conversion]: 10SCCM~100SLM Gas/fluid: N2, AIR, H2, HE, AR, O2, CO2, etc. Electrical connection: Dsub 9-pin
An internal sensor measures gas flow in real time and compares it with the setpoint. The controller rapidly actuates a regulating valve, forming a closed loop that stabilizes actual flow precisely at the target.

Fully integrated 4-channel DVS optical module
Sensors
Oe-photonics
Sensing distance: typical:20 km Number of detection channels: 4 channels Modulation mode: External modulation
For multichannel, fully integrated distributed vibration sensing (DVS), the DVS-AOM-L series uses an ultra-narrow-linewidth laser with optimized optomechanical/electrical integration. Serial-port parameter configuration, high integration, environmental-interference resistance, compact size, and convenience are provided. Sharing a narrow-linewidth laser reduces multichannel costs, particularly for demanding sensing applications. Custom solutions and specifications are available to sensor-equipment manufacturers.
