PS-3211A wireless voltage sensor
The PS-3211A wireless voltage sensor is well suited to investigating core concepts in electricity, voltage, and basic circuits. It measures voltages up to ±30V and has built-in overload protection, with high-speed sampling when connected by USB. Paired with a wireless current sensor, the two devices let students explore Ohm's law, series and parallel circuits, and more. In chemistry, the sensor helps students study oxidation-reduction reactions, electrolytic-cell potentials, and the effects of solution concentration on the generated potentials. Measuring the potential difference between two half-reactions separated by a salt bridge introduces students to the driving forces behind modern batteries.

PS-2011 dual-channel Bluetooth interface 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.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
