PS-3217 wireless oxygen/humidity/temperature sensor
The PS-3217 wireless oxygen/humidity/temperature sensor measures gaseous oxygen (O₂) concentration, humidity, and air temperature for a range of biology, environmental-science, and physiology activities. Accurate and easy to use, the wireless oxygen sensor is ideal for studying photosynthesis, respiration, and the oxygen cycle. Remote data logging allows experiments to continue beyond normal laboratory hours, readily providing hours or days of data for student analysis. In addition to oxygen concentration, built-in sensors measure ambient temperature and humidity. Store the sensor in a sealed bag with little air space to extend the sensing element's service life.

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.
