PS-4204 wireless digital-display pH sensor
The PS-4204 wireless pH sensor with digital display is an essential tool for chemistry, biology, and environmental-science courses. It streams live data or stores several days of data for continuous monitoring. Its bright display lets students immediately observe solution properties. It supports activities including acid-base titration, household-chemical investigations, chemical-reaction analysis, and water-quality studies. Overview: It works reliably in laboratories or the field without cumbersome cables, reducing spill risks and improving safety. Its lithium-ion battery meets years of normal classroom use. A bright organic light-emitting diode (OLED) display lets students immediately observe solution properties with or without a computer connection. The wireless pH sensor supports acid-base titrations, household-chemical investigations, chemical-reaction analysis, water-quality studies, and more. It connects a pH probe through a BNC port, and its amplifier also accepts oxidation-reduction potential (ORP) probes, flat-surface pH probes, and ion-selective electrodes (ISE). See the buying guide for a complete list of compatible accessories.

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.
