PM2.5 Test
PM2.5 Test system is Equipment for monitoring small and small particles in air ， Regular maintenance is therefore required to ensure normal work and accuracy 。 Below is Some recommended maintenance steps ： 1. Regular cleaning equipment ： External surfaces and sensors of regular cleaning equipment ， Ensure that no dust or dirt impact detection is accurate 。 A special cleaning sheet or soft brush can be used to wipe the surface of the device 。 2. Calibration equipment ： Regular calibration of equipment ， To ensure the accuracy of the results 。 The calibration process will need to follow the equipment instructions ， Usually, special calibration gases are required. 。 3. Replace Filter ： If there's a filter in the device ， Need to replace filters regularly to ensure their filtering effect 。 It is generally recommended that the filter be replaced every three months. 。 4. Check the connection. ： Periodic inspection of equipment connections ， Make sure the connection is solid and undamaged. 。 The damaged connection could lead to inaccurate detection. 。 5. Regular maintenance ： Periodic inspection of the operation of equipment ， Ensure that all functions are normal 。 If you find out that the device is operating abnormally ， Timely contact with the manufacturer or maintenance staff for maintenance 。 6. Ensuring an environment is appropriate ：PM2.5 The environment of the detection system should be kept dry 、 Good ventilation. ， Avoiding direct sunlight or high humidity 。 Maintenance PM2.5 It's vital that the system is working. ， Only when equipment is well maintained and maintained ， It's the only way to ensure the accuracy and reliability of the results. 。

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.

A solid-state laser is one of the most common and reliable laser types used in modern industry, medical equipment, and scientific research. Unlike gas or fiber lasers, it uses solid materials as its gain medium to generate stable, high-brightness laser beams. Thanks to its high precision, long lifespan, and compact structure, solid-state lasers have become a mainstream solution for high-precision laser processing and optical systems.
In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
In UV laser testing, UV spectroscopy and lithography optical experiments, excessive light intensity will lead to detector saturation, optical component damage and overexposed imaging.
