LS125 Multi-Probe UV Light Meter — A Versatile Solution for UVA, UVB & UVC Measurement
Measuring ultraviolet (UV) radiation accurately across different spectral bands is essential for industries ranging from UV curing and exposure control to phototherapy, plant growth lamps, and germicidal sterilization. The LS125 Multi-Probe UV Light Meter from Linshang Technology is a flexible, professional UV radiometer solution that adapts to diverse UV measurement needs through a range of interchangeable probes.
📏 What Is the LS125 UV Light Meter Host?
The LS125 is a smart, handheld UV measurement host unit designed to work with up to 12 different UV probes. Rather than being limited to a single wavelength or application, this modular system lets you change probes to measure UVA, UVB, UVC, visible blue light, and UV LED sources depending on your specific test requirements.
Unlike fixed UV meters with one built-in detector, the LS125 host intelligently recognizes which probe is connected and automatically adapts its measurement display and unit options for that spectral range.
🔍 Key Features & Strengths
✔ Multi-Probe Support — Flexibility for Every UV Band
Supports 12 different UV probes through an aviation-style connector.
Can be equipped to measure UVA, UVB, UVC, UV LED, and even visible blue light ranges.
Different probes are optimized for 254 nm germicidal lamps, 222 nm far UVC lamps, plant-growth lamps, LED curing units, and more.
✔ Comprehensive UV Data Output
Once a probe is connected, the LS125 host displays:
Real-time UV power intensity
Maximum and minimum values
Average power
Accumulated UV energy (dose)
Test duration
This makes the LS125 useful for both quick field checks and more detailed process validations.
✔ Smart Probe Recognition
The meter automatically detects the type of probe connected and configures the display accordingly — no manual setup needed for each measurement type.
✔ Portable & User-Friendly Design
Compact body with a 240 × 160 dot-matrix LCD display
Lightweight (≈ 194 g) and powered by 4 AAA batteries
Automatic shutdown after inactivity to save battery life
📊 Wide Application Range with Interchangeable Probes
The LS125 shines because it doesn’t limit you to a single UV band. Depending on the probe you choose, it can cover measurement requirements such as:
UVC germicidal lamp intensity (230–280 nm) for sterilization systems in hospitals, labs, or water treatment plants.
Far UVC lamps (210–250 nm) — safe options for occupied spaces.
UVB lamps (280–315 nm) — used in physiotherapy and plant growth lighting.
UVA and UV LED sources (315–420 nm) — common in printing, curing, and exposure applications.
Blue light probes (410–490 nm) for visible band analysis.
This modular design means one meter can replace multiple single-purpose instruments — boosting cost-effectiveness and measurement flexibility.
🛠️ Typical Use Cases
The LS125 Multi-Probe UV Light Meter is ideal for:
✔ UV curing systems quality control
✔ Germicidal UV sterilization testing
✔ Exposure and phototherapy device measurement
✔ Plant growth and reptile UV lamp radiometry
✔ LED UV LED light intensity and energy analysis
✔ Welding arc and sunlight UV evaluation
With just one versatile host unit and a set of probes, professional users can handle a wide spectrum of UV measurement challenges without needing separate testers for each application.
🏁 Conclusion
The LS125 Multi-Probe UV Light Meter Host is a flexible, professional, and future-proof UV measurement platform that adapts to whatever spectrum your task demands. Its smart probe recognition, advanced data statistics, and broad compatibility make it a reliable choice for engineers, quality managers, and technicians working with UVA, UVB, and UVC light sources across industries.
