Description
LED Light Therapy Irradiance Tester: Device Measurement with Data Logging at an Affordable Price
The advanced R-model includes a 32 000-reading memory and RS-232 PC interface for effortless data transfer and analysis.
The TES-1333R Solar Power Meter is a precision tool designed to measure solar irradiance and light intensity. Whether you’re calibrating LED light therapy devices, monitoring household sunlight exposure, or conducting professional clinical and research work, this compact meter ensures reliable results every time.
With a wide spectral response (400–1100 nm), cosine-corrected sensor, and dual unit display (W/m² or Btu/ft²·h), the TES-1333R delivers trustworthy data for therapy, solar studies, and energy testing.
Why it helps LED therapy users: It verifies device output and placement. Additionally, it supports quick comparison between panels and sessions. Therefore, dosing becomes more consistent.
How it measures: A cosine-corrected silicon sensor reads 400–1100 nm solar irradiance. Moreover, it displays in W/m² or Btu/(ft²·h) for flexibility. Resolution is 0.1 W/m² with typical accuracy ±10 W/m² or ±5%.
Key Features
- Cosine-corrected sensor for angular accuracy within 5% at <60°.
- Wide spectral response from 400 to 1100 nm.
- Dual units: W/m² or Btu/(ft²·h). (100W/m² = 10mW/cm²)
- MAX/MIN/AVG and Data Hold modes.
- 99 manual memories plus 43,000 auto-logged sets.
- RS-232 cable and software included with the R model.
- Resource TES Manufacture: TES
Data and workflow: It stores 99 manual sets or 43,000 auto-logged readings. Furthermore, the RS-232 interface and software enable PC analysis. Consequently, you can track trends across weeks. TES.com
Honest positioning: Use it for indicative checks and optimisation. It is not intended for accredited compliance under ISO 9060. Thus, clinics needing certified pyranometers should choose a higher class instrument such as our Level 1/Class A Spectrometers.
With a wide spectral response of 400–1100 nm and 0–2000 W/m² measurement range, the TES-1333R is simple to convert into mW/cm²:
Useful conversion for therapy: 1 W/m² equals 0.1 mW/cm². Therefore, 200 W/m² equals 20 mW/cm². This helps translate readings to common therapy units.
✅ Example Conversions
- Reading of 100 W/m² = 10 mW/cm²
- Reading of 500 W/m² = 50 mW/cm²
- Reading of 1000 W/m² = 100 mW/cm²
A versatile tool that offers great value under £195.
Unlike Class A laboratory meters that cost thousands, the TES-1333R provides good everyday accuracy (±5% or ±10 W/m²), making it ideal for users who simply want to check if their devices are delivering consistent and effective levels of light.
Practical Notes for LED Therapy
- Place the sensor at the treatment plane. Additionally, keep angle consistent.
- Log several minutes to capture warm-up changes. Consequently, readings stabilise.
- Record distance, mode, and time for repeatability. Furthermore, convert to mW/cm² as needed.
Why Choose TES-1333 Over Expensive Meters?
If you need absolute scientific precision, you’ll want a Class A certified Spectrometer (costing £500+). But for most light therapy enthusiasts, households, and small businesses, the TES-1333 offers reliable, consistent readings at a fraction of the price—making it one of the best entry-level tools for everyday light testing.
