Chroma meter · illuminance & colour
The CLM-200H measures light the way a lighting engineer needs it: illuminance from 0.1 to 200,000 lx, correlated colour temperature from 1,500 to 25,000 K, CIE1931 and CIE1976 chromaticity, tristimulus values, dominant wavelength, colour purity and luminous flux — read live from one optical head and shown together on a single colour screen.
- 0.1 – 200,000 lx
- 1,500 – 25,000 K
- CIE1931 / CIE1976
- xy ±0.003
- SD card logging
- 2,200 mAh
Why it stands out
- Illuminance and colour in one readingEv, CIE1931 (x,y), CIE1976 (u′,v′), colour temperature, dominant wavelength, purity and luminous flux are shown together on one screen.
- 0.1 – 200,000 lx, four auto rangesSwitches ranges automatically from 5 lx / 0.5 fcd, so dim indicator panels and bright LED engines are measured on the same instrument.
- ±2 % of reading, xy ±0.003Accuracy verified against standard illuminant A at 500 lx, with xy repeatability of ±0.0005 for tight binning work.
- Correlated colour temperature 1,500 – 25,000 KWarm dimming lamps through to cold-white LED modules, with the temperature curve and multi-point settings on screen.
- Colour difference against a referenceΔ(XYZ), Δ(Evxy), Δ(Evuv), ΔEv, ΔTc and Δuv against the stored sample, for batch-to-batch comparison.
- Logs on SD card, analyses on PCThe meter stores the latest nine readings and writes every capture to SD as a text file; the supplied software turns it into an Excel sheet.
What it measures
| Parameter | Range / unit |
|---|---|
| Illuminance (Ev) | 0.1 – 200,000 lx / 0.01 – 20,000 fcd |
| Integral illuminance | Evh / Evm (integrated over hours or minutes) |
| Correlated colour temperature (Tc) | 1,500 – 25,000 K |
| Chromaticity coordinates | CIE1931 (x, y) and CIE1976 (u′, v′) |
| Tristimulus values | X, Y, Z |
| Dominant wavelength (λd) | Displayed with the spectral range 360 – 780 nm |
| Colour purity (Pe) | Percentage of the dominant wavelength |
| Luminous flux (Φ) | lm |
| Colour difference | Δ(XYZ), Δ(Evxy), Δ(Evuv), ΔEv, ΔTc, Δuv |
| RGB | RGB values plus RGB colour-space graph |
Colour difference is calculated against the stored reference sample, so a new batch of LED modules can be compared to the approved one without leaving the meter.
Display, Logging & PC Software
Six real-time screens cycle with the up and down keys: a parameter screen, an illuminance curve against a standard value, integral illuminance, CIE1931 and CIE1976 colour-space plots, and an RGB plot. HOLD freezes a reading and writes it to the SD card; MAX keeps sampling until you stop it and reports the highest and lowest value with the time each one occurred.
- 6 real-time screens
- HOLD capture
- MAX / MIN with timestamps
- Standard illuminance target
- Latest 9 readings
- SD card TXT export
- Excel via PC software

FAQ
What exactly does the CLM-200H measure?
Illuminance, correlated colour temperature, chromaticity coordinates, tristimulus values, dominant wavelength, colour purity, luminous flux, RGB values and colour difference — all from the same optical head.
How accurate is it?
Illuminance is specified at ±2 % of reading and chromaticity at xy ±0.003, measured at 500 lx under standard illuminant A. Repeatability is ±2 %+1 digit for Ev and ±0.0005 for xy.
Do I need a dark room or a jig?
No. Point the measuring lens straight at the light source; the reading is live. A tripod socket on the body keeps the head steady for long integration or MAX captures.
Can it record a batch of measurements?
Yes. Each capture is written to the SD card as a text file, and the meter keeps the latest nine readings in memory for quick recall. The PC software imports the file and exports Excel.
Can I compare against a target illuminance?
Yes. Set a standard illuminance value in the menu and the display shows the deviation and the ratio against that target in real time — useful for production-line pass/fail checks.
How is it powered?
A built-in 2,200 mAh lithium battery, charged over Micro USB with the supplied adapter. The same port carries data to a PC.
Which units does it use?
Illuminance in lux or foot-candles (lx / fcd), colour temperature in kelvin, wavelength in nanometres, flux in lumens. The interface runs in English or Simplified Chinese.
