Portable illuminance/luminance meter - multiple models, LuxPartner companion

LUX-100 is HZYMTECH’s portable illuminance/luminance series: LUX-100D for horizontal illuminance, LUX-100D-C for semi-cylindrical Esc (pedestrian facial recognition), LUX-100D-F for full cylindrical spatial illuminance; LuxPartner on Android, Windows and Linux provides live reading, uniformity grids, integral and timed logging with PDF export.

Which models are in the LUX-100 series?

LUX-100D Illuminance Meter - The best choice for illuminance measurement in plazas, large venues, airport lounges, station waiting rooms and commercial sites.

LUX-100D-L Luminance Meter - Contact measurement of surface source average luminance, economical and easy to use. Widely used in commercial and industrial testing for its fast and convenient operation.

LUX-100D-C Semi-cylindrical Illuminance Meter - For semi-cylindrical illuminance measurement, mainly for evaluating lighting quality for interpersonal visual communication and spatial perception; widely used in outdoor public spaces, road lighting, security lighting and sports venues.

LUX-100D-F Full Cylindrical Illuminance Meter - For average cylindrical (spatial) illuminance measurement, especially for plant lighting and agricultural research, architectural lighting analysis and design, and museum lighting evaluation.

LUX-100UV UV Illuminance Meter - Widely used in UV sources, disinfection, phototherapy, aging, NDT, lithography, curing, breeding, plant cultivation, solar UV index evaluation, etc.
UVC254nm/UVB297nm/UVA365nm multi-band detectors optional.

LUX-100IR Infrared Illuminance Meter - For irradiance/intensity measurement of IR sources in security and night vision, machine vision and industrial inspection, as well as IR remotes, IR data links and proximity sensors.

FAQ

What does the LUX-100D-C semi-cylindrical meter measure?▾

LUX-100D-C measures semi-cylindrical illuminance Esc—the average illuminance on an oriented vertical semi-cylinder. Versus horizontal lux, it better reflects facial recognition and pedestrian security, and is an evaluation metric in standards such as CJJ 45 for sidewalks.

How to choose LUX-100D-C vs LUX-100D-F vs LUX-100D?▾

Choose LUX-100D-C (semi-cylindrical) for sidewalk/plaza/security facial recognition; LUX-100D-F (full cylindrical) for architectural surround and museums; LUX-100D for horizontal task/ground illuminance only. All use lux, but different geometries—do not substitute in acceptance tests.

Which platforms does LuxPartner support and what can it do?▾

LuxPartner offers an Android app plus Windows and Linux desktops. Connect via Bluetooth on phone, or USB serial / Bluetooth on PC; live readings, uniformity grids, integral and timed logging, PDF/text export, session files shared across devices; field calibration on Android.

What height is used for field Esc measurement?▾

CJJ 45 typically places sidewalk Esc points on the centre line 1.5 m above the pavement; JGJ/T 163 often uses 1.5 m above ground for walkways/plazas. Follow the project’s cited clauses; use a leveled tripod and record orientation.

Can LUX-100 replace PPFD measurement for plant lighting?▾

No. Plant photosynthesis should be evaluated with a quantum sensor measuring PPFD (µmol·m⁻²·s⁻¹). Cylindrical/semi-cylindrical illuminance is photopic geometry for human vision and does not replace photosynthetic photon flux density.
