Sekonic measurement and recording instruments
Sekonic instruments support lighting evaluation and measurement recording. SL Measurement's range includes the C-7000 handheld spectrometer, SP-100 universal recorder and information for existing ST-50 temperature and humidity recorders.
Choose the relevant product below for specifications, accessories and application guidance. For older equipment, provide the full model and serial number when requesting consumables or replacement options.
C-7000 spectrometer for LED and lighting measurement
Lighting evaluation involves more than brightness. Depending on the task, you may need to compare illuminance, colour temperature, colour rendering or the spectrum of a light source.
- Sekonic C-7000 handheld spectrometer — measures light spectrum, illuminance and colour characteristics for comparing LEDs and other lighting sources. Stored measurements and spectral data can be reviewed through C-7000 Utility software.
For product comparisons or installation checks, specify the light sources, expected light levels and required measurement functions. Some colour-analysis functions depend on firmware, so confirm the required modes before ordering.
SP-100 universal six-channel recorder
A universal recorder accepts different measurement signals for recording several points together. Match each channel to the connected sensor or transmitter and its signal range.
- Sekonic SP-100 universal recorder — provides six-channel recording for supported thermocouple, Pt100, current and voltage inputs. Confirm the input configuration, recording requirements and current availability.
For replacement enquiries, include the existing wiring arrangement, input types and measurement scales. Identify whether the connected sensors will be retained.
ST-50A and ST-50M thermohygrographs
The ST-50 range combines temperature and humidity measurement with paper recording. These models are discontinued; their product pages remain useful for identifying existing equipment, consumables and alternative recording arrangements.
- Sekonic ST-50A thermohygrograph — digital indication with paper chart recording. Manufacturer sales have ended; any remaining stock and consumables are subject to availability.
- Sekonic ST-50M thermohygrograph — combines paper charts with SD-card recording. New instruments are no longer available; refer to the page for consumable references and alternatives.
Chart paper, pens and replacement sensors
For ST-50 consumables, check the reference printed on the existing packaging. The ST-50A product page lists chart-paper codes, recording pens, the HEAA temperature and humidity sensor and extension-cable references.
For an unidentified component, send photographs of the part, its connection and the recorder nameplate.
Alternatives for discontinued ST-50 recorders
Select an alternative according to the records you need. The following instruments use different recording methods and are not direct interchangeable replacements.
