HT Instrument HT309 Digital Luxmeter with Illuminance Measurement of LED Sources

Description

The HT Instruments HT309 is a digital, handheld light meter, not a clamp meter, used for measuring the illuminance of both standard and multicolored LED light sources. Its silicon photodiode sensor is connected to the main unit via a cable, allowing for flexible positioning.

Key Features

• LED measurement: Can measure LED light sources of various colors by setting the appropriate color correction factors.
• High range: Capable of measuring up to 400,000 lux.
• Data functions: Includes data hold to freeze readings, and maximum, minimum, and average functions to track measurements over time.
• Memory: Features an internal memory to save measurement results.
• Auto-ranging: Automatically selects the correct measurement range.
• Automatic power off: Conserves battery power by automatically turning off after 5 minutes of inactivity.
• Compliance: Complies with international CIE standards on spectral response, according to Class A guidelines.
