Description

Introducing the HI97500 Portable Lux Meter

The HI97500 is a portable lux meter designed for straightforward and rapid light measurements. Its rugged and water-resistant body makes it suitable for frequent outdoor use. This instrument comes with a light sensor connected to the meter by a flexible coaxial cable, which allows for measurements to be taken from a distance without any interference from the operator. The device is user-friendly and includes several features that enhance its practicality, such as an automatic shut-off function after 7 minutes of inactivity and a low battery indicator.

Ease of Operation and Key Features

Operating the HI97500 is simple and intuitive. To turn the meter on or off, you simply press the ON/OFF key. The device features three different measurement ranges, which can be easily switched by pressing the RANGE key. This allows users to select the best resolution for their specific environment. If the “1” symbol appears on the LCD, it indicates that a change in the measurement scale is necessary. The meter’s battery life is approximately 200 hours of continuous use, and a blinking “V” on the LCD alerts the user when the battery is running low.

Light Measurement and Technology

The HI97500 measures illuminance in lux scale and is capable of measuring up to 200 Klux for reliable outdoor readings. The light sensor is a human-eye-response silicon photodiode. For accurate measurements, the photosensor is designed with both cosine and color correction. The cosine correction accounts for the effects of light hitting the sensor at oblique angles, while the color correction is essential to match the spectral sensitivity of the human eye, following the CIE Vλ (“V-lambda”) curve. These features ensure the measurements are precise and reliable.

The Role of Illumination in Various Applications

Illuminance, the luminous flux in a given area, is a crucial factor in many professional and everyday settings. The HI97500 can be used in a wide range of applications, such as assessing lighting levels in offices, schools, and hospitals to ensure they meet health and safety standards. It is also valuable in photography and cinematography to measure light intensity for optimal exposure. In agriculture and horticulture, it helps in monitoring light conditions for plant growth, while in civil engineering, it can be used to check the illumination of roads, tunnels, and public spaces.

Power and Battery Management

The HI97500 is powered by a single 9V alkaline battery. The battery compartment is located on the back of the meter, and the user must pay attention to its polarity when installing or replacing it. The automatic shut-off feature, which activates after 7 minutes of non-use, helps to conserve battery life. The low battery indicator, a blinking “V” on the LCD, signals that only a few hours of battery life remain. It is recommended to replace the battery immediately when this indicator appears to avoid unreliable measurements.

Warranty and Service

Hanna Instruments meters, including the HI97500, are warranted for two years against defects in workmanship and materials when used for their intended purpose. Sensors and probes have a six-month warranty. This warranty is limited to free repair or replacement and does not cover damages due to accidents, misuse, tampering, or lack of maintenance. If service is needed, you should contact the dealer where you purchased the instrument. If the instrument needs to be returned to Hanna Instruments, you must first obtain a Returned Goods Authorization Number.
