When it comes to measuring light intensity, having a reliable and accurate tool is crucial. Two popular options on the market are the Dr.meter LX1330B and the Extech LT300, both of which are high-quality light meters designed to provide precise readings in various environments. In this comparison, we'll delve into the features, specifications, and performance of these two devices to help you determine which one best suits your needs.
Design and Build
The Dr.meter LX1330B has a compact and lightweight design, making it easy to carry around in a pocket or bag. It weighs approximately 6 ounces and measures 5.5 x 2.5 x 1 inches, allowing for convenient storage and transport. The device features a durable plastic housing with a clear LCD display, providing excellent visibility of the measurement results.
In contrast, the Extech LT300 has a slightly larger and more rugged design, weighing around 8 ounces and measuring 6 x 3 x 1.5 inches. Its housing is made of a robust ABS plastic, ensuring protection against accidental drops and rough handling. The device also features a backlit LCD display, which enhances readability in low-light conditions.
Measurement Range and Accuracy
Both light meters offer an impressive measurement range, but with some differences. The Dr.meter LX1330B can measure light intensity from 0 to 200,000 lux (approximately 0 to 18,600 foot-candles), with an accuracy of ±3% ±1 digit. This makes it suitable for a wide range of applications, including industrial, commercial, and residential lighting assessments.
The Extech LT300, on the other hand, has a slightly narrower measurement range of 0 to 50,000 lux (approximately 0 to 4,650 foot-candles), but with an improved accuracy of ±2% ±1 digit. This device is particularly well-suited for applications where high precision is required, such as in photography, cinematography, or medical lighting assessments.
Features and Functions
Both light meters come with a range of features that enhance their functionality and usability. The Dr.meter LX1330B includes:
- Automatic shut-off to conserve battery life
- Data hold function for easy reading and recording of measurements
- Zero adjustment for calibration purposes
The Extech LT300 offers:
- Manual and automatic ranging for flexibility in measurement settings
- Min/Max/Avg recording modes for tracking changes in light intensity over time
- A built-in infrared thermometer for measuring surface temperatures (optional)
Power and Battery Life
The Dr.meter LX1330B is powered by a single 9V battery, which provides approximately 30 hours of continuous operation. The Extech LT300, on the other hand, uses three AAA batteries, offering around 20 hours of continuous use.
Conclusion
In conclusion, both the Dr.meter LX1330B and the Extech LT300 are high-quality light meters that offer excellent performance and accuracy in measuring light intensity. While they share some similarities, each device has its unique features and strengths, making them suitable for different applications and user needs.
If you're looking for a compact and affordable light meter with a wide measurement range, the Dr.meter LX1330B might be the better choice. However, if you require higher precision and a more rugged design, the Extech LT300 is likely to be the preferred option.
Ultimately, when selecting between these two light meters, consider your specific requirements and the environments in which you'll be using the device. By doing so, you'll be able to choose the best tool for your needs and ensure accurate and reliable measurements.
