功能
- High-Performance Device for Measuring Turbidity and Residual Chlorine Using Only This Single Device Uses a state-of-the-art optical system and a tungsten light source based on EPA standards. This single device can measure turbidity, free chlorine, and total chlorine with high accuracy. You will appreciate its accuracy, especially in measuring turbidity at low concentrations (below 0.05 NTU).
- 【 Main Features 】 High accuracy turbidity measurement even in low concentration range
- Validator for numerical verification and calibration (residual chlorine)
- Unique tag identification device for recording various measurements in the field
- Ability to calibrate turbidity at 2, 3, and 4 points
- Ability to connect a PC using USB or RS232
- Ability to check calibration status with GLP function
- Ability to memorize up to 200 measurement results
- Backlight for increased efficiency
- Auto power off when not in use
- Battery level indicator when power is on
- Current time is always displayed on the LCD
