With an IP67-rated waterproof casing, the photometer is built to endure harsh environmental conditions, making it ideal for both field and laboratory applications. The intuitive backlit dot matrix LCD provides clear on-screen instructions, enabling easy operation even in low-light environments. The dedicated CAL Check™ function ensures reliable performance by offering a simple calibration verification process, essential for maintaining precision over time. Additionally, the device supports automatic data logging, storing up to 50 measurements for easy recall and analysis. This photometer is particularly suited for water treatment facilities, environmental monitoring projects, and industrial applications requiring rigorous water quality control.

Better Features for Better Testing

Let your photometer guide you through setup, calibration, and testing with on-screen tutorials and animations so you always know the next step. Simply access Tutorial Mode at any stage in the setup or measurement process with the dedicated help key. The auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on. When the battery level is below 10%, a warning symbol will blink to indicate low battery condition. When low battery power may affect your results, the meter will shut down to avoid erroneous readings caused by low battery level.

Data Logging

Missed a measurement? No need to worry because your photometer will automatically log the last 50 measurements. The results can be viewed instantly using the Log Recall Menu.

CAL CheckTM Validation

Hanna’s exclusive CAL CheckTM feature provides a stress-free, straightforward way to ensure your photometer is working properly. Simply insert the certified CAL CheckTM standards and let your meter guide you through validation. If your photometer is out of specification for any reason, simply calibrate to your standard.

Built Better

Designed to withstand the knocks, drops, and spills of real life, the new IP67 body ensures top performance in any environment. Internal optics are sealed from outside dust, dirt, and water. In addition, it floats, just in case you drop your meter in water. This photometer uses an exclusive positive‑locking system to ensure that the cuvettes are placed into the holder in the same position for accurate readings every time.
