HI-97105 Marine Master Photometer
In Stock 9 Items available
HI-97105
The HI-97105 is designed to accurately determine all Marine pH, Ammonia, Alkalinity, Calcium, Magnesium, Nitrate LR & HR, Nitrite ULR, and Phosphate ULR levels in aquariums and marine biology applications.
The HI-97105 Marine Master Photometer combines accuracy and ease of use in a simple, portable design.
The advanced optical system provides lab-quality accuracy, while its user-friendly design is easy for any aquarium user, making it the perfect photometer for your water quality testing needs.
- No warm up time needed before taking a measurement.
- Tutorial mode for easy step-by-step instructions
- CAL CheckTM for performance verification and calibration
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.

Advanced Optical System
A Light Emitting Diode (LED) provides more light while using less power, and a narrow band interference filter results in more accurate and repeatable readings.
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.
Portable Design
Made to fit comfortably in your hand for on-the-go testing or sit on a table for benchtop use, a backlit LCD display provides at-a-glance readings from any angle - day or night. The supplied AA batteries provide life for more than 800 measurements.
We believe that buying a meter should be simple. Your HI-97105 photometer has many of the necessary accessories needed for successful measurements.
