The Hanna Instruments HI97105 Marine Master Multiparameter Photometer is the perfect solution for any aquarium user needing to accurately determine the pH, alkalinity, calcium, nitrate, nitrite, and phosphate levels in their marine biology applications. With lab-quality accuracy and a user-friendly design, this photometer combines precision and ease of use in a simple, portable design.

The advanced optical system doesn't require a warm-up time to take measurements and provides accurate results quickly. The tutorial mode provides easy, step-by-step instructions, making it ideal for even the most novice users. The CAL CheckTM feature ensures optimal performance and calibration verification, giving you confidence in your results.

The HI97105 Marine Master Photometer uses a colorimetric method for alkalinity, calcium, nitrate, nitrite, and phosphate measurements, which results in a distinctive range of colors from yellow to greenish blue. For pH measurements, the photometer uses a colorimetric adaptation of the Phenol Red Method, which is highly accurate and easy to use.

This photometer has a number of impressive specifications, including a range of 0.0 to 20.0 dkH (0 to 357 ppm as CaCO3) for alkalinity, marine. The calcium, marine range is 200 to 600 ppm. The nitrate range is 0.00 to 5.00 ppm (as NO3¯) and 0.0 to 75.0 ppm (as NO3¯), with accuracy up to 0 to 200 ppb (as NO2¯-N). The nitrite, marine ULR range is 0 to 200 ppb (as NO2¯-N), and the pH range is 6.3 to 8.6 pH. The phosphate, LR range is 0.00 to 0.90 ppm, and the light source is a light emitting diode.

The HI97105 Marine Master Photometer has 200 readings logging capacity, and its power supply is 1.5 V AA Alkaline (3 pcs.) with an auto-off feature after 15 minutes of inactivity (30 minutes before a READ measurement). The Environment range is 0 to 50 °C (32 to 122 °F); 0 to 100% RH, non-serviceable. It is 142.5 x 102.5 x 50.5 mm (5.6 x 4.0 x 2.0") with a weight of 380 g (13.4 oz.) with batteries.
