Marine Phosphate Ultra Low Range Checker® HC - HI774
Marine Phosphate Ultra Low Range Checker® HC - HI774
Details
The HI774 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphate in marine systems including coral reef tanks. Phosphate is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI774 provides quick, accurate results. For those that would like measure phosphate as phosphorous we off the HI736 Phosphorous Checker® HC. Alternatively, to determine the fraction of phosphorous (PO4-P) there is in phosphate (PO43-) the phosphate reading is multiplied by 0.3261. A 0.50 ppm phosphate reading is equal to 0.163 ppm or 163 ppb phosphorous.
Features at a Glance
Pre-mixed Chemistry
- Reagents are pre-measured packets that are added to the sample to take a reading.
Colorimetric Readings
- Using an LED at a specific wavelength and silicon photo detector the HI774 can perform a precise reading of the color change in the sample based on the phosphate concentration.
Checker HC Calibration Standards
- The HI774-11 CAL-Check standards can be purchased separately and are used to check the performance of the meter to ensure confidence that the meter is working properly.
Automatic Shut-off
- The meter is programmed to turn off after seven minutes of non-use or two minutes after taking a reading.
Long Battery Life
- The phosphate ULR Checker has an exceptional battery life with a fresh battery lasting for a minimum of 5000 measurements.
Plastic Carrying Case
- The 774 is supplied complete with meter and reagents for 10 tests that are packaged in a durable plastic carrying case.
Economical
- Laboratory grade measurements at a cost of a chemical test kit.
